There are three different ways to achieve this.
1.Add a Return to Vendor, and return the incorrectly priced stock. Then repurchase the stock with the correct price.
2.If you cannot add a Return to Vendor as the stock has been sold, add a negative expense PO, or an expense PO, and link to the original PO. This will reduce/increase the COGS on the original PO. The negative PO expense will reduce/increase all the stock records on the PO by the selected disperse option. This will not work if not all the stock requires pricing to be amended.
3.If not all stock records are to be impacted by price fix, add a further negative expense PO, or expense PO to produce either a credit, or further invoice in the creditor’s account. The stock on the original PO will not be impacted, and the costs on these purchases will not be correct.
