Hi, I have a dynamic child package that gets called concurrently by a parent.
I have deliberately set the FailParentOnFailure to true on the execute package step of each load yet when one child fails, the parent still carries on with the other child.
I have done some reading around this but can't find a concrete solution that takes into account concurrent child packages.
Does anyone have any ideas please?
Cheers,
Dave

You have two (or more) child packages running in parallel.
Your requirement is that if one of the child packages fails, processing stops immediately ... is that correct?
If so, I don't think it can be done. Once a package is executing, it pretty much looks after itself and does not respond to external software interrupts. The parent package will fail, eventually, once all of the parallel child packages have finished executing.
You can code round this, to a point, by writing and polling some sort of shared log table within your packages ... but this still won't force an interrupt.
I'm not 100% certain of the above, but that is my experience. If others know better, please post.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

Hi Phil, thanks for replying. This is exactly what I thought. This is all at a POC level so far.
I originally had my dimensional loads running in sequence but the business now requires parallel loads. Obviously, if I had 10 dimensions loading in parallel, if one failed I didn't want to wait for the other 9 to finish before logging a failure but it seems to be a moot point unless I put a check in between each step of each dimensional load to test for a failure but that seems a little overkill.
Cheers,
Dave

One possible solution ... which I don't particularly like ... would be to load the dims in parallel in a single package.

Yep, I don't like that either!
Cheers,
