OSP quantities getting doubled

[LeLeux@xxxxxxxxxxxx]

Hello everyone!

We have a process here that we just discovered doubles the quantities for 
Operations that are OSP's.
The doubling impacts transactions found in MOTRAN & information found in 
MAPICS PCC Job Screen.

On our routers we have specific workcenters that identify OSP's, and there 
will be a PO for the process.
When the parts return from the vendor Receiving clocks ON the OP, then 
after they pass Inspection they
clock OFF the OP reporting the quantity good.  The OFF transaction 
populates MOTRAN.
After we receive an invoice (a week or so later) from the vendor, AP will 
create a batch to apply cost to the
Operation.  This process creates PCC transactions that when posted created 
an additional OFF transaction
in MOTRAN that doubles the reported quantity.  This impacts mfg job 
summary screens as well.

I'm not sure I detailed the process well enough, but I'm hoping some one 
recognizes the process
and has a suggestion.  I searched the Midrange archives but did not find 
anything.  I also used
MAPICS's website with out results.  I plan to pose the scenario to MAPICs, 
but I was hoping to
get better insight from the board!

I appreciate any insight or comments, thanks in advance!
