matching the column b(sku)c(count)with A

[sammc2]

I need to match to the same row the B sku and the C qty to the same sku
in row A. not all sku in b will be in A. I need this so I can get the
counts in qty lined up on the same row as A for all the sku that exist
in A. ATOZ is A ... prod is B and the qty is C.
