Split payment in the Scheduled Payments tab (Invoice workbench)

 

According to literature we can select an invoice and choose the Scheduled Payments tab. Then if we want to partially pay an invoice that has only one scheduled payment, we can choose Split to break the scheduled payment in two. This way we can place one of the lines on hold, while leaving the other free for payment.

 

My question is: How do we manage this process if for instance I received only one unit but the supplier billed us for 2. If I create the invoice for 2 units I will get a Qty Rec. hold after validation.

How do create the invoice, validate it, split the payment in two, place a hold on one line and pay the other line for one unit?
