  The SAP error message ED188, which states "You can only use modification functions in their original area," typically occurs when there is an attempt to use modification functions (like user exits, BAdIs, or enhancement points) outside of their designated context or area. This can happen in various scenarios, such as when trying to modify standard SAP behavior in a way that is not allowed by the system.
  Cause:
