Hi all, can't find the answer to this anywhere- if I have Sales Orders set to 'Order by Order Priority' will it also be sorted by date? Meaning if I have 2 sales orders with the same priority level, then the older one would be fulfilled first?

Did you figure this out? I had the same question.

I did not. Wasn’t able to get any information on setting up Order Priority unfortunately so I’ve had to hack around it with custom fields

Without considering the other preferences which affect allocation, it should go by which order was created first when two orders have the same priority (i.e. internal id/date created)
