  The SAP error message SADL_GW_PUSHDOWN_GEN001 typically indicates that there is an issue related to the deletion of an entity in the context of the SAP Gateway and the Service Data Layer (SDAL). The error message states: "Deletion error: &1 not found in annotation &2", where &1 represents the entity that could not be found, and &2 represents the annotation that is being referenced.
  Cause:
  
  
  Entity Not Found: The primary cause of this error is that the entity you are trying to delete does not exist in the database or the context of the operation. This could happen if:
  
  The entity was already deleted.
  The entity ID provided is incorrect.
  There is a mismatch between the entity and the annotations defined in the service.
  
  
  
  Annotation Issues: The error may also arise from issues with the annotations in the OData service. If the annotations do not correctly reflect the underlying data model or if there are inconsistencies, it can lead to this error.
  
  
  Authorization Issues: Sometimes, the user may not have the necessary permissions to delete the entity, which can also trigger similar error messages.
  
  
  Solution:
  
  
  Verify Entity Existence: Check if the entity you are trying to delete actually exists in the database. You can do this by querying the database or using the relevant transaction codes in SAP to confirm the entity's existence.
  
  
  Check Entity ID: Ensure that the ID of the entity you are trying to delete is correct. Double-check the input parameters being passed to the deletion function.
  
  
  Review Annotations: Look into the annotations defined in your OData service. Ensure that they are correctly set up and that they match the underlying data model. You may need to regenerate the service or update the annotations if there are discrepancies.
  
  
  Authorization Check: Ensure that the user performing the deletion has the necessary authorizations to delete the entity. You can check the user's roles and authorizations in the SAP system.
  
  
  Debugging: If the issue persists, consider debugging the OData service to trace the exact point of failure. This can provide more insights into what might be going wrong.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for any known issues or patches related to this error message.
