I am incredibly new to AX (new job in which the system is used) and am not technical (i.e coding etc) so please excuse my offensive naivety!
I have situations where vendors delay ex factory dates for multiple PO's. No one in the business is aware of a process where you can update multiple PO's with new ex factory dates. Is this possible? Please see the below screenshot which I hope explains my issue better than the above!
That delivery date option is a customisation, as is a lot of that screen :-) Can you select edit in grid, which opens up a screen with them all listed and then change the delivery date going down header by header? Depends in part on your workflow triggering and controls, and what that customisations does.
