IDCNACCTBLN 增强实现负号提前

1.转换例程函数

CONVERSION_EXIT_ZSIGN_OUTPUT

FUNCTION conversion_exit_zsign_output.
*"----------------------------------------------------------------------
*"*"本地接口：
*"  IMPORTING
*"     REFERENCE(INPUT)
*"  EXPORTING
*"     REFERENCE(OUTPUT)
*"----------------------------------------------------------------------
  DATA:  output1(20),
         output2(20),
         outnum(16) TYPE p DECIMALS 2.

  IF input IS NOT INITIAL.
    outnum = input.
    IF input >= 0.
      WRITE outnum TO output1.
    ELSE.
      outnum = outnum * ( -1 ).
      WRITE outnum TO output1.
      CONCATENATE '-' output1 INTO output1.
    ENDIF.
  ELSEIF input = '0.00'.
    WRITE outnum TO output1.
  ENDIF.
  CONDENSE output1 NO-GAPS.
  WRITE output1 TO output2 RIGHT-JUSTIFIED.
  output = output2.
  CLEAR : output2.

ENDFUNCTION.

2.增强

2.1 alv的汇总和明细输出，负号提前增强
