Trigger complied, but can not insert any record. 
 table is mutating, trigger/function may not see it

How can I solve it. Please suggest.

Sorry again. Thanks to ***mat and all* for helping me**.
I have understood. 
Here my new code after correction.

the code erro ORA-04091 is relative the transaction. In a trigger you dont can execute select, unless you declare a new transacation with clause PRAGMA AUTONOMOUS_TRANSACTION.

remember to run a commit or rollback to finalize transaction on the trigger.
