Interesting error today with MAS200. I was trying to run the MRP report and on a couple workstations I was receiving an Error 65 SY_SESSION.PVC Line 4513. Nothing listed on Sage KB. I resolved it by renaming the sy_workstation.m4t file in MAS_SYSTEM folder. This seems to be a new fix_all for station specific stuff. Thought I would pass it on. MAS200 V4.40.0.4 sidenote they were a 3.71 to 4.40 upgrade a couple months ago
