  The SAP error message WC162, which states "Change message simulation: no database changes," typically occurs during the simulation of a change message in the SAP system. This message indicates that the system did not detect any changes in the database that would trigger the generation of a change message.
  Causes:
  
  No Changes Made: The most straightforward cause is that there were no actual changes made to the data that would warrant a change message.
  Incorrect Configuration: The configuration settings for change message processing may not be set up correctly, leading to the system not recognizing changes.

  Solutions:
  
  Verify Changes: Ensure that the changes you expect to trigger a message have indeed been made. Check the relevant data in the database.
  Check Configuration: Review the configuration settings for change message processing in the relevant transaction (e.g., transaction codes related to message control).
  Run in Actual Mode: If you are in simulation mode, try running the process in actual mode to see if it generates the expected change messages.
  Review Authorizations: Ensure that you have the necessary authorizations to make changes and trigger messages.
  Check for Locks: Investigate if there are any locks on the data that might prevent changes from being recognized.
