    SELECT
    coalesce((`rawmat_pallet_ag`.`sheets_pallet` * `rawmat_pallet_ag`.`outs_pallet`),0) AS agpcs,
    coalesce(((`rawmat_pallet`.`no_pallet` * `rawmat_pallet`.`sheets_pallet`) * `rawmat_pallet`.`out_pallet`),0) AS printedpcs,
    coalesce(`rawmat_pcs`.`quantity`,0) AS rawpcs,

    rawmaterial.rawmaterial_code AS rawmaterial_code,
    rawmaterial.rawmaterial_desc AS rawmaterial_desc,
