ALV Edit Mask isn't applied when exporting as "Spread Sheet".

Question

Hi all,
One of our program has "Edit Mask" as XXXXX____ for displaying data in ALV (Mask first 5 numbers as X, display last 4 numbers as it is).  However, when data is exported as "Spread Sheet", the edit mask is not applied.  Does anyone know how to force edit mask when data is exported as SpreadSheet (MHTML)?  If you export as "local File" and then do "SpreadSheet", the edit mask works.. it is just when the direct "SpreadSheet" done, it doesn't work. 
(i.e. CL_GUI_ALV_GRID->EXPORT_TO_SPREAD_SHEET doesn't apply EDIT Masks set in Field Catalog.)
Here is more technical info.  We are on ECC 6.
Field Catalog is of type LVC_T_FCAT.
for a specific field, "EDIT_MASK" is set to XXXXX____.
The ALV is called using
My_ALV_CLASS->SET_TABLE_FOR_FIRST_DISPLAY
exporting
is_layout = My_layout
is_toolbar_excluding = my_toolbar_exclude
changing
it_outtab = My_data_table
it_fieldcatalog = MY_FIELD_CATALOG_DEFINATION_WHERE_EDIT_MASK_IS_SET
exceptions...
Thanks in advance!

Hello,
This is first time I am giving an answer.
Instead of using a function module to merge the field catalog, try doing it one by one.
for example,
pt_fieldcat-col_pos = 01.
pt_fieldcat-fieldname = 'KUNNR'.
APPEND pt_fieldcat.
pt_fieldcat-col_pos = 02.
pt_fieldcat-fieldname = 'IP'.
pt_fieldcat-edit = 'X'.
pt_fieldcat-edit_mask = '-.-.-.-'.
APPEND pt_fieldcat.
and use the structure Z_IPADDR in method parameters instead of a function.
CALL METHOD go_grid_ip->set_table_for_first_display
EXPORTING
     i_structure_name = 'Z_IPADDR'
     it_toolbar_excluding = lt_exclude
     is_layout = ls_layout
CHANGING
     it_fieldcatalog = pt_fieldcat
     it_outtab = p_t_auth_ip.
CALL METHOD go_grid_ip->set_ready_for_input
EXPORTING
i_ready_for_input = 1.
and also you can use following function module to check if the edited value is still in ALV or not
CALL METHOD grid->check_changed_data
    IMPORTING
      e_valid = l_valid.
  IF l_valid IS NOT INITIAL.
then the edited data in alv is successfully changed in internal table behind that.
Debugging may find you an answer.
