如何使用CS_BOM_EXPL_MAT_V2获取BOM爆炸的正确数量的组件？

Question

我的程序出了问题。我正在使用功能模块CS_BOM_EXPL_MAT_V2来获取材料的BOM。例如，我有一个具有ff的材料MAT1。 BOM爆炸。

MAT1
- COMP1 with Qty 2
- COMP2 with Qty 1
- COMP3 with Qty 1

然后，对于组件COMP1，它还有子组件：

COMP1
- SUBCOMP1 with Qty 1
- SUBCOMP2 with Qty 1

因此，我在我的程序中使用CS_BOM_EXPL_MAT_V2期待的是报告的数量为SUBCOMP1 = 2和SUBCOMP2 = 2（因为MAT1使用2个数量的COMP1）。但我得到的是SUBCOMP1 = 1数量和SUBCOMP2 = 1数量，因为我认为它只考虑COMP1的BOM和COMP1的数量没有考虑在内。

当运行事务CS12时，对于材料SUBCOMP1，输出是正确的（SUBCOMP2 = 2，MAT1 = 2）。

那么，我如何使CS_BOM_EXPL_MAT_V2工作，以便它将尊重组件的计数，在这种情况下COMP1与数量2，并将值级联到子组件，在这种情况下SUBCOMP1和SUBCOMP2，并将其相乘以便它将返回正确的数量，在这种情况下，两个子组件应该具有Qty 2，如事务CS12？

如果使用FM CS_BOM_EXPL_MAT_V2无法做到这一点，请提供其他方法来实现此目的。

这是我的FM目前的样子：

CALL FUNCTION 'CS_BOM_EXPL_MAT_V2'
  EXPORTING
    aumgb                 = 'X'
    capid                 = 'PP01'
    datuv                 = v_datuv "date input in selection screen
    endhl                 = '1'
    mehrs                 = 'X'
    mmory                 = '1'
    mtnrv                 = v_matnr "material input in selection screen
    stlal                 = v_stlal "alternative BOM input in selection screen
    stpst                 = 0 "Level in multi-bom expl.
    svwvo                 = 'X'
    werks                 = v_werks "plant input in selection screen
    vrvso                 = 'X'
  IMPORTING
    topmat                = gs_top
  TABLES
    stb                   = gt_stb
    matcat                = gt_matca
  EXCEPTIONS
    alt_not_found         = 1
    call_invalid          = 2
    material_not_found    = 3
    missing_authorization = 4
    no_bom_found          = 5
    no_plant_data         = 6
    no_suitable_bom_found = 7
    conversion_error      = 8
    OTHERS                = 9.

这是Laurent Fournier在snc.sap.com上给出的答案。这对我很有帮助，因此我想在此保留它。

I think that you must set multilevel indicator. Take a look at the following code and see if this can help you.

FORM EXPLODE_BOM  USING U_DATE
                        U_MATNR
                        U_MENGE
                        U_WERKS
                        U_MULTI
                CHANGING   C_SUCCESS.

  CLEAR : C_SUCCESS.
