Hi, I've spoken to support about this, but they haven't seen it reported, but they suggested I also check here. During any express upgrade I've done from 6.6 to 7.8, the past PO header file does not seem to get upgraded. None of the changes to the file are present, i.e. PO number is still a length of 6, PO numbers are not in separate fields, etc. The only thought I have on my end, is maybe some modification or larger record size is causing an issue. These are accounts we previously didn't support, so I'm not as familiar with them. I did notice a larger record size on POPAST then another 6.6 system I checked, but I also visually compared the file and didn't see any additional data present, but I may have missed something... Has anybody encountered this?? I did similar conversions to 7.7 and didn't have this problem...
