Simple User Exit (I don't understand..)

I want to test simplest User Exit:

1. I found with CMOD - SUSR0001 User exit after logon to SAP System with function module EXIT_SAPLSUSF_001 Customer-Specific Check After Every User Logon:

FUNCTION EXIT_SAPLSUSF_001.

INCLUDE ZXUSRU01.

ENDFUNCTION.

2. I created ZXUSRU01

3. I added simplest code:

----

• INCLUDE ZXUSRU01 *

----

WRITE 'HELLO FIRST USER EXIT!'.

4. I saved and activated ZXUSRU01

5. I tryed to test. I logoned several times and I didn't see anything. I didn't see 'HELLO FIRST USER EXIT!'.

Please tell me, how can I see 'HELLO FIRST USER EXIT!'?
