If the field is obligatory then you must enter values otherwise it throws an error

you only need this:

AT SELECTION-SCREEN.

IF r1 EQ 'X' AND
p1 IS INITIAL.
==> error message
ENDIF.

your original logic can be simplified (however you get the error message, when p1 is empty and you switch from r1 to r2):

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    CHECK screen-group1 EQ 'A'.
    CASE 'X'.
      WHEN r1.
        screen-required = 1.
      WHEN r2.
        screen-required = 0.
    ENDCASE.
    MODIFY SCREEN.
  ENDLOOP.

Don't declare the parameter field as mandatory ..

But

at selection-screen output.

IF R1 = 'X'.

loop at screen.

if screen-group1 = 'A'.

screen-input = 0.

MODIFY SCREEN.

endif.

if screen-name = <parameter name>

screen-required = 'X'.

modify screen.

endif.

endloop.

ENDIF.

IF R2 = 'X'.

loop at screen.

if screen-group1 = 'A'.

screen-required = 0.

MODIFY SCREEN.

endif.

if screen-name = <parameter name>

screen-required = ' '.

modify screen.

endif.

endloop.

ENDIF.
