反查BOM, 找出它的上阶

查询物料的上阶方法有三:

1. CS15 可直接查出物料的上阶直至顶阶物料.

2. CALL FUNCTION. 只能查上上阶, 要想得到顶阶, 需要递归查询.

CS_WHERE_USED_MAT Bills of material; where-used list

CS_WHERE_USED_MAT_ANY Bills of material; where-used list as material or class item

3. 根据表 STAS 和 STPO.

REPORT  z_af_023.

DATA: BEGIN OF iwultb OCCURS 0.
        INCLUDE STRUCTURE stpov.       " BOM Item
DATA: END   OF iwultb.

DATA: BEGIN OF iequicat OCCURS 0.
        INCLUDE STRUCTURE cscequi.   " BOM Explosion: Equipments
DATA: END   OF iequicat.
*
DATA: BEGIN OF ikndcat OCCURS 0.
        INCLUDE STRUCTURE cscknd.    " BOM Explosion: Sales Order
DATA: END   OF ikndcat.
*
DATA: BEGIN OF imatcat OCCURS 0.
        INCLUDE STRUCTURE cscmat.    " BOM Explosion: Materials
DATA: END   OF imatcat.

DATA: BEGIN OF istdcat OCCURS 0.
        INCLUDE STRUCTURE cscstd.    " BOM Explosion: Standard Object
DATA: END   OF istdcat.

DATA: BEGIN OF itplcat OCCURS 0.
        INCLUDE STRUCTURE csctpl.    " BOM Explosion: Equipments
DATA: END   OF itplcat.

SELECTION-SCREEN BEGIN OF BLOCK bk1 WITH FRAME.
PARAMETERS: i_werks LIKE marc-werks.
PARAMETERS: i_matnr LIKE marc-matnr.
SELECTION-SCREEN END OF BLOCK bk1.

START-OF-SELECTION.

  DATA: datub LIKE rc29l-datub,
        datuv LIKE rc29l-datuv.

  CALL FUNCTION 'CS_WHERE_USED_MAT'
    EXPORTING
      datub                      = datub
      datuv                      = datuv
