负号显示

最简单的一种：

CALL FUNCTION 'CLOI_PUT_SIGN_IN_FRONT'
      CHANGING
        value = value.

还有就是自己写函数等了

构建ALV的FIELDCATE时，设置 edit_mask = '==XXXXX',建立函数CONVERSION_EXIT_XXXXX_OUTPUT设置输出为负号提前，之后调用ALV显示函数，系统会自动调用函数CONVERSION_EXIT_XXXXX_OUTPUT




 




  FUNCTION CONVERSION_EXIT_ZMENGE_OUTPUT.




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




*"*"Local interface:




*"  IMPORTING




*"     REFERENCE(INPUT) TYPE  ANY




*"  EXPORTING




*"     REFERENCE(OUTPUT) TYPE  ANY




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




  OUTPUT = INPUT.




  CALL FUNCTION 'CLOI_PUT_SIGN_IN_FRONT'




    CHANGING




      VALUE = OUTPUT.




ENDFUNCTION.




 




1、建立自定义函数




1.1 整数显示




FUNCTION CONVERSION_EXIT_Z0002_OUTPUT.




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




*"*"Local interface:




*"  IMPORTING




*"     REFERENCE(INPUT)




*"  EXPORTING




*"     REFERENCE(OUTPUT)




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




  DATA: OUTPUT1(12)   TYPE C,




        OUTDATUM   TYPE INT4.




  IF INPUT <> SPACE.




    OUTDATUM = INPUT.




    if input > 0.




      move OUTDATUM TO OUTPUT .




    else.




      OUTDATUM = OUTDATUM_*( -1 ).




      move OUTDATUM TO OUTPUT1 .




      CONCATENATE '-' output1 into output.




      CONDENSE output NO-GAPS .




    endif.




  ELSE.




    OUTPUT = SPACE.




  ENDIF.




ENDFUNCTION.




1.2 浮点数显示




FUNCTION conversion_exit_zsign_output.




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




*"*"Local interface:




*"  IMPORTING




*"     REFERENCE(INPUT)




*"  EXPORTING




*"     REFERENCE(OUTPUT)




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




  DATA: output1(19)   TYPE c,




        output2(19),




        outdatum   TYPE p DECIMALS 2.




  IF  not input is initial.




    outdatum = input.




    IF input > 0.




      WRITE outdatum TO output1 ."RIGHT-JUSTIFIED .




      CONCATENATE ' ' output1 INTO output1.




    ELSE.




      outdatum = outdatum_*( -1 ).




      WRITE outdatum TO output1 ."RIGHT-JUSTIFIED.




      CONCATENATE '-' output1 INTO output1.




    ENDIF.




  ELSE.




*    output = '0.00'.




    CLEAR output1.




  ENDIF.




  CONDENSE output1 NO-GAPS .




  WRITE output1 TO output2 RIGHT-JUSTIFIED .




  output = output2.




ENDFUNCTION.




2、设置ALV输出格式字段格式




  clear ls_fcat.




  ls_fcat-fieldname = 'INT4'.




  ls_fcat-inttype   = 'I'.




  ls_fcat-intlen    = 10.




  ls_fcat-col_pos   = l_lin.




  ls_fcat-seltext_s = ls_fcat-fieldname.




  ls_fcat-seltext_m = ls_fcat-fieldname.




  ls_fcat-seltext_l = ls_fcat-fieldname.




  ls_fcat-edit_mask = '==Z0002'.




  append ls_fcat to ct_fcat.




3、调用函数就可达到负数符号前显的效果。




  call function 'REUSE_ALV_GRID_DISPLAY'




    exporting




      it_fieldcat                       = lt_fcat




    tables




      t_outtab                          = gt_outtab




    exceptions




      program_error                     = 1




      others                            = 2.




 




2.       


方法1：把字段设置为CHAR型，拼接字符串负号自然可以提前显示。


 


方法2：构建ALV的FIELDCATE时，设置 edit_mask = '==XXXXX',建立函数CONVERSION_EXIT_XXXXX_OUTPUT设置输出为负号提前，之后调用ALV显示函数，系统会自动调用函数CONVERSION_EXIT_XXXXX_OUTPUT
