at the procedure creation time i set Default schema to - STUDENT.
Your calling statement should contain "STUDENT" instead of _SYS_BIC as you set student as the default schema.
Also you will find the procedure under the Student Schema.
If you have more than 1000 objects (which is very common), right click on the Schema name and click Filter.
Did you create your procedure using the extension .procedure or .hdbprocedure?
