Hello,
I have a requirement that to sorting lines on pick list by item priority. Note: not by location priority. That is , supposing item A with priority 1, which is highest, item A would become the first line on pick list no matter what locations item A are stocked.
It is not too difficult on 1 warehouse situation. I just add a field on stock item screen to let user set 1 to 100. And sorting on pick list by this user field.

However, if the instance has multiple warehouses, and these warehouses might have different priorities on items. That would make things complicated.
A workable way I can think out of is such I add multiple fields on stock item, 1 field for 1 warehouse. And for different warehouses, using an independent pick list form which sorted by different priority field.
It can be a way to fulfill the need, but it is not quite smart. Can somebody give me a talent idea? Thank you in advance.
