Summary :
In this SAP Note, the user encounters issue TR840 stating "System not set to changable" when attempting to modify postal codes via SE71. The system's restriction arises due to its configuration which disallows changes. To resolve, the user must log in as DDIC to adjust the "Set system changability" to "Change normally” through STMU. This action requires maximizing the window to ensure functionality. Users, following adjustment, can implement the desired updates. Post-modification, it is critical to revert the system’s changeability settings and reset the repair flag to maintain system integrity.
