SAP Gateway Connection
This documentation is based on version 21.0.8257 of the connector.
This documentation is based on version 21.0.8257 of the connector.
The connector leverages the SAP Gateway API to enable bidirectional access to SAP services that use the gateway. This includes but is not limited to S/4 HANA, S/4 HANA Cloud, ERP, and any other editions that support the SAP Gateway.
Set the following connection properties to access SAP Gateway tables.
SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts.
In basic authentication, you use your login credentials to connect. Set the following properties:
You can connect without setting any connection properties for your user credentials. Set InitiateOAuth to GETANDREFRESH to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
When you connect, the connector opens the SAP Gateway OAuth endpoint in your default browser. Log in and grant permissions to the connector. The connector then completes the following OAuth process:
See Using OAuth Authentication for other OAuth authentication flows.
To connect using an ApiKey, set the APIKey property, and you are ready to connect.
In order to acquire an APIKey, open the Developer Portal and select the Product or Service for which you have published the API. Then, click on Subscribe > Create a new Application. After filling the necessary information and creating the application, the Application Key is going to be displayed. You can copy this value into the APIKey connection property.
You may set the AuthScheme to Token to enforce the Token based Authentication scheme.OAuth requires the authenticating user to interact with SAP Gateway using the browser. The connector facilitates this in various ways as described below.
You can register an app to obtain the OAuthClientId and OAuthClientSecret.
NOTE : The password you choose when creating a service user as explained in Creating a Custom OAuth App, must be provided via OAuthClientSecret property.
You need to create a custom OAuth app in order to connect to SAP Gateway.
See Creating a Custom OAuth App for information on how to create a custom app.
Creating a custom OAuth app is required all cases when connecting via OAuth.
After setting the following, you are ready to connect:
To create SAP Gateway data sources on headless servers or other machines on which the connector cannot open a browser, you need to authenticate from another machine. Authentication is a two-step process.
Create a Custom OAuth App
Creating a custom OAuth app is required in the headless OAuth flow.
See Creating a Custom OAuth App for a procedure. You can then follow the procedures below to authenticate and connect to data.
Obtain a Verifier Code
Set the following properties on the headless machine:
You can then follow the steps below to authenticate from another machine and obtain the OAuthVerifier connection property.
On the headless machine, set the following connection properties to obtain the OAuth authentication values:
After the OAuth settings file is generated, set the following properties to connect to data:
Transfer OAuth Settings
Follow the steps below to install the connector on another machine, authenticate, and then transfer the resulting OAuth values.
On a second machine, install the connector and connect with the following properties set:
Test the connection to authenticate. The resulting authentication values are written, encrypted, to the path specified by OAuthSettingsLocation. Once you have successfully tested the connection, copy the OAuth settings file to your headless machine. On the headless machine, set the following connection properties to connect to data:
Creating a custom OAuth app is required in all cases.
To create a custom OAuth app, follow the steps in this article, OAuth 2.0 Client Registration
Note: Redirect URL needs to be set to https://oauth.cdata.com/oauth/ in APP AuthMode flow.
This section details a selection of advanced features of the SAP Gateway connector.
The connector allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.
Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.
To configure the connector using Private Agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.
The Jitterbit Connector for SAP Gateway allows you to define a virtual table whose contents are decided by a pre-configured query. These are called User Defined Views, which are useful in situations where you cannot directly control the query being issued to the driver, e.g. when using the driver from Jitterbit. The User Defined Views can be used to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.
There are two ways to create user defined views:User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.
You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.
This User Defined View configuration file is formatted as follows:For example:
{ "MyView": { "query": "SELECT * FROM SampleTable_1 WHERE MyColumn = 'value'" }, "MyView2": { "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)" } }Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:
"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"
SELECT * FROM Customers WHERE City = 'Raleigh';An example of a query to the driver:
SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';Resulting in the effective query to the source:
SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';That is a very simple example of a query to a User Defined View that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.
By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.
To specify another certificate, see the SSLServerCert property for the available formats to do so.
The Jitterbit Connector for SAP Gateway models SAP Gateway entities in relational Tables, Views, and Stored Procedures. The table definitions are dynamically obtained from the OData service you connect to. Any changes in the metadata, such as added or removed columns or changes in data type, can be loaded by reconnecting.
The connector models the writable entity sets and singletons described in the service metadata document as bidirectional Tables.
Some OData entities can only be accessed through Navigation Properties. By default, the connector models navigation properties as separate views. See Views for more information on querying navigation properties.
NOTE: Stored procedures are not currently supported. See the above note for details.
Stored Procedures are function-like interfaces to the data source. They can be used to search, update, and modify information in the data source.
The connector exposes tables for every entity set and singleton defined on the OData service document. Entities on these tables may be inserted, updated, or deleted using standard SQL insert, update, or delete statements.
The connector supports OData deep inserts, in which you simultaneously create a base entity and link it to related entities, by specifying navigation properties. To specify Navigation Properties for an entity, you create a temporary table for the navigation property and then reference the temporary table in the insert to the base table. Reference the temporary table in the appropriate navigation property column on the base table. Each navigation property column is prefixed with the word "Linked".
Note that you must define the temporary tables and insert to the base entity within the same connection.
For example, consider the GWSAMPLE_BASIC service. On GWSAMPLE_BASIC, there is a SalesOrder table. When creating a SalesOrder, you must specify a new SalesOrderLineItem and an existing BusinessPartner. To do so, you can specify the following navigation properties.
Insert the related entities into temporary tables that correspond to each navigation property. You can specify an existing entity's primary key or you can insert a new entity.
INSERT INTO SalesOrderLineItems#TEMP (ProductID, Quantity) VALUES ('P001', 15)
INSERT INTO SalesOrderLineItems#TEMP (ProductID, Quantity) VALUES ('P002', 10)
INSERT INTO BusinessPartners#TEMP (BusinessPartnerID)
VALUES ('BP001')
Note: BusinessPartner can also be specified via the CustomerID property directly on the SalesOrder. This example is not using that column due to the possibility that a suitable foreign key may not always be available.
The Jitterbit Connector for SAP Gateway will assume that the BusinessPartner already exists and will only link to the existing references since only the primary keys was specified. When more than just the primary key is defined, such as the example for SalesOrderLines, the Jitterbit Connector for SAP Gateway will attempt to create new entries - triggering the deep insert.In the INSERT statement for the base entity, reference the temporary tables in the LinkedToLineItems and LinkedToBusinessPartner columns:
INSERT INTO SalesOrders (Note, LinkedToLineItems, LinkedToBusinessPartner)
VALUES ('New sales order', 'SalesOrderLineItems#TEMP', 'BusinessPartners#TEMP')
Connection conn = DriverManager.getConnection(connectionStr);
Statement stat = conn.createStatement();
stat.executeUpdate("INSERT INTO SalesOrderLineItems#TEMP (ProductID, Quantity) VALUES ('P001', 15)");
stat.executeUpdate("INSERT INTO SalesOrderLineItems#TEMP (ProductID, Quantity) VALUES ('P002', 10)");
stat.executeUpdate("INSERT INTO BusinessPartners#TEMP (BusinessPartnerID) VALUES ('BP001')");
stat.executeUpdate("INSERT INTO SalesOrders (Note, LinkedToLineItems, LinkedToBusinessPartner) VALUES ('New sales order', 'SalesOrderLineItems#TEMP', 'BusinessPartners#TEMP')");
stat.close();
By default, the connector models Navigation Properties as separate views. The views are named in the format ParentTable_NavigationProperty.
For an example of working with a navigation property as a view, consider the GWSAMPLE_BASIC service. The SalesOrder entity has the ToLineItems navigation property. The Jitterbit Connector for SAP Gateway will display a view called SalesOrders_ToLineItems. Retrieving data from SalesOrders_ToLineItems will display the SalesOrderLineItems objects associated with a given SalesOrder. The SalesOrders_ToLineItems view has a primary key made up of the ID of the parent entity and the ID of the related entity.
Note that the GWSAMPLE_BASIC sample service also contains foreign keys directly on each entity, such as a SalesOrderID directly on the SalesOrderLineItems table. In this case, the same effect can be achieved by simply retrieving data from the SalesOrderLineItems table directly. However, it is not a requirement in OData to have these foreign keys, nor is it a guarantee that each navigation property will be exposed individually as thier own table. Since there is no way of knowing beforehand what might be exposed on its own endpoint, the Jitterbit Connector for SAP Gateway will display both the view and the table. In general, it is best to use Tables when available, and views only when necessary (ie: not table is displayed, or no foreign keys can be used to identify relationships).NOTE: Stored procedures are not currently supported. See the above note for details.
Stored procedures* are available to complement the data available from the Data Model. It may be necessary to update data available from a view using a stored procedure* because the data does not provide for direct, table-like, two-way updates. In these situations, the retrieval of the data is done using the appropriate view or table, while the update is done by calling a stored procedure. Stored procedures* take a list of parameters and return back a dataset that contains the collection of tuples that constitute the response.

Describes the SELECT query processing that the connector can offload to the data source.
When working with data sources that do not support SQL-92, you can query the sys_sqlinfo view to determine the query capabilities of the underlying APIs, expressed in SQL syntax. The connector offloads as much of the SELECT statement processing as possible to the server and then processes the rest of the query in memory.
Below is an example data set of SQL capabilities. The following result set indicates the SELECT functionality that the connector can offload to the data source or process client side. Your data source may support additional SQL syntax. Some aspects of SELECT functionality are returned in a comma-separated list if supported; otherwise, the column contains NO.

The following options are available:
The client ID assigned when you register your application with an OAuth authorization server.
string
""
As part of registering an OAuth application, you will receive the OAuthClientId value, sometimes also called a consumer key, and a client secret, the OAuthClientSecret.
The client secret assigned when you register your application with an OAuth authorization server.
string
""
As part of registering an OAuth application, you will receive the OAuthClientId, also called a consumer key. You will also receive a client secret, also called a consumer secret. Set the client secret in the OAuthClientSecret property.
The access token for connecting using OAuth.
string
""
The OAuthAccessToken property is used to connect using OAuth. The OAuthAccessToken is retrieved from the OAuth server as part of the authentication process. It has a server-dependent timeout and can be reused between requests.
The access token is used in place of your user name and password. The access token protects your credentials by keeping them on the server.
The OAuth callback URL to return to when authenticating. This value must match the callback URL you specify in your app settings.
string
""
During the authentication process, the OAuth authorization server redirects the user to this URL. This value must match the callback URL you specify in your app settings.
The permission scopes in space separated values. This is required when authenticating via OAuth2.0 flow.
string
""
The permission scopes you have configured when creating the service user for the OAuth 2.0 client, in space separated values. This is required when authenticating via OAuth2.0 flow.
The verifier code returned from the OAuth authorization URL.
string
""
The verifier code returned from the OAuth authorization URL. This can be used on systems where a browser cannot be launched such as headless systems.
See to obtain the OAuthVerifier value.
Set OAuthSettingsLocation along with OAuthVerifier. When you connect, the connector exchanges the OAuthVerifier for the OAuth authentication tokens and saves them, encrypted, to the specified file. Set InitiateOAuth to GETANDREFRESH automate the exchange.
Once the OAuth settings file has been generated, you can remove OAuthVerifier from the connection properties and connect with OAuthSettingsLocation set. To automatically refresh the OAuth token values, set OAuthSettingsLocation and additionally set InitiateOAuth to REFRESH.The OAuth refresh token for the corresponding OAuth access token.
string
""
The OAuthRefreshToken property is used to refresh the OAuthAccessToken when using OAuth authentication.
The lifetime in seconds of the OAuth AccessToken.

string
""
Pair with OAuthExpiresIn to determine when the AccessToken will expire.
This section provides a complete list of SSL properties you can configure.
Property | Description |
SSLServerCert | The certificate to be accepted from the server when connecting using TLS/SSL. |
The certificate to be accepted from the server when connecting using TLS/SSL.
string
""
If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.
This property can take the following forms:
Description | Example |
A full PEM Certificate (example shortened for brevity) | -----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE----- |
A path to a local file containing the certificate | C:\cert.cer |
The public key (example shortened for brevity) | -----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY----- |
The MD5 Thumbprint (hex values can also be either space or colon separated) | ecadbdda5a1529c58a1e9e09828d70e4 |
The SHA1 Thumbprint (hex values can also be either space or colon separated) | 34a929226ae0819f2ec14b4a3d904f801cbb150d |
If not specified, any certificate trusted by the machine is accepted.
Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).
Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.
This section provides a complete list of schema properties you can configure.
Property | Description |
Location | A path to the directory that contains the schema files defining tables, views, and stored procedures. |
BrowsableSchemas | This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC. |
Tables | This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA, TableB, TableC. |
Views | Restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC. |
UseDisplayNames | Boolean determining whether or not to use SAP labels. |
A path to the directory that contains the schema files defining tables, views, and stored procedures.
string
"%APPDATA%\\SAPGateway Data Provider\Schema"
The path to a directory which contains the schema files for the connector (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is "%APPDATA%\\SAPGateway Data Provider\Schema" with %APPDATA% being set to the user's configuration directory:
Platform | %APPDATA% |
Windows | The value of the APPDATA environment variable |
Mac | ~/Library/Application Support |
Linux | ~/.config |
This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
string
""
Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.
This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
string
""
Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the connector.
This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.
Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.
Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

If set to true, the labels you have configured in your account for the OData properties, will serve as column names. Otherwise, the name of the property will be the column name.
This section provides a complete list of miscellaneous properties you can configure.
Property | Description |
DataFormat | The data format to retrieve data in. Select either XML or JSON. |
MaxRows | Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time. |
Other | These hidden properties are used only in specific use cases. |
Pagesize | The maximum number of results to return per page from SAP Gateway. |
PseudoColumns | This property indicates whether or not to include pseudo columns as columns to the table. |
Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
The data format to retrieve data in. Select either XML or JSON.
string
"XML"
The data format to retrieve data in. Possible values are JSON and XML. If not specified, XML will be set by default.
Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
int
-1
Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
These hidden properties are used only in specific use cases.
string
""
The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.
Specify multiple properties in a semicolon-separated list.
DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
ConvertDateTimeToGMT | Determines whether to convert date-time values to GMT, instead of the local time of the machine. |
RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
The maximum number of results to return per page from SAP Gateway.
int
5000
The Pagesize property affects the maximum number of results to return per page from SAP Gateway. Setting a higher value may result in better performance at the cost of additional memory allocated per page consumed.
This property indicates whether or not to include pseudo columns as columns to the table.
string
""
This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".
The value in seconds until the timeout error is thrown, canceling the operation.
int
60
If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.
If Timeout expires and the operation is not yet complete, the connector throws an exception.
