How to Restrict the users from changing the Default variant of report.

Question

Hello everybody,
The requirement is to restrict the users to save and overwrite  the default layout variant (Layout for higher managenet)set for the report, but at the same time they should be able to change and save the other layouts for which they are having access.
I have written the logic in the program which is working fine for all the scenario when we execute the report. But the logic doesnt work if the user is selecting the layout on the output screen of the report.
for e.g if the user runs the report using the layout varaint for which he is having the authorization then he gets the all 4 options so he then he can select the layout for which he is not authorized and he can overwrite.
i have debugged and check as i have found that after the report output is shown all the layout paramater is controllled by the statndard SAP objects.
Can anyone help me out in this issue.
Thankyou in advance.
*to get the default layout variant.
  w_save = 'A'.
  if p_vari is initial.
    clear disvariant.
    disvariant-report = sy-repid.
    w_variant = disvariant.
    call function 'REUSE_ALV_VARIANT_DEFAULT_GET'
      exporting
        i_save     = w_save
      changing
        cs_variant = w_variant
      exceptions
        not_found  = 2.
    if sy-subrc = 0.
      p_vari = w_variant-variant.
    endif.
  endif.
*logic to check user authorization to change the layout setting.
  if p_vari = c_layout.
    if not sy-uname is initial.
      select single * from agr_users
              where agr_name = c_role
              and   uname    = sy-uname.
      if sy-subrc = 0.
        w_save = 'A'.
      else.
        w_save = ' '.
      endif.
    endif.
  endif.

Hi Maine,
Thanks for your reply.
As you mentioned for your own program, you can control the parameter "I_SAVE", when calling "REUSE_ALV_GRID_DISPLAY".
so already i have use the same logic and control the parameter through I_SAVE and here i am calling method ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY instead of "REUSE_ALV_GRID_DISPLAY".
and it works fine when we execute the report but the logic doesnt work when the user tries to change and save the layout variant on the output screen of the report.
