E0484 - Details

• The SAP error message E0484, "Activate the structures first," typically occurs when you are trying to perform an action that requires certain data structures to be activated in the system. This error is often encountered in the context of customizing or configuring SAP modules, particularly in areas like ABAP Dictionary, Data Elements, Domains, or when working with Business Configuration (BC) settings.
  
  Cause:
  The error is usually caused by one of the following reasons:
  
  Inactive Data Structures: The data structures (like tables, views, or data elements) that you are trying to use have not been activated. In SAP, changes to data structures must be activated before they can be used in transactions or reports.

  Missing Dependencies: Sometimes, the structures depend on other objects
