It will set everything to "Q" and put all on hand stock into the default bin per warehouse.  You can then use WC-B to reset items you do not want to control at the Q level back to Y or N and WC-C to redistribute on hand stock into multiple bins if needed for the items you are keeping at Q level control.

Why can't I update the BIN OH with WC-C? Sometimes it will go to that field and lots of time it won't.
I'm in a situation where I need to control the quantities in the separate bins.

I did that but it still bypasses the BIN OH field. Could it be that there's only one amount of 200 on hand?
What happens if I receive more? They are manually updated with INV-C and not done with a PO.

Lynn,
I don't know and cannot find my notes on the utility to use. I remember running it last year but can't find it on any menu today.
Please refresh my memory.
BTW is there a list of the utilities that can be run and what they do?
Thanks,
Liz Odell
