How can i manipulate Filter for a free characteristic?

Question

Hello,
I have an report with free characteristic 0material.
When the user restricts values for 0material, the report should add value "#" automatically whatever the user selects.
Example:
Material: aa123, aa124,aa125, #.
when i filter:
aa123 --> query: aa123+#
aa124 --> query: aa124+# and so on.
i'm trying to do this with user exit for global variables but i'm not beeing sucessfull.
Any ideia?
Thanks a lot,
Regards,
Maria

Hi,
What i want is:
if the user input is M001 then ABAP should convert it as M001,#
If the user input is M001, M002 then ABAP should convert it as M001, M002,#
If the user input is M001, M002, M003 then ABAP should convert it as M001, M002, M003,#
is like M001 or M002.
i tried with several options and nothing works.
Last change:
Only 1 one variable with Changeable with Query Navigation function active and user input not active.
ABAP code:
    IF i_step = 2.
      CLEAR loc_var_range.
      loc_var_range-vnam = 'VAR1'.
      loc_var_range-iobjnm = 'INFOOBJECT'.
      loc_var_range-sign = 'I'.
      loc_var_range-opt = 'EQ'.
      loc_var_range-low = '#'.
      APPEND loc_var_range TO i_t_var_range.
    ENDIF.
This is still not working. I executed the query in debug and i notice that table i_t_var_range does not have the new entry with # in step 3.
Am i doing somethign wrong?
Thanks
