> ✅ This process explains how to change the Purchasing Unit of Measure for a selected Product in Frameworks.
> ✅ 
> ✅ <span style="color: #003366">First the system checks to see if average costing is being used. If it is being used and outstanding purchase orders exist then you are not allowed to change the purchasing UOM. If average costing is being used and there are no outstanding purchase orders then the purchasing UOM can be updated.</span>
> ✅ 
> ✅ <span style="color: #003366">If standard costing is being used then the purchasing UOM can be updated. After you have selected to update the purchasing UOM it is applied to all open purchase orders, credit notes, sales orders, debtor credits, quotes and CPF Requisitions within the system (holding the line sell on the sales orders and quotes where stock has been sold in the purchasing UOM to prevent rounding / repricing anomalies). Debtor sales type transactions (sales orders, quotes and debtor credits) are updated where a product has been sold / quoted in the purchasing UOM and the purchasing UOM is not equal to that product's stocking / selling UOM.</span>
