A number of our clients have had a similar experience.

We think the problem started when the Next Fiscal Year process was run. I believe that this is when the "Opening balance or a Closing amount in a Prior Year, the Current Year or Next Year" entries are generated by GL 9.x, based on the Account Type, at that time.

This is notably different from Accpac Plus for DOS, which did not have the improved benefits of a Soft Year-end, but only used this setting when the "Close Year Function" was run. Personally, I would like to see Adagio display a warning when "Create Next Fiscal Year" is selected. After all, historically, for MANY years, Accpac Plus for DOS users have checked the Account Type as part of the Year End Process immediately prior to running the "Close Year" function.

If this is your first Year-end with the wrong Acct Types, you might be able to unpost the GL Batches posted after the "Create Next Fiscal Year" process was run, Restore from the prior Backup, Correct the Account Type, Create your Next Year and Repost the Unposted Batches accordingly.

Hope this helps, good luck!
