I had a feeling this would be the response! As far as MSi being involved, they say they don't have much luck getting Sage's assistance and wanted us to get the ball rolling. I don't think they really know much about sData, but neither do I - ugh! At this point I'm trying to figure out where to go next and thought we'd check here on the off chance someone might know more that us. I just got off a call in which the client said that he was able to enter an order in Service Pro that created the Sage SO successfully, then he tried entering another order in Service Pro for the same customer and the integration bombed out. BUT, when he rebooted his workstation, that second order went through without error. This would happen a few times and then it would error out again. Their IT suggested checking firewall settings, but any other ideas about that strange development? Of course everything seems to be inconsistent.
