Displaying messages in BEx with i_step = 3

Hello all,

we used to display messages  for wrong user entries by using exit variables in exit EXIT_SAPLRRS0_001 and this function module:

    CALL FUNCTION 'RRMS_MESSAGE_HANDLING'
      EXPORTING
        i_class  = 'ZCO05'
        i_type   = 'E'
        i_number = '102'
        i_msgv1  = l_d_yearmonth_to
        i_msgv2  = l_d_yearmonth_tvarvc.
    RAISE wrong_value.

But this isn't working anymore with the new exit BAdI RSROA_VARIABLES_EXIT_BADI. The replacement

RAISE EXCEPTION TYPE cx_rs_error.

for

          RAISE wrong value.

only prevents the output of the report but doesn't displays the above message. I also tried CX_RS_ERROR_WITH_MESSAGE and CX_RSB_GUI_ERROR_WITH_MESSAGE - with no luck!

Is there a solution for this issue?

Best regards, Martin
