I know this is an old post but wanted to ask something related to this.
I have the same problem, I can't find the allocation. I have ran the SQL script to find all allocations and still can't find it. I have executed Check Links on everything and still can't find it. When I look at table IV00102, I can see the records for that part number with ATYALLC with the incorrect qty. After updating both records, when I run the inventory reconciliation, GP adjusts it back to the wrong qty. Any other place that I should look?
Thanks
