abap - 带有 SELECT-OPTION 的 BDCDATA

Question

我打电话给报告CALL TRANSACTION。我不想使用SUBMIT. 我需要为SELECT-OPTIONS打开按钮提供值并排除 value 'X'。这是我从注册中找到的代码

  ls_bdcdata-fnam     = 'BDC_OKCODE'.
  ls_bdcdata-fval     = '=%020'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-dynbegin = 'X'.
  ls_bdcdata-dynpro   = '3000'.
  ls_bdcdata-program  = 'SAPLALDB'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-fnam     = 'BDC_OKCODE'.
  ls_bdcdata-fval     = '=NOSV'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-fnam     = 'BDC_SUBSCR'.
  ls_bdcdata-fval     = 'SAPLALDB                                3010SCREEN_HEADER'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-dynbegin = 'X'.
  ls_bdcdata-dynpro   = '3000'.
  ls_bdcdata-program  = 'SAPLALDB'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-fnam     = 'BDC_OKCODE'.
  ls_bdcdata-fval     = '=ACPT'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-fnam     = 'BDC_SUBSCR'.
  ls_bdcdata-fval     = 'SAPLALDB                                3030SCREEN_HEADER'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

  ls_bdcdata-fnam     = 'RSCSEL_255-SLOW_E(01)'.
  ls_bdcdata-fval     = 'X'.
  APPEND ls_bdcdata TO lt_bdcdata.
  CLEAR ls_bdcdata.

SELECT-OPTIONS由_

ls_bdcdata-fval     = '=%020'.

但是当我SELECT-OPTIONS在被调用的报告中添加一个新的时，这个数字发生了变化。我可以从名称SELECT-OPTIONS而不是这个'=%020'值中获得数值吗？因此，当我添加新的 SELECT-OPTIONS.
