Help Needed: t_stpo-mat_provis Not Updating in BOM Using 'CSAP_MAT_BOM_MAINTAIN'

Hello,

I americium presently utilizing the BAPI 'CSAP_MAT_BOM_MAINTAIN' to update a BOM. However, erstwhile adding values to the BOM, the worth successful t_stpo-mat_provis does not look to beryllium reflected successful the BOM.

The logic I americium utilizing is arsenic follows:

CALL FUNCTION 'CSAP_MAT_BOM_MAINTAIN'
        EXPORTING
          material           = material
          plant              = plant
          bom_usage          = bom_usage
*         ALTERNATIVE        =
*         VALID_FROM         =
          change_no          = change_no
*         REVISION_LEVEL     =
          i_stko             = i_stko
*         FL_NO_CHANGE_DOC   = ' '
          fl_commit_and_wait = 'X'
*         FL_CAD             = ' '
          fl_bom_create      = 'X'
          fl_new_item        = 'X'
*         FL_COMPLETE        = ' '
*         FL_DEFAULT_VALUES  = 'X'
*         FL_IDENTIFY_BY_GUID       = ' '
*         FL_RECURSIVE       = ' '
        IMPORTING
          fl_warning         = fl_warning
          o_stko             = o_stko
        TABLES
          t_stpo             = t_stpo
*         T_DEP_DATA         =
*         T_DEP_DESCR        =
*         T_DEP_ORDER        =
*         T_DEP_SOURCE       =
*         T_DEP_DOC          =
*         T_DOC_LINK         =
*         T_DMU_TMX          =
*         T_LTX_LINE         =
          t_stpu             = t_stpu
*         T_FSH_BOMD         =
*         T_SGT_BOMC         =
        EXCEPTIONS
          error              = 1
          OTHERS             = 2.

Is determination thing I mightiness beryllium missing oregon immoderate further parameters that I should include?

I would greatly admit your assistance.
