We are testing with AX Retail POS and I have found that if a transaction is returned before it's posted to core AX from the POS, a sales order is created in core AX with negative quantity.
For example: I created a transaction in the POS with 1 line item and paid it in full with cash. Seconds later I returned the item. Next I created a statement in core AX Retail, expecting to see two transactions pulled from the POS. Instead there was only one transaction and that was the returned amount. Therefore when you post the statement it creates 1 sales order with 1 negative line.
My conclusion is that if you create a transaction in the POS and return it before it can be synced with core AX than the sales order it creates is wrong. It only shows the amounts for return lines which means your general ledger accounts should be off. You never show that you originally paid the customer and your crediting the customer back for the return.
Can someone confirm this either is wrong or explain why it would be correct?
