I created a package which has the Transaction property Required. There are a number of 14 data flows tasks running 4 data flows in parallel one after the other. I get the errors posted in the Title and Descriptive Tag . Both the source and target database are SQL server 2005 databases and are on the same machine (localhost) . I am running it in BIDS. I updated the SQL Server to SP3
In Component Services I have the DTC configured to allow inbound and outbound connections and also Enable TIP and even select No Authentication required. I added the msdtc.exe in the Firewall
When I set up the Transaction property to Supported for the package it runs correctly.
Rearranged the data flow tasks one after the other in one sequence (not data flows tasks running in 4 sequences as before) and it did not fail.
Can I run multiple data flows in parallel in a package with Transaction property Required?
