I ran JC-M for transaction date range for March and ran my GL WIP account balance and the numbers are not even close.   I have never been exact but I've never been off by this much.  11k.  Could WIP not be calculating correctly?  We just finished a big job that was very labor and material intensive.  
 
Any suggestions on why this would happen?  
 
I also checked my IN-F Inventory Value by class and compared it to my GL accounts for finished goods and raw materials and they are only off by $100.  So I don't think it is the WIP materials that are off.

Yes I posted before running them.

I think I found part of the problem back in Feb WIP was adjusted to JC-M Transaction dates 2-1 thry 2-29 for R and C.  Some the C's had balances and which I believe to be because they were not closed until March and the adjustment to "balance" has made it even farther off.
 
When I run "as of a prior date" of 3/31/08 with "Actual Finish Date" 4/1/08 (only because it won't let me bypass it) it balances.  I tested it by running the GL WIP account for all the open WO and totaled the dr/cr and exported it to excel and the $ Net WIP along with WIP Variance matches.
 
So it basically JC-M should always be run with "as of a proir date" (month end) and all "transaction dates" left blank for part RF and "actual finish date" is the first day of the next month.
