Trigger custom event when data changes

Need help
1

Hi there.

Context:
I need to run a number of workflows sequentially ensuring that the next one only starts after the previous has finished.
I’ve implemented a WFLoop thing that contains a start and end times - the end time is set empty when it starts and then filled with current time when finished.
From front, I use the Trigger custom event when data changes to listen to the field endTime changes in order to take action and start the next workflow.

Problem:
Trigger custom event when data changes is behaving erratically: sometimes goes through all events (may reach up to 11 workflows) and sometimes just stops in the middle although the endTime was set in DB.

Anyone has come across this problem?
Is Trigger custom event when data changes not reliable?

Thanks in advance for your help,

Just riffing here, but how many records are we talking about updating? There is a hard limit of 50,000. Perhaps you are hitting that?

If the workflow is only intermittently starting, it’ll be this.

If the workflow always starts but sometimes stops in the middle, that’ll be some other issue, for which you need to share more details of the workflow.

Hi @alan8
The heaviest workflow may handle 2000 records at most - this shouldn’t be a problem.

Hi @georgecollier
None of the workflows stops in the middle, it is the chain of workflows that is interrupted because front doesn’t detect that endTime for a workflow was updated and, therefore, it doesn’t call the next one in the chain.

Thanks for your help,

Another note I forgot to mention:
Everytime I start a workflow I also call the Trigger custom event when data changes for that specific workflow.

Like @georgecollier I’d like to seem some detail of the WFs to be able to help.

Hi @alan8
According to the post @georgecollier indicated, this problem occurs in live version, not in dev.
So, I’ll give it a try testing in dev version first to check if it is the same problem and I’ll let you know what the result is.
Thanks anyway,
