DtsEventHandler. This container allows you to organize subsidiary tasks by grouping them together and allowing you to apply transactions or assign logging to the container. SSIS Data Flow Task hangs on excecution of Pre-excecute phase. For this reason, “package restartability” or checkpoints in SQL Server Integration Services was a huge relief. The Sequence Containers can help here also to group tasks together for execution and the previous precedence constraint will point to this parent Sequence Container. Hi, First of all, retainsameconnection is set to true :). At first I thought Sequence Containers were the way to go, but after doing more extensive research, it seems like the "sequence" benefit pretty much stops after their [deceptive] name.
