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
*"----------------------------------------------------------------------

*  CALL 'CONVERSION_EXIT_ALPHA_INPUT'  ID 'INPUT'  FIELD INPUT
*                                      ID 'OUTPUT' FIELD OUTPUT.

IF INPUT = '0' OR INPUT = ''.
  OUTPUT = '0'.
ENDIF.

ENDFUNCTION.

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

*  CALL 'CONVERSION_EXIT_ALPHA_INPUT'  ID 'INPUT'  FIELD INPUT
*                                      ID 'OUTPUT' FIELD OUTPUT.

IF INPUT = '' OR INPUT = '0'.
  OUTPUT = '0'.
ENDIF.

ENDFUNCTION.

效果：
