Cyndee,
This has been happening to me for the last 3 month's and I can't get the issue resolved. For me it's "F" type items and I narrowed it down to happening when using the "convert sales orders to work orders" routine. It's gotten so bad that I had to create a crystal report to compare the BKICLOC records to transaction records and item master records so that I can keep on top of it.
For the time being I add the part(s) back to the location file with IN-L-B (this will fix the IN-A screen - eg SO's, WO's etc) then need to edit the newly created BKICLOC record for the actual units on-hand.
Hope this helps....
It's been frustrating me for a while now.......
