ABAP根据字段汇总

Posted 2023-03-11

ABAP里我想要根据某个或某几个字段汇总：具体是我ALV里面物料相同，供应商相同，就是需求量不同，我想相同的物料、相同的供应商，需求量也随之合并，怎么实现，求解。。。谢谢各位！！

把 供应商 物料号 需求量放到一个内表里面。然后把数据汇总
例如 你把所有的数据都放到了一个内表GT_ITAB里面
然后定义个内表
DATA: BEGIN OF GWA_TEMP,I LIFNR LIKE LFA1-LIFNR
MATNR LIKE MARA-MATNR,
MENGE TYPE P.
END OF GWA_TEMP.

LOOP AT GT_ITAB INTO GWA_ITAB,
LWA_TEMP-LIFNR = GWA_ITAB-LIFNR,
LWA_TEMP-MATNR = GWA_ITAB-MATNR,
LWA_TEMP-MENGE = GWA_ITAB-MENGE.
COLLECT LWA_TEMP INTO LT_TEMP
ENDLOOP.

就OK了 参考技术A 只能在ALV外面处理数据，然后把处理好的数据放进ALV 参考技术B *---type pools
TYPE-POOLS: slis.
*---internal tables
DATA: BEGIN OF it_flight OCCURS 0,
carrid LIKE sflight-carrid,
connid LIKE sflight-connid,
fldate LIKE sflight-fldate,
seatsmax LIKE sflight-seatsmax,
seatsocc LIKE sflight-seatsocc,
END OF it_flight,
*--internal tables for alv
it_fieldcat TYPE slis_t_fieldcat_alv,
wa_fcat LIKE LINE OF it_fieldcat,
layout TYPE slis_layout_alv,
it_sort type slis_t_sortinfo_alv,
wa_sort like line of it_sort.
*---start-of-selection .
