Today I came across a situation where the "Spreadsheet" option was missing while right-clicking on an ALV generated using REUSE_ALV_GRID_DISPLAY.
(See below)
I went through couple of discussions on this topic but most answered the missing "Export" option in Application bar (List> Export> Spreadsheet)
Observed that in my case, I could view the "Spreadsheet" option via from Application bar.
The Internal table declaration is as below-
* TYPES-----------------------------------------------------------------
types : begin of ty_output,
kbeln type kbeln,
begru type begru,
bstat type bstat,
end of ty_output.
**--Internal Table----------------------------------------------------
Data: it_outtab type standard table of ty_output.

Logic for fetching data
..
* Display the data in grid
call function 'REUSE_ALV_GRID_DISPLAY'
exporting
i_callback_program = sy-repid
is_layout = rec_layout
it_fieldcat = li_fldcatlog[]
i_default = 'X'
i_save = 'A'
is_variant = g_v_variant
tables
t_outtab = li_output.
While debugging, found that the internal table 'li_output' had a deep structure 'BSTAT'.
The types declaration was updated as below-
The Internal table declaration is as below-
* TYPES-----------------------------------------------------------------
types : begin of ty_output,
kbeln type kbeln,
begru type begru,
bstat type wrfbstat, "<<<<<-
end of ty_output.
**--Internal Table----------------------------------------------------
Data: it_outtab type standard table of ty_output.
Post the code change, the 'Spreadsheet" Option appeared.
Documentation on REUSE_ALV_GRID_DISPLAY didn't mention about not using "Deep structures", though.
Hope this will be helpful for others!
