Quite recently I installed Encumbrance Management module through Add/Remove Programs menu in Dynamics GP 2010 R2 DVD. The installation was simple and fine. I ran utilities and logged into to Dynamics GP using sa. It logs me in successfully however parallel to the login process, the error below is surfaced.
Microsoft.Dynamics.GP.Online services.dll: The type initializer for Microsoft.Dexterity.Applications.root threw an exception.InnerException: parameter name ProductID.
I did a Repair on Dynamics GP 2010 R2. I logged back. The error didn’t' surface again. The cause of the error is unknown though I know it is due to Dynamics GP online services.
