We have a mix of customers. Some are happy with peoples names as PO's, some want PO numbers, some don't care, some want PO numbers all the time and to ignore what the owners/directors say when buying things.
It would be nice when setting up a customer to have a tick box that comes up with what ever message you tie to that box and customer i.e. Must have a PO, and wont let you proceed unless you click OK.
As a follow up to this, it would be nice to have the "Customer PO No." box being able to be selected on a customer by customer basis to have an entry before it can be processed, similar to "Salesperson". If "Salesperson" is not selected the quote/invoice cant be processed.
In both cases this would have to be customer by customer not a global setting.
