TransactionOption In SSIS

I had a 3 simple packages get called from master package. First package populates time dimension (stored proc), second one populates transaction type dimension(stored proc) and the final one populates date dimension.

I set the TransactionOption = Required in the Master package, every thing else (package & component) set TransactionOption = Supported.

I have been testing transactions, basically I made time and transaction type dimension to fail and the package did roll back. I am stuck in the date dimension.Within Date dimension I got a stored procedure which populates calendar date attributes into Wrk_Date table. Then I have a data flow task which reads from thats working table, but it cant access it. I tried running SP_WHO2 command, and the status is SUSPENDED, being blocked by id -2.

I was going through step by step and identified the reason for locks. During step 2, if date table exist in stage database it TRUNCATES the table else it creates the table. Truncate statement seems to hold the lock and it is not releasing it further down the line. I have managed to get the rollback to work after removing truncate.

Therefore conclusion is you can't have Truncate and cant populate the same table in a single transaction in SSIS.
