Impossible to generate information message with 'RRMS_MESSAGE_HANDLING'

Question

Hello
I would like to generate Informative message once the variable screen is available for user entry.
The message from FM (see code beloe) is generated once the query result is up.
IF step = 2.
CALL FUNCTION 'RRMS_MESSAGE_HANDLING'
EXPORTING
I_CLASS = 'ZBW'
I_TYPE = 'I'
I_NUMBER = '022'
If put RAISE no_REPLACEMENT  then execution stops and system generates an error.
Thanks

Hi,
Use the following Code, don't write in between Case and EndCase, after ENDCASE you write code for I_STEP = 3.

          LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE WHERE VNAM = 'MONTH'.
