There is a scenario where a purchase receipt reversal is prohibited by the workflow as it would cause negative product quantity on hand i.e. insufficient QOH. This could have resulted by intervened sale shipments between the product purchase receipt#1 and the attempted reversal.
To circumvent this you would need to
Create a stock quantity adjustment to increase the product QOH
Ensure that the stock adjustment is backdated to the receipt date of purchase receipt#1
Reverse the purchase receipt#1. Again ensure that the reversal is backdated to the intended reversal date
Create a new purchase receipt#2 to reflect/replace the original purchase receipt#1
Use the Copy button in the ribbon to create purchase receipt#2 from #1
- Create a second stock quantity adjustment to decrease the product QOH by the quantity specifies in the new purchase receipt#2
