Manage transactions in multiple stored procedures

Hi

I have two stored procedures A & B. Stored procedure B is calling from A. I want to implement the transaction in such a way that, if any error happened in A, all the operations from A should be rolled back but all the operations done by B should be committed.

See the scenario below.

Procedure A

Begin Transaction

Begin Try

          Do some oprations (Operations 1)

          Call procedure B (Operations 2)

           Do some error operations

        Commit transaction

End Try

BEgin Catch

        Rollback Transaction

End Catch

In the above scenario the Operations 1 should be rolled back and Operations 2 should be committed in procedure B.

Is it possible to implement this scenario ?

Thanks in advance.
