Defining Correlation 

Use

Correlation must be defined for bi-directional data objects of type standard of which new instances can be created in the client application for insertion in the back-end database.

Prerequisites

You have created a data object and added the nodes.

Procedure

...

       1.      Log on to the NetWeaver AS and start transaction SDOE_WB.

       2.      In the Data Orchestration Workbench, navigate to the required node, click with the secondary mouse button and choose Change.

       3.      Click the Explicit Key Mapping pushbutton.

       4.      Click the Correlation Fields tab.

       5.      Select the correlation type.

More information: Correlation

       6.      Set the indicator in the Correlation Field column for the field that is to be used as a correlation field.

If one field is not sufficient to provide enough correlation information, you can set the indicator for as many fields as are necessary. This allows the Data Orchestration Engine (DOE) to correlate the instances that are sent from the DOE to the back-end system and those sent back by the back-end system.

The BAPI wrapper used in the back-end adapter for the data object must include the fields you define as the correlation fields, so you must only select fields defined as back-end fields. If you want to use the node’s synchronization key (SyncKey) for correlation, you must define it as a back-end field and adjust the BAPI wrapper accordingly, as it does not include the SyncKey.

       7.      Choose Save.
