So I have workflows created on several different lists built using SP Designer 2013 on the 2013 workflow platform. They are set to run when an item is created, and 90% of the time, they do.

However, there's that 10% of the time where they simply do not start. Click the item and checking the workflow log, it shows the workflow never even ran.

Why would this be? I can't find a pattern or commonality between the instances.

It's hard to know what's happening here, I'd check the ULS logs when the items were added, maybe there's a clue there.

Were the items which didn't trigger the workflow created by an account acting as System? System accounts won't trigger workflows.

Hope this helps!

  • No they were not triggered by System Account, the initiator is always an actual user account. I've eliminated that as a possible cause first. Commented Nov 6, 2017 at 19:12
