Order Entry Invoice duplication was a classic problem in ACCPAC Plus if any of the workstations or server had Opportunistic Locking Enabled. Historically you had to disable OpLocks or this type of error would occur, typically with data corruption as well. DataCare, if setup correctly, should detect any OE database problem.

By default new workstations and servers come with OpLocks enabled and historically disabling OpLocks was a must. It's possible that at this time you have a mix of some Enabled and some Disabled, which could result in this issue. Definitely a mix of some enabled and some disabled is going to create some kind of problem.

None of my other clients are experiencing this issue and no one else has reported it on this forum so its safe to say that this has something to do with you hardware/network environment. Let me know if you would like us to assist you with tracking this down.
