Has anyone notice that Charge (Item) affects COGS in prior accounting periods. I closed and produced financials for the month of November a couple of days into December. Just last week I reran the financials for November and noticed that my net income has changed. I discovered that it was a purchase invoice with Charge (Item) that caused this problem. I had received in a freight invoice that I was assigning to a purchase receipt. I assume the change in COGS occurred because the system is trying to allocate the additional charge to inventory which has already been sold to a customer. I understand the logic. The problem I am having is that this adjustment shouldn't affect closed accounting periods. In other ERP systems that I have used, the system will apply this additional charge to "cost variance' GL account on the income statement based on the posting date. So my question is how do i stop Business Central from messing up periods that are closed.
