hi, it has found that purchase order quantity is showing in negative in purchases by supplier detailssome purchase orders are fine and some are showing in negative

The transaction types that show a negative quantity in the report are supplier credits and inventory starting values. It's possible that the bill was converted from a purchase order. In this case, the bill's quantity will not show a negative value, but the amount may be affected. This can happen if the invoice was created before the purchase order, or if the items were oversold.

To identify and resolve negative quantities, click on the transaction showing the negative quantity to identify the cause, then correct it accordingly.
