Now, let me add to that advise. As she has pointed out, if you have posted an SOP Invoice and if it involves an Inventory Item, it’s a thumb rule that we must pass a Return.
Return does the following:
1. Returns Inventory Items to our Stock.
2. Returns Serial / Lot Numbers for the respective Item as well.
3. Reduces also the Customer Receivables.
4. Passes a reverse GL.
So your Inventory is correct, Receivables is correct & is your GL.
