以下是 oracle sql 语句，表述了取数逻辑，各表之间的关系，如用abap来写稍作修改即可.
--取订单行的已发货数量
select
vp2.vbeln,
vp2.posnr,
sum(va2.RFMNG)rfmng
from sapsr3.vbap vp2
inner join sapsr3.vbfa va2 ON va2.VBELV = vp2.vbeln AND va2.POSNV = vp2.posnr and ( va2.VBTYP_N = 'T' or va2.VBTYP_N = 'J' ) --找到相应的交货单
inner join sapsr3.vbup vu on vu.vbeln = va2.VBELN and vu.posnr = va2.POSNN and vu.WBSTA = 'C' --交货单已完全交货
group by vp2.vbeln, vp2.posnr
