  The SAP error message MFLE_CHANGEDOC018 indicates that there is an issue with obsolete field metadata in the context of Change Document functionality. This error typically arises when there is a mismatch or absence of conversion definitions for fields that are no longer valid or have been changed in the system.
  Cause:
  
  Obsolete Field Metadata: The error suggests that the system is trying to access or convert data for a field that has been marked as obsolete. This can happen if the field has been removed or modified in the data model but still exists in the change document configuration.
  Missing Conversion Definitions: The system expects a conversion routine for the field, but it is not defined, leading to this error.
  Data Model Changes: Changes in the underlying data model (like changes in database tables or structures) can lead to inconsistencies in the change document settings.
  
  Solution:
  
  Check Change Document Configuration: Review the change document configuration for the relevant object. Ensure that all fields are correctly defined and that obsolete fields are removed from the configuration.
  Update Metadata: If fields have been changed or removed, update the metadata accordingly. This may involve regenerating the change document settings or adjusting the data model.
  Define Conversion Routines: If the field is still relevant but lacks a conversion routine, define the necessary conversion logic in the system.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on handling obsolete fields in change documents.
  Testing: After making changes, test the functionality to ensure that the error no longer occurs and that the change documents are being generated correctly.
