• What is the cause and solution for SAP error message SD_CDS_PROJECTION007 - &1 primary Base Objects found for Projection View &2 ?

  The SAP error message SD_CDS_PROJECTION007 typically indicates that there is an issue with the projection view in the Core Data Services (CDS) layer, specifically that multiple primary base objects have been found for a given projection view. This can occur in scenarios where the projection view is expected to map to a single primary base object, but the system has identified more than one.
  Cause:
  
  Multiple Base Objects: The projection view is defined in such a way that it references multiple base objects that are marked as primary. This can happen due to incorrect definitions in the CDS view or misconfigurations in the underlying data model.
  Inconsistent Data Model: Changes in the underlying data model or the addition of new base objects without proper adjustments to the projection view can lead to this error.
  Incorrect Annotations: The annotations in the CDS view might not be correctly set, leading to ambiguity in determining the primary base object.
  
  Solution:
  
  Review the CDS View Definition: Check the definition of the projection view and ensure that it is correctly referencing only one primary base object. You may need to adjust the SQL view or the annotations.
  Check Base Objects: Identify the base objects that are being referenced in the projection view. Ensure that only one of them is marked as primary. If necessary, modify the base objects to ensure that only one is designated as primary.
  Adjust Annotations: If the projection view uses annotations to define its behavior, ensure that these annotations are correctly set to avoid ambiguity.
  Consult Documentation: Refer to SAP documentation or the SAP Community for specific guidelines on defining projection views and handling base objects.
  Testing: After making changes, test the projection view to ensure that the error is resolved and that the view behaves as expected.
