Considering MEA market, here projects are executed mainly for internal / investment purposes where organizations, execute projects like construction / renovations projects. Mainly at the time of invoice, it is a kind of percentage completion against the PO line items and finally making receiving on completion for PO. before that they get into many kind of requirements like creation of completion certificate for Invoice/ making percentage milestone payments to the vendor applying retentions, Delay penalties, advance settlements, and performance bond guarantee amounts.

either line level prepayment option should be provided for this purpose or there should be option to create Vendor invoices on percentage completion of milestones from PMA module.
