Answer 1

parameters: p_vari type slis_vari.
at selection-screen on value-request for p_vari.
  perform alv_variant_f4 changing p_vari.
form alv_variant_f4 changing l_vari type slis_vari.
On F4 for layout selection - Get laouts created to this report.
  data: l_variant type disvariant.
  l_variant-report   = sy-repid.
  l_variant-username = sy-uname.
  call function 'REUSE_ALV_VARIANT_F4'
    exporting
      is_variant = l_variant
      i_save     = 'A'
    importing
      es_variant = l_variant
    exceptions
      others     = 1.
  if sy-subrc = 0.
    l_vari = l_variant-variant.
  endif.
Create a structure
data: wa_layout type disvariant.
fill up the layout with selected fields.
wa_layout-report = sy-repid.
wa_layout-username = sy-uname " Choose this if you want user specific
wa_layout-variant = p_vari.
Assign the same to the REUSE_ALV_GRID_DISPLAY
it is a import paramter  IS_VARIANT = wa_layout.
All you have to do is first execute the report and save layouts what exactly you want
and then next time you run the report you will get a chance to select the layout of your own.
or
You can get rid of MANDT field from fieldcatalog and internal table by creating a new
structure. I mean, if you know you always want to display the field from 2 to 11 then simply
delete the field from fieldcatalog.
You can assign to different field catalog using Field symbols and change your internal
table as well since you have created a dynamic internal table.
