  Solution:
  
  
  Define Key Property:
  
  Ensure that the entity type in your OData service has a key property defined. You can do this in the Data Model (e.g., using SEGW transaction).
  Go to the Entity Type in the Data Model and check if the key property is marked correctly.

  Check for Duplicates:
  
  Ensure that there are no duplicate key properties defined in the entity type.
  
  
  
  Debugging:
