Problem with WCF-SQL adapter to executed a stored procedure while using transaction block in stored procedure

Hi all,
        I am using WCF-SQL adapter to call a stored procedure from BizTalk Server, Inside the Stored Procedure I have used Transaction block to insert some data into a table and it’s not working. But on removing transaction block the insert operation get works.
Is there any limitation in WCF-SQL adapter not use Transaction block inside the stored procedure?
Kindly help me on this
