• What is the cause and solution for SAP error message CFD_GW_UI013 - Only one data source extension can be modified within the same change set ?

  The SAP error message CFD_GW_UI013, which states "Only one data source extension can be modified within the same change set," typically occurs in the context of SAP Gateway and OData services when you are trying to modify multiple data source extensions in a single change set. This is a restriction in the way that change sets are handled in SAP Gateway.
  Cause:
  The error arises because the SAP Gateway framework enforces a rule that only one data source extension can be modified in a single change set. This is to ensure data integrity and consistency during the processing of requests. When you attempt to include multiple modifications to different data source extensions in the same change set, the system raises this error.
  Solution:
  To resolve this error, you need to separate your modifications into different change sets. Here are the steps you can take:
  
  
  Identify Modifications: Review the modifications you are trying to make and identify which data source extensions are involved.
  
  
  Separate Change Sets: Create separate change sets for each data source extension modification. This means that each change set should only contain one modification to a single data source extension.
  
  
  Execute Requests: Send the requests for each change set separately. This will allow the system to process each modification without encountering the restriction.
  
  
  Testing: After making the changes, test the functionality to ensure that the modifications have been applied correctly and that there are no further issues.
