• What is the cause and solution for SAP error message SADL_GW_CUD_CONTR023 - No key fields given for active node ?

  The SAP error message SADL_GW_CUD_CONTR023: No key fields given for active node typically occurs in the context of the SAP Gateway and the SAP Data Access Layer (SADL) when trying to perform a Create, Update, or Delete (CUD) operation on an entity that requires key fields to identify the record but none have been provided.
  Cause:
  
  Missing Key Fields: The most common cause of this error is that the request to the SAP Gateway does not include the necessary key fields that uniquely identify the entity you are trying to manipulate. In SAP, key fields are essential for identifying records in the database.
  Incorrect Mapping: There may be an issue with the mapping of the entity in the SADL configuration, where the key fields are not correctly defined or recognized.
  Data Model Issues: The underlying data model may not be correctly set up, leading to the absence of key fields in the request.
  
  Solution:
  
  Check Request Payload: Ensure that the request payload being sent to the SAP Gateway includes all required key fields for the entity you are trying to create, update, or delete. This typically involves checking the JSON or XML structure of the request.
  Review Entity Definition: Go to the SADL configuration and verify that the entity definition includes the correct key fields. You can do this in the SAP Gateway Service Builder (transaction code SEGW).
  Update Service Implementation: If you are implementing a custom service, ensure that the implementation correctly handles the key fields. This may involve modifying the code to ensure that key fields are being passed and processed correctly.
  Test with Sample Data: Use sample data that includes all necessary key fields to test the service and ensure that it works as expected.
  Check for Updates: Ensure that your SAP system is up to date with the latest support packages and notes, as there may be fixes related to this error in newer versions.
