Message no. AA660 in ABAA
I'm facing an error AA660 during posting of unplanned amortization for an asset saying that transaction value in area 31 (local area) contradicts NBV rule. I found references to this error in a lot of SCN threads, but each time the answer boiled down to changes in the settings for particular area in OADB (suggestion being to put "All values allowed" for NBV rule).
Technical side of the issue is ok, but the trouble is why should the asset NBV be negative after posting of unplanned depreciation at all? Asset value in 31 area at the end of the June (by the way, it's also end of fiscal year) equals to appr. 1.500.000,00 RUB, unplanned amortization equals appr. 180.000,00 RUB. So how can the NBV be negative? Could you please advise me what is the logic for calculation of NBV in such cases and how to get rid of the message without modifying NBV rule?
P.S. Some details:
- asset is purchased on 15.06.2015;
- start of depreciation in area 01 - 01.06.2015;
- start of depreciation in area 31 - 01.07.2015.
- unplanned amortization posting date - 30.06.2015;
- depreciation methods - all linear.
