I have an SSIS package with 5 separate data flow tasks. They are not linked and run in parallel. I;m trying to figure out how to stop the other data flow tasks when one task fails. Anyone got any idea?
I tried setting Max Fails etc but doesn't seem to stop the other tasks.

Try to add a follow-up task (could be a script task or a ole command task that issues a SQL RAISERROR stmt). Connect your 5 parallel tasks to this new task but only upon failure.

Hmmm that doesn't seem to work. The other Data Flow tasks seem to continue to run in parallel.

I tried something similar with a Script task which returned a dts error and that didn't work either.

If they run in paralllel, they are independent of each other.

However, this is not 100% true. Say you have 7 tasks which can run in parallel.

But only 4 of time can run at the same time (due to the number of processors available). If one crashes, the other 3 will continue to run. But no new data flow tasks will be started since the parent container (package, sequence container, for each loop, whatever) has already failed.

This makes sense

Thanks
