We have a scenario where we procure services (e.g. Software delivery) and this is then invoiced based on % completion (25%, 50%, 100%) or based on time (invoice for what's been done on a monthly basis, where the amount at that point in time is not predictable in advance)
So we'd raise a PO for a delivery of a service (e,g. 1 line, 'software component', cost 23,600k, quantity 1) and then when we receive an invoice need to call off a monetary amount. The delivery is a non-stock item (real world terms) if that makes any difference to how we might do config to achieve this.
Given the Purch Reqs are being raised by business users without detailed understanding of the Finance's system's quirks, is there any way to call off a monetary amount against a PO as opposed to against quantity received?
We're aware we could have a work around of always having quantity = 100 and calling off against this, but this makes for a more complicated Purch Req process for business users who then need to set their unit price as divided by 100 and a quantity of 100 just to meet a finance system quirk (or to raise POs with multiple lines to line up with anticipated invoice tranches, which aren't always set in stone).
Thanks for any guidance on this.
