Excluding buttons for REUSE_ALV_POPUP_TO_SELECT

Hello:

I'm fighting to get function codes to remove all buttons but one from REUSE_ALV_POPUP_TO_SELECT. I wish to leave only the "Copy" Button.

I know how to do that:

DEFINE m_excluding.

ls_excluding-fcode = &1.

append ls_excluding to lt_excluding.

END-OF-DEFINITION.

DATA: lt_excluding TYPE slis_t_extab.

m_excluding '&ETA'. "Pick

m_excluding '&OUP'. "Sort ascending

m_excluding '&ODN'. "Sort desdending

m_excluding '&ILT'. "Filter

m_excluding '&OL0'. "Field disposition

m_excluding '%SC'. "Find

m_excluding '%SC+'. "Find +

Then passing lt_excluding to the FM REUSE_ALV_POPUP_TO_SELECT.

What I don't know are the Function Codes for Select All, Unselect All and Cancel.

I tried unsuccessfully with

m_excluding '&ESC'. "Cancel

m_excluding '&F12'. "Cancel

m_excluding '%ESC'. "Cancel

m_excluding '%F12'. "Cancel

m_excluding '&ALL'. "Select all

m_excluding '&SAL'. "Unselect all

¿Where can I find the function codes for Select All, Unselect All and Cancel?

¿Does anybody know these Function Codes?

Thanks in advance
