  The SAP error message CNV_20800148 typically occurs during the execution of a data migration or conversion process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that changes made in the current session were not saved, and instead, the settings from a previous run will be applied.
  Cause:
  
  Session Timeout: The session may have timed out, causing the system to discard unsaved changes.
  Incomplete Data Entry: Required fields may not have been filled out correctly, leading to the inability to save changes.
  Technical Issues: There may be underlying technical issues, such as database locks or connectivity problems, that prevent saving.

  Reapply Changes: If the changes were not saved, you may need to reapply them manually and ensure that you save them before proceeding.
