If ArtCode is increased in INVc definition to more than 20 characters, I presume it must be changed to the same length in every other register which has an item field?
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
