如下所示情况：

BAPI传值如下所示

    CALL FUNCTION 'BAPI_SALESORDER_CHANGE'
      EXPORTING
        salesdocument    = gs_head-vbeln
        order_header_inx = ls_h_inx
      TABLES
        return           = lt_return
        order_item_in    = lt_item_in
        order_item_inx   = lt_item_inx
        schedule_lines   = lt_schedule
        schedule_linesx  = lt_schedulex
        conditions_in    = lt_conditions_in
        conditions_inx   = lt_conditions_inx
        extensionin      = lt_extensionin.

其中lt_conditions_in / lt_conditions_inx 传入更新价格条件的值

        lt_conditions_in = VALUE #( BASE lt_conditions_in
                                    ( itm_number = ls_item-posnr
                                      cond_type  = 'ZPR0'
                                      cond_value = ls_item-zkbetr
                                      currency   = ls_prcd-waers ) ).

        lt_conditions_inx = VALUE #( BASE lt_conditions_inx
                                    ( itm_number = ls_item-posnr
                                      cond_type  = 'ZPR0'
                                      updateflag = 'U'
                                      cond_value = 'X'
                                      currency   = 'X' ) ).

上述赋值代码导致价格条件重复。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

为了解决重复的条件类型，实现代码段如下：

        lt_conditions_in = VALUE #( BASE lt_conditions_in
                                    ( itm_number = ls_item-posnr
                                      cond_st_no = ls_prcd-stunr
                                      cond_count = |{ ls_prcd-zaehk ALPHA = IN }|
                                      cond_type  = 'ZPR0'
                                      cond_value = ls_item-zkbetr
                                      currency   = ls_prcd-waers ) ).

        lt_conditions_inx = VALUE #( BASE lt_conditions_inx
                                    ( itm_number = ls_item-posnr
                                      cond_st_no = ls_prcd-stunr
                                      cond_count = |{ ls_prcd-zaehk ALPHA = IN }|
                                      cond_type  = 'ZPR0'
                                      updateflag = 'U'
                                      cond_value = 'X'
                                      currency   = 'X' ) ).

即：传值的时候，必须传入原条件类型对应的字段值cond_st_no 和cond_count

上述两个字段的取值来源：根据

VBAK-knumv =prcd_elements-knumv

and VBAP-POSNR = prcd_elements-posnr

从表prcd_elements中获取
