If you want to get the values of the double click row then you can use below things.
If you are using Function module to display the ALV then you have to give the form name
to the import parameter user command of these function module and then implement this as
FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
RS_SELFIELD TYPE SLIS_SELFIELD.
CASE R_UCOMM.
WHEN '&IC1' " double click event
here you can use the variable RS_SELFIELD where you will get the PO number and po item
where you have clicked and then you can call your function module
CALL FUNCTION 'ME_DISPLAY_PURCHASE_DOCUMENT'
EXPORTING
I_EBELN = clicked po number
I_EBELP = clicked po item
I_ENJOY = 'X'
EXCEPTIONS
OTHERS = 1.
or else you can use set parameter id and call trasaction and skip first screen.
endcase.
endform.
or
Else if you are using the ALV class then declare one local class with method dpoble clickas
class ...
method on_double_click for event double_click of cl_salv_events_table importing row cloumn.
endclass.
and also set event handler using
set handler event_handler->on_user_command for gr_events(object of cl_salv_events_table)
and then implement the event handling class and write the logicas written in case R_UCOMM as above.
