Step One: Add a manual work order line

Step Two: From the Purchases Assistant screen, mark the part as "Ordered" from the vendor you paid. This will create a Purchase Order. Mark the ordered lines as Received

From the Purchases Assistant screen, select the white line and click the "Order" button

Assign the vendor that you used when creating the Invoice and click Save. Close out of the Send PO screen that opens next. 

Your line will now show as yellow "Ordered, Not Received". 

Select the yellow line and click the Receive button at the bottom.

Your line will now be "Received, Not Invoiced". Make note of the PO number on the green lines, you will use this in the next step. 

Step Three: Edit the invoice to attach the Purchase Order line

Select the blue Invoiced line and click the "Invoice" button to open the AP Invoice. 

We will change the distribution lines to assign the PO lines from the estimate. 

First, key the PO number at the top middle of the invoice screen and select the "Received" button. This will load your received lines for that PO. Edit the "Act List" and "Act Cost" as needed (note, the total of the Costs will need to match the invoice total or you will not be able to save). Click the green check button to set the lines. 

Second, remove the placeholder line that you added when creating the original invoice by selecting it and clicking the red "-" icon. 

When the sum of your PO lines matches the Invoice Cost, you will be able to save. 

When you refresh your Purchases Assistant screen, your line will now be attached to a PO. Reject and return the line as needed.
