Global variable value becomes null across procedures in a package body

Hi ,

Facing a strange issue today .Global variable value becomes null across procedures in a package body . g_request_id printing blank in the procedure p1 .

Any guess ? Is something wrong in the database ?

create or replace package body xyz as

g_request_id NUMBER;

procedure P1 is

dbms_output.put_line ('g_request_id ='||g_request_id);

end p1;

Procedure p2 is

g_request_id :=1234;

p1;

end p2;

end xyz;
