Use the Purchasing>Purchases module. Select the documents that are ordered and waiting to be purchased with the lightning button on the top right corner.
Double click the records in the selected order to carry them to the purchasing folder. In this step, the process is the same as purchasing. Use the pause order option, changing the order status only if the stock item will be waited for.
Afterwards, update the purchase and close it as an invoice or dispatch note. If the purchasing order is pending, don’t mark the close purchasing order option.
