Minus Sign in front

Question

Hello all,
I have a requirement where in I need to bring the minus sign in front for the amount field in ALV Grid Display.
I used the FM CLOI_PUT_SIGN_IN_FRONT, but after I pass back the values, the sign gets set at the end. Moreover, I cannot create a character filed because the business might want to do sum on it.
Please advice.
Regards,
Salil
P.S. the below piece of code
DATA : gv_bill_rev  TYPE string,
         gv_balance   TYPE string.
  LOOP AT gt_master INTO gs_master.
    gv_bill_rev = gs_master-bill_rev.
    gv_balance  = gs_master-balance.
    CLEAR : gs_master-bill_rev,gs_master-balance.
    CALL FUNCTION 'CLOI_PUT_SIGN_IN_FRONT'
      CHANGING
        value = gv_bill_rev.
    CALL FUNCTION 'CLOI_PUT_SIGN_IN_FRONT'
      CHANGING
        value = gv_balance.
    MOVE : gv_bill_rev TO gs_master-bill_rev,
           gv_balance  TO gs_master-balance.
    MODIFY gt_master FROM gs_master INDEX sy-tabix
                                    TRANSPORTING bill_rev balance.

You can directly specify an edit mask for output.
Field EDIT_MASK in the field catalog is a 60 character field in which you can specify an edit mask.
fieldcat-edit_mask = 'V___.__'
The V at the left indicates that you want the sign to appear at the left.  The _ will be replaced by the values of the number.  Put as many underscores as required.  You may also want to specify commas (,), if desired, for thousand's separators and a period (.) for the decimal point, if needed.
Alterntively, if an appropriate conversion exit exists to put the sign in front, you can assign the conversion exit in the field catalog table.
Field CONVEXIT in the field catalog can be used to specify the name of the conversion exit.
