Allow Negative Amount on Purchase Order - Change order Line
Our customer has a business requirement where they create purchase order for a supplier. The PO is a long term Purchase Order delivered by Supplier over a period of time. PO has multiple milestones (distributions) and is paid as per the milestone or % completion of milestones and as advance payments.
We have a business requirement where the requirements change during time, due to feasibility or change in design and accordingly the price also changes. This change is recorded in the application as change order on PO and goes through approval process and finally after approval the PO is updated (original line is impacted or a new PO line is added) as per the business case. This is easily done in the application if the change amount is positive.
