The invoice update quantity is less than the quantity of matched product receipt. The inventory cost of the items will be understated.

We have two recipt

receipt1, item A, quantity : 5

receipt2, item A, quantity : 5

If my user open invoice with

itemA Quantity : 10 ( matched with receipt1 and receipt2 )

Then he changed the value to 5

itemA Quantity : 5 ( matched with receipt1 and receipt2 )

System shows warning

“The invoice update quantity is less than the quantity of matched product receipt.
The inventory cost of the items will be understated.”

he click post this invoice already.

After that we realized that this is wrong.

itemA Quantity : 5 ( should be matched with receipt1 only )

How to solve this problem ?? I try to cancel PO, but the button is disabled.
