BAPI\ U SALESORDER\ U CHANGE不进行更改

我接到电话了 BAPI BAPI\销售订单\更改 要更新销售订单并需要在物料级别更改edatu,BAPI的返回是销售订单已更改但未进行更改。

我在给BAPI打电话后就开始了 BAPI BAPI\销售订单\更改 但这些变化并没有影响到数据库。

 ls_header_x-updateflag = 'U'.

  assign ls_schdl to <schdl>.
  assign ls_schdlx to <schdlx>.
  assign ls_items to <items2>.
  assign ls_itemsx to <items2x>.

  <schdl>-itm_number = '000010'.
  <schdlx>-itm_number = '000010'.

  <schdl>-sched_line = '0001'.
  <schdlx>-sched_line = '0001'.

  <items2>-itm_number = '000010'.
  <items2x>-itm_number = '000010'.

  <schdlx>-itm_number = '000010'.
   <schdl>-dlv_date = '20181111'.

  append <schdl> to lt_schdl.

  <schdlx>-dlv_date = 'U'.
  <schdlx>-updateflag = 'U'.
  append <schdlx> to lt_schdlx.

  <items2x>-updateflag = 'U'.
  append <items2> to lt_items.
 append <items2x> to lt_itemsx.

      return           = lt_return
      schedule_lines   = lt_schdl
      schedule_linesx  = lt_schdlx.

  read table lt_return assigning <return> with key type = 'E'.
