Backdating the Item Valuation report relies on a complete inventory transaction history, because the amounts as of a date are calculated from the current values plus/minus the values from history. If history is ever purged, or OE/PO Day End (or anything else that writes to inventory history) has not been run, or any transaction history data value is wrong for any reason, then this will throw off the results of a backed Item Valuation report (or Stock Card report).
Yes, we have had a couple of people tell us the Item Valuation report isn't correct, in the past. We made these two fixes to Adagio Inventory 8.1C (2011.07.13):
- The back-dated Item Valuation reports was incorrect for items where receipt adjustments had been posted in Purchase Orders for Adagio. In addition, a receipt adjustment with a quantity increase and cost adjustment posted in Adagio Inventory was also incorrect (receipt returns were correct). The item valuation report was adding cost when it should be subtracted. This caused the back-dated Item Valuation reports to be incorrect for the item.
- When a receipt entered in Adagio Inventory was adjusted to change the cost (but not the quantity), a receipt adjustment record was not posted to the transaction history file. This caused the Transaction History and back-dated Item Valuation reports to be incorrect for the item. It has been corrected but the back-dated Item Valuation report will continue to be incorrect for the item.
Since you indicated that the client is using version 8.1D, you'll need to first determine that the Item Valuation report is correct without using the backdating option. If it is correct, then you'll need to determine whether all the historical transactions (related to particular items) are correctly in IC since the last month end is run. Note that the second fix mentioned above is related to an incorrect value written to IC History, thus backdating the report will result in different values than the report when printed live back on the month end date.
Currently, there are no known problems with the results of backdating the item valuation report, provided the data is complete and correct.
