OPEX can create a Purchase Order for all items provided by a Supplier.
Navigate to Purchase Orders > Suppliers
Select a supplier to see the items they provide, use the Build Purchase Order command to create a Purchase Order for all the items from this supplier. You will need to provide a Budget Code and Warehouse for the Purchase Order.
The Qty for each item will be determined by the Order Gap column (Order Gap is the current Position - the Reorder Level), if the qty is positive then the qty will be set to 0 otherwise the qty will be the positive value of Order Gap.
The newly created PO can be viewed on the main PO grid. The Qty can be modified as required and lines can be added to or deleted.
