• What is the cause and solution for SAP error message 53128 - Do not change key fields when deleting ?

  The SAP error message 53128, "Do not change key fields when deleting," typically occurs when you attempt to delete a record in the SAP system, but the system detects that key fields (fields that uniquely identify a record) are being modified or changed during the deletion process. This is not allowed because key fields must remain constant to ensure data integrity.
  Cause:
  
  Modification of Key Fields: The most common cause of this error is that the program or transaction you are using is trying to change key fields of a record that is being deleted.
  Incorrect Logic in Custom Code: If you are using custom ABAP code or enhancements, there may be logic that inadvertently modifies key fields during the deletion process.
  Data Integrity Rules: SAP enforces strict data integrity rules, and changing key fields while deleting a record violates these rules.
  
  Solution:
  
  Review the Deletion Process: Ensure that you are not trying to change any key fields in the record you are attempting to delete. Key fields should remain unchanged.
  Check Custom Code: If you are using custom ABAP programs or enhancements, review the code to ensure that it does not modify key fields during the deletion process. Look for any UPDATE or MODIFY statements that might be affecting key fields.
  Use Correct Transaction: Make sure you are using the correct transaction for deletion. Some transactions may have specific requirements regarding key fields.
  Consult Documentation: Refer to SAP documentation or help files related to the specific transaction or module you are working with to understand the requirements for deletion.
  Test in Development: If you are making changes to custom code, test your changes in a development environment before moving to production.
  
  Related Information:
  
  Key Fields: Key fields are typically defined in the data dictionary (DDIC) of the SAP system and are crucial for identifying records uniquely.
  Data Integrity: SAP systems are designed to maintain data integrity, and any operation that could compromise this integrity is restricted.
  Error Handling: If you encounter this error frequently, consider implementing error handling in your custom code to catch and log such issues for further analysis.
  
  If the issue persists after checking these points, it may be beneficial to consult with your SAP Basis or ABAP team for further investigation.
