We received a PO today and the amount received shows up in the transaction listing and in the RQTY field in both BKAPOL and BKAPHPOL .  The QC field in both files is 0.The UOH field in BKICMSTR is 0 and UOH in IN-A is 0.  There was no WO attached to the PO so the item was not received into WIP.  Anyone know what could have happened and what I should do to fix it?

UOH in BICLOC was 0.  This is a new item so there was no inventory before the PO was received.  I ran SM-J-C last night and reconciled UOH to the inventory transactions.  That resolved the inventory issue but it would be nice to know why this happened.
