  SAP Error Message:
  WER428 - Modification not allowed, element &1 is not in edit mode
  
  
  Cause:
  This error occurs when you try to modify an object or element in the SAP system that is currently not in edit mode. In SAP, certain objects (like customizing entries, development objects, or configuration elements) must be explicitly put into edit mode before changes can be made. If you attempt to change an element that is locked or only available in display mode, the system prevents the modification and raises this error.
  Common scenarios include:
  
  Trying to change a customizing object without unlocking it first.
  Attempting to edit a transport request or a development object that is locked or released.
  Modifying a configuration element in IMG without switching to edit mode.
  Working in a client or system where changes are not allowed (e.g., production system or locked client).
