how to use at selection-screen event for a set of input fields?

Here is an example. You should use the BLOCK functionality.

report zrich_0001 .

parameters: p_parm1 type c,
            p_parm2 type c.

selection-screen begin of block b1.
parameters: p_datum1 type sy-datum,
            p_datum2 type sy-datum.
selection-screen end of block b1.

at selection-screen on block b1.

 if p_datum1 is initial
  and p_datum2 is initial.
   message e001(00) with 'Enter at least one date'.
 endif.
