I want to create an activity report (notification) for a piece of equipment which was installed at a location 2 years ago. This equipment has since moved to a different location. How do I get SAP to relate the activity report to the location the equipment was in two years ago and stop it reverting back to its current day location.
I have tried changing the activity report reference dates and notification dates but it still defaults the reference object information back to today's location.
Any ideas?

First why do you want to create a backdated notif? Did you entere the old functlocation?

Why?
To record in SAP the reason for failure of a pump. There is an order in SAP already for this failure but the history notification was note created at the time.
Did I enter the old functional location number? The functional location still exists but there is a different pump (equipment) now installoed at that location. I wish to refer to the pump that was installed at that location back in Feb 2002.

Before I used SAP for maintenance management, I use database to keep failure history, after 1997 my database can convert to SAP. please discuss with your IT or SAP admin.

I think is easier to document that failure at a new notification (with todays date) and explain at the description the the failure ocurred on X date in the past and it was corrected with order number 123. Then complete (NOCO) the notification.
