ALV edit_mask 控制:为输出编辑掩码

例子为ALV中合作伙伴代码显示为描述的例子,负号前提的话只需修改se37中的function.

DATA: lw_fcat_1012 TYPE lvc_s_fcat.
  CLEAR gt_fcat_1012.
  CLEAR lw_fcat_1012.
  lw_fcat_1012-fieldname = 'PARVW'.
  lw_fcat_1012-ref_field = 'PARVW'.
  lw_fcat_1012-ref_table = 'ZYWDLR_HZHB'.
  lw_fcat_1012-edit_mask = '==ZPARVW'.
  lw_fcat_1012-scrtext_s = lw_fcat_1012-coltext
                         = lw_fcat_1012-scrtext_m
                         = lw_fcat_1012-scrtext_l
                         = '伙伴功能'.
  lw_fcat_1012-intlen = 8.
  lw_fcat_1012-outputlen = 8.
  APPEND lw_fcat_1012 TO gt_fcat_1012.

在se37建function

FUNCTION conversion_exit_zparvw_output.
*"----------------------------------------------------------------------
*"*"Local interface:
*"  IMPORTING
*"     REFERENCE(INPUT)
*"  EXPORTING
*"     REFERENCE(OUTPUT)
*"----------------------------------------------------------------------

  IF input IS NOT INITIAL.
    SELECT SINGLE vtext FROM tpart INTO output
      WHERE parvw = input
*      AND spras = sy-langu
      .
    IF output IS INITIAL.
      output = input.
    ENDIF.
  ENDIF.

ENDFUNCTION.
