How do I figure out exactly what is preventing Item Merge Utility from working?

SOLVED

I have several items that I need to merge, but every time I try to run the Delete and Change Items Utility I get the error message, "You cannot proceed with unposted data in IM Transaction entry."  I have confirmed that I do not have any open IM Transaction Entry Batches and the IM Daily Transaction Register comes up as "The file is empty."  Invoicing and Purchase Order Receipts have been posted for the day.  So I don't know what is preventing me from running this utility.  We actively use the Work Order Module, so could it be this module that is holding things up?  The message clearly states that there is supposedly unposted data in the IM Transaction entry.  Is there a flag I can reset?  Maybe a report I can run?  Not having the ability to use this merge function is a real inconvenience!  Any help would be appreciated.  We are running Sage 100 Advanced ERP 2013 (Version 5.00.4.0)
