Note: my code is found between the start or selection and end of selection

Answer 1

That is the normal behaviour for warning messages issued in START-OF-SELECTION (as already suggested, check the documentation).
If you want your program to issue a message and continue running (for example the behaviour of the status message) yet show it like a Warning message, you can use the DISPLAY LIKE addition (only in newer releases):
START-OF-SELECTION.
  MESSAGE s000(oo) WITH 'test' DISPLAY LIKE 'W'.
  WRITE sy-uzeit.
