We were getting an error message AA 116 while running prerequisite report for S/4 Hana Asset Accounting migration. We resolved this issue by adding new depreciation area with group currency. However is there a way we can keep new depreciation area suppressed/deactivated as it is not needed by us. In case we keep it as deactivated we are getting an error while creating new assets. In case we activate it we will have to run Tcode-AFBN which is throwing error related to exchange rates that too for 80's & 90's which is not present in the system. Our company code was live in 2014 with some assets acquired 80's.
