How to create Alternative BoM using CSAP_MAT_BOM_MAINTAIN function module

[srikanth_d4]

Hi,

I am using FM:CSAP_MAT_BOM_MAINTAIN to create alt BoM, i could not able to create an alt BoM using this fm its giving error msg as:

T ID NUM MESSAGE E 29 037 BOM already exists for ZPRD-HEAD1 5001 4

I am passing:

I_MATERIAL=ZPRD-HEAD1

I_PLANT = 5001

I_BOM_USAGE = 1

I_ALTERNATIVE= 4

I_VALID_FROM = 10/27/2017

I_STKO = 2 EA 00

FL_COMMIT_AND_WAIT = X

I_FL_CAD I_FL_BOM_CREATE =X

I_FL_NEW_ITEM = X

I_FL_DEFAULT_VALUES = X

TABLES

T_STPO passing 3 components

please help me to get it resolved.

Regards,

Srikanth

i had some problems into using that FM to create an alternative too.

i switched to the old CS_BI_BOM_CREATE_BATCH_INPUT1: maybe not the best solution, but it works pretty fine and fast.

The FM CSAP_MAT_BOM_MAINTAIN will never create alternative BOM (except 01) because there is a flag inside flg_no_alt_create always X

This flag is not in the parameter of the fonction but fixed to X

  call function 'CS_DI_HEADER_OBJECT_CHECK'
    exporting
      ecsin                    = csin
      flg_foreign_key          = kreuz
      flg_ale                  = flg_ale
      flg_api                  = kreuz
      flg_cad                  = fl_cad
      flg_no_cad_rules         = flg_no_cad_rules
      flg_no_standard_val      = strg-locvl
      flg_item_single_read     = flg_item_single_read
      flg_no_change_doc        = fl_no_change_doc
      flg_no_alt_create        = kreuz

Should be great if SAP let us the control of this flag as a parameter..

I have found, checked and coded a solution with the following function : BAPI_MATERIAL_BOM_GROUP_CREATE(already existing in ECC SAP Version)

It can create BOM with several alternatives !

It is working well !!  

  CALL FUNCTION 'BAPI_MATERIAL_BOM_GROUP_CREATE'
    EXPORTING
      testrun           = lv_bapiflag
      all_error         = 'X'
    TABLES
      bomgroup          = it_bomgroup
      variants          = it_variants
      items             = it_items
      materialrelations = it_matrel
      itemassignments   = it_itemas
      return            = it_return.
