• What is the cause and solution for SAP error message ESH_ENG_CDS_ABAP077 - Severe inconsistency: DDIC-view &1 defined also by CDS-entity &2 ?

  The SAP error message ESH_ENG_CDS_ABAP077 indicates a severe inconsistency where a Data Dictionary (DDIC) view is defined in a way that conflicts with a Core Data Services (CDS) entity. This typically occurs when both the DDIC view and the CDS entity are trying to define the same data structure or have overlapping definitions, leading to ambiguity in the system.
  Cause:
  
  Duplicate Definitions: The error arises when a DDIC view and a CDS entity are defined with the same name or are trying to access the same underlying database table or structure.
  Inconsistent Metadata: There may be inconsistencies in the metadata definitions between the DDIC and CDS layers, leading to conflicts.
  Transport Issues: If changes were transported from one system to another, it might lead to inconsistencies if the transport was not handled correctly.
  
  Solution:
  
  Identify Conflicting Objects: Use transaction codes like SE11 (Data Dictionary) and SE80 (Object Navigator) to locate the DDIC view and the CDS entity that are causing the conflict. Check their definitions and see how they overlap.
  Rename or Remove: If possible, rename one of the conflicting objects (either the DDIC view or the CDS entity) to eliminate the conflict. If the DDIC view is not needed, consider removing it.
  Adjust Definitions: Ensure that the definitions of the DDIC view and the CDS entity do not overlap. This may involve modifying the fields, structure, or the underlying database tables.
  Check Transport Requests: If the issue arose after a transport, check the transport requests to ensure that all necessary objects were included and that there are no missing dependencies.
  Re-activate Objects: After making changes, re-activate both the DDIC view and the CDS entity to ensure that the system recognizes the updates.
