  The change document object (e.g., MATERIAL, VENDOR, CUSTOMER) is not properly defined or activated in the system.
  The object might not be assigned to the relevant table or structure.
  
  
  
  Change Document Object Not Created in the System:
  
  The change document object might not exist in the system or is not generated via transaction SCDO.

  Custom Development Issues:
  
  If the error occurs in a custom program or enhancement, the change document object might not be properly handled or created.
  
  
  
  
  Solution
  
  
  Check and Activate Change Document Object:
  
  Use transaction SCDO (Change Document Objects) to check if the change document object exists.
  If it does not exist, create it or activate it.
  Ensure that the change document object is properly linked to the relevant tables or structures.
  
  
  
  Generate Change Document Object:
  
  In transaction SCDO, after creating or modifying the object, generate the object to create the necessary function modules and structures.
  
  
  
  Check Authorization:
  
  Verify that the user or background job has the necessary authorizations to create change documents.
  
  
  
  Review Custom Code:
  
  If the error occurs in custom code, check the implementation of change document creation.
  Ensure that the function modules related to change documents (e.g., CHANGE_DOCUMENT_OPEN, CHANGE_DOCUMENT_UPDATE, CHANGE_DOCUMENT_CLOSE) are correctly called.
  
  
  
  Check System Logs and Tables:
  
  Look for inconsistencies or errors in tables CDHDR and CDPOS.
  Check system logs (SM21) and short dumps (ST22) for related errors.
  
  
  
  SAP Notes and Support:
  
  Search for relevant SAP Notes that might address known issues with change document objects.
