In my company the PO and Migo is created by the engineers team and MIRO is done by Accounts team, the problem is while doing PO engineer's picking the wrong the GL so everytime its becoming an issue. Is there any option to disable the GL picking at the time of creating PO and it should be selected at the time of processing MIRO?
For the PO related to material, the GL are picked automatically based on GL Assignment in OBYC. So i think that should not be an issue for you.
For services related PO, there is also an alternative, in which the GL can be picked up automatically based on material group entered in the PO. The below blog by dev.patra should help you set it up
Hope this helps.
Thanks & Regards
