We are using Version 2005.1 3/25/06 update. We are behind a few updates.
We run IN-F for "all except 0 value parts" for our purchased parts several times a week and compare it to our raw inventory GL account to make sure things are working OK. Occasionally if the $s are not the same we will print out the GL transactions and IN-N-A for the same period of time and cross reference them until we find the transaction that doesn't have a match and correct the problem.
Several weeks ago we had a difference of about $12,000 that we can't figure out. When we compare all of the transactions in the GL (GL-C) to the transactions from IN-N-A we have a match for them all, but still are off the $12,000. ANY ideas on how we can find this difference?
 
Thanks

Just a thought, but you may want to inquire whether any purchased part numbers were changed during the period from a type "R" to a type "N" or to type "F".  N (non-inventory) types do not appear on IN-F, and "F" types appear on IN-F list for finished goods, rather than purchased parts.
