We recently did an upgrade to GP2010 for one of our clients and thought I would let everyone know of a bug we found in GP2010. The bug occurs when processing payroll. If your posting options are set to create a journal entry per batch what will happen is that you will end up with an unbalanced journal entry. It appears that all of the distributions are created but some distribution lines don’t include values for all of the employees in that payroll run.
If your posting options are set to create a journal entry for each transaction than the posting is fine. Microsoft has confirmed this to be a bug and a fix should be included in SP1 of GP2010.
