Creating a purchase order from a quotation can be completed from the quotation page and there is no need to go to Expenses > Purchase Orders. There are steps to make the transaction as follows:

Step 1: Go to Revenue > Quotation > See all

Click All then select the item that you want to create a purchase order.

Step 2: When PEAK successfully shows the quotation then go to Options > Select the Dropdown button > Create Purchase Order.

When you already complete the transaction, PEAK will show you the menu for creating the purchase order as shown in the image below. Next step, you can create the purchase order.
