SM30里DEC数据显示0

需求：DEC数据在维护的时候显示0

1，设置数据元素对于的域带转换历程、

2，写转换历程函数(注意两个历程的输入和输出类型，这个需要修改)

FUNCTION conversion_exit_zdays_input.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     VALUE(INPUT) TYPE  CLIKE
*"  EXPORTING
*"     VALUE(OUTPUT) TYPE  ZECRM_DEC
*"----------------------------------------------------------------------
  IF input = '0' OR input = ''.
    output = '0'.
  ELSE.
    TRY .
        output = input.
      CATCH cx_sy_conversion_no_number.
    ENDTRY.
  ENDIF.

ENDFUNCTION.

FUNCTION conversion_exit_zdays_output.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     VALUE(INPUT) TYPE  ZECRM_DEC
*"  EXPORTING
*"     VALUE(OUTPUT) TYPE  CLIKE
*"----------------------------------------------------------------------

  IF input = '' OR input = '0'.
    output = '0'.
  ELSE.
    output = input.
    CONDENSE output NO-GAPS.
  ENDIF.

ENDFUNCTION.

效果：
