Hi, is there a problem with the Reference Number sorting in Production Order? or is it my computer problem?
What edition and version of Manager are you using?
This appears to be a bug (Desktop version 22.1.72)
By default the order is descending by date
and when sorted by reference (ascending or descending) the numbers are treated as text not numbers. I think this is an old bug which has resurfaced see
Fixed in the latest version (22.1.87)
