ROLLLBACK and COMMIT transaction issue in SSIS package - ssis

Question

I am trying to do a ROLLBACK and COMMIT transaction in SSIS package.The commit transaction is working fine.For the rollback transaction i inserted null value to a column which's data type is money.Here iam getting an error in DFT and Commit SQLtask.Please give me a solution,
I changed the CONTROLLFLOW properties--->TransactionRequired to Required
In DFT TransactionRequired---->Supported
Please help me friends
Thanks in advance
The errors are shown below

Either enlist this session in a new transaction or the NULL transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

You are missing two approaches with SSIS and transaction handling. If you are using SSIS native transactions (setting TransactionRequired=Required), you do not need to call Rollback. Transaction will be rolled back automatically if an error will occur or you deliberately set an error. Important thing to notion - transaction scope, i.e. when it will commit. My recommendation - declare transaction on dedicated Sequence Container; transaction will be committed when leaving this Sequence Container.
If you want to use transaction handling with SQL Commit and Rollback, you do not use TransactionRequired=Required. It is a special case for MS SQL, for details see The implementation of Transaction with out msdtc in the design pattern and TransactionOption in SSIS.
