Sometime in the past 3 weeks, the Cost of a single Inventory Item changed, and the change impacted all historical transactions in QBD, including transactions in closed accounting periods. A thorough search of "item cost change" reveals that this absolutely should never have happened. Per everything I can find, changing the Cost of an Item should impact future transactions ONLY.
Additionally, we cannot figure out how or when the Cost was changed on the Item detail. It should be $0, and until recently, it was. A few months ago we duplicated our Company File in order to create a sandbox to work in. The sandbox file shows the Cost of this item at $0, and all historical transactions have a $0 impact on COGS and Inventory accounts. The Cost change was clearly recently, and it changed previous transactions, to the point of impacting Financial Reports that have already been used to file taxes (!).
So here are my questions:
1. How can I find out who changed the Cost of the Item and when?
2. How did the Cost change manage to impact historical transactions??
3. How can I prevent this happening in the future?
Thanks for any help,
(I'm sorry my name really is) Karen
