This function is used to display a change master or an engineering change request. Different authorization checks take place before you can display this data.

The system checks the authorization object C_AENR_BGR (authorization object for activities and authorization group). Activity 03 controls the functions for displaying a change master. If you try to display a change object from a processing function for the change master, the system also checks whether you are authorized to display the chosen change object (such as bill of material or document).
