We are looking for the table that contains the Pick Slip Header Pick Status.

I looked at inv_txn_request_headers, however the only distinct value in the entire table is the value '7' and we definitely have pick slips in both Confirmed and Open statuses, so 7 must refer to something else. I also looked at the table INV_PICK_SLIP_NUMBERS, but the status column here does not appear to correspond to Open/Confirmed statuses.
