1、自定义函数

FUNCTION CONVERSION_EXIT_Z0002_OUTPUT.
*"--------------------------------------------------------------------
*"*"局部接口：
*"  IMPORTING
*"     REFERENCE(INPUT)
*"  EXPORTING
*"     REFERENCE(OUTPUT)
*"--------------------------------------------------------------------

*  IF INPUT IS NOT INITIAL.
*    WRITE INPUT TO OUTPUT.
*    OUTPUT = OUTPUT * 100.
*    CONCATENATE OUTPUT '%' INTO OUTPUT.
*    CONDENSE OUTPUT NO-GAPS.
*  ENDIF.
  "负号及百分比
  DATA: OUTPUT1(20)  TYPE C,
        OUTPUT11(30),
        OUTPUT2(30),
        OUTDATUM(16) TYPE P DECIMALS 2.
  IF NOT INPUT IS INITIAL.
    OUTDATUM = INPUT.
*    IF INPUT > 0.
    IF OUTDATUM > 0.
      OUTDATUM = OUTDATUM  * 100.
      WRITE OUTDATUM TO OUTPUT1 ."RIGHT-JUSTIFIED .
      OUTPUT11 = |{ OUTPUT1 }%|.
    ELSE.
      OUTDATUM = OUTDATUM * ( -1 ) * 100.
      WRITE OUTDATUM TO OUTPUT1 ."RIGHT-JUSTIFIED.
      OUTPUT11 = |- { OUTPUT1 }%|.
    ENDIF.
  ELSE.
    CLEAR OUTPUT1.
  ENDIF.
  CONDENSE OUTPUT11 NO-GAPS .
  WRITE OUTPUT11 TO OUTPUT2 RIGHT-JUSTIFIED .
  OUTPUT = OUTPUT2.
  CLEAR: OUTPUT2.

ENDFUNCTION.

2、可以每次使用函数转换，也可以如果只是ALV显示的话 结合ALV参数使用

但是要注意函数名称格式是固定的，CONVERSION_EXIT_XXXX_OUTPUT，其中XXXX可以自己起名字

结合ALV的参数
