    Hello,
    I want to write an update query for the following :
    Table A :
    Field ARTID QTY
    Table B
    Field InventID, ArtID, QTYProgram, QtyStock
    I want to write an update query which update Table A field QTY with the difference from QtyStock - QtyProgram for the same ARTID and where InventID is a parameter.
    Is there anyone who can help me?
    Thanks in advance
    Ralph
