  The SAP error message UC064 indicates that there is a mismatch between the segment name and the conversion rule in the context of IDoc processing. This typically occurs when the IDoc structure does not align with the expected format defined in the conversion rules.
  Cause:
  
  Mismatch in Segment Definition: The segment name specified in the IDoc does not correspond to the segment defined in the conversion rules.
  Incorrect Mapping: The mapping between the IDoc segments and the target structure may be incorrectly defined.
  Changes in IDoc Structure: If there have been recent changes to the IDoc structure or the conversion rules, this could lead to inconsistencies.
  Configuration Issues: Incorrect configuration in the IDoc processing settings or the associated message types.

  Test IDoc Processing: After making the necessary adjustments, test the IDoc processing again to see if the error persists. You can use transaction WE19 to simulate IDoc processing.
