Overriding account category assignments (AC/BR/GM)
When you create an activity group, you must assign an account category structure to it (except GL-only activity groups). If you need to override the parameters set in the category structure/activity group assignment, you can assign account category characteristics to individual posting activities. Use this procedure to make those assignments.
After you create the first assignment, you can copy account category assignments using Activity Copy (AC110) or Account Category Copy (AC115) to reduce the total time required for maintenance.
