  Check IDoc Type: Verify that the IDoc type being sent matches the expected IDoc type in the receiving system. Ensure that the correct IDoc type is being used.

  Version Compatibility: Check for version compatibility between the sender and receiver systems. If there are discrepancies, consider updating the systems or adjusting the IDoc structure to match.
