This typically occurs during the processing of IDocs, especially when dealing with EDI (Electronic Data Interchange) or other data transfer processes.
  Cause:
  The error message R8163 can be caused by several factors:

  Custom Development: If there are custom segments or fields added to the IDoc, they may not be properly defined in the DDIC.
  Versioning Issues: If there are different versions of the IDoc structure being used, it may lead to discrepancies in field definitions.
