REUSE_ALV_GRID_DISPLAY (column headings from ALV to EXCEL) Max please help

Question

Hi Max,
If you remember in one of my last post I asked for changing the column headings in ALV display for example from 'Material' to 'Material used'.
I am using
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
   EXPORTING
      I_CALLBACK_PROGRAM                = repid
      IT_FIELDCAT                       = field_body
      I_SAVE                            = g_save
      IS_VARIANT                        = g_variant
      IT_EVENTS                         = events
    TABLES
      T_OUTTAB                          = itab.
And you suggested me the following way....
loop at field_body into field_wa.
case field_wa-fieldname.
  when 'Material'.
     field_wa-seltext_l = 'Material used'.
     field_wa-seltext_m = 'Material used'.
     field_wa-seltext_s = 'Material used'.
endcase.
modify field_body from field_wa.
endloop.
It is working well. In ALV display the column heading is changed to what I wanted. But the question is when I export the displayed ALV to Excel using ALV functionality, Export->Spreadsheet... I see that <b>I dont get the Column Heading into Excel as it was in the ALV display.</b>
I get in the Excel as 'Material u' or 'Mat. Used'. But when I add this line in the code.....
when 'Material'.
     field_wa-seltext_l = 'Material used'.
     field_wa-seltext_m = 'Material used'.
     field_wa-seltext_s = 'Material used'.
    <b> field_wa-outputlen = 20.</b>
Then I see that I get the complete heading in the Excel. But this way the columns with outputlen 20 are taking much space in ALV display.
Is there any fix for this. May be not mentioning the outputlen but still get the column headings into Excel as it was in ALV display.
Anyone with ideas please respond. Waiting for replies. Thanks

Hi
The labels have a fixed size:
seltext_l is long   text: 20 char
seltext_m is medium text: 15 char
seltext_s is short  text: 10 char
The text 'Material used' is long 13 char so you should write:
field_wa-seltext_l = 'Material used'.
field_wa-seltext_m = 'Material used'.
field_wa-seltext_s = 'Mat. used'.
You can try to set the field colwidth_optimize of parameter IT_LAYOUT.
This field should optimize the width of the colunm
So
data layout type SLIS_LAYOUT_ALV.
layout-colwidth_optimize = 'X'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = repid
IT_LAYOUT   = layout       
IT_FIELDCAT = field_body
I_SAVE = g_save
IS_VARIANT = g_variant
IT_EVENTS = events
TABLES
T_OUTTAB = itab.
and you can decide which label has to be used:
field_wa-seltext_l = 'Material used'.
field_wa-seltext_m = 'Material used'.
field_wa-seltext_s = 'Mat. used'.
If you want to set the short text
field_wa-ddictxt   = 'S'.
...medium
field_wa-ddictxt   = 'M'.
...long
field_wa-ddictxt   = 'L'.
