• What is the cause and solution for SAP error message COM_DIFF_KEY028 - No changes were made ?

  The SAP error message COM_DIFF_KEY028: No changes were made typically occurs in the context of the SAP system when attempting to save or update a document or record, but the system detects that no actual changes have been made to the data. This can happen in various modules, including materials management (MM), sales and distribution (SD), or production planning (PP).
  Causes:
  
  No Data Changes: The most common cause is that the user is trying to save a record without making any changes to the fields. The system recognizes that the data is the same as it was before.
  Unintentional Save: The user may have inadvertently clicked the save button without modifying any data.
  Data Validation: Sometimes, the system may have validation rules that prevent changes from being saved if certain conditions are not met, leading to the perception that no changes were made.
  User Authorization: In some cases, the user may not have the necessary authorizations to make changes, leading to the system not allowing any updates.
  
  Solutions:
  
  Check for Changes: Ensure that you have actually made changes to the fields before attempting to save. Review the data you are trying to update.
  Review Input Fields: Double-check all input fields to confirm that they contain the intended values and that you are not trying to save the same data.
  Use the Correct Transaction: Make sure you are using the correct transaction code for the operation you are trying to perform.
