Is launching a BPM when a relation has changed possible? Advanced pack

[abisbe]

Hi all,

I am trying to launch a flowchart process when a relationship has changed, but it doesn't seem to work. I have an entity Application, and an entity Selection, Application is related many to many with Selection with the relation selections, what I need is that when I add a course to this relation, or unlink one to be able to launch this flowchart process.
To achieve this I have tried to add as a start conditional something like Selections changed, in hopes that when that relation array changes, it'll launch the process, but this doesn't seem to work.

Any suggestions on how to address this?
I am not on the latest updates, I'm using 7.3.4 and Advanced pack 2.15.5 I know there might be some fixes already to this, but I'm in the middle of some campaigns and can't risk upgrading now.

Thank you!

PS: This post might be better in the Extensions area, but I couldn't decide which place was best, please move it if you think that it's better at the other place.

Hi abisbe,

In your case, it is better to use Signal Start Event with @relate.selections and/or @unrelate.selections signals: https://docs.espocrm.com/administrat...als/#default_1

Hey,

Not sure about the version you have but i think you can still use Signal event instead of conditional event even better you can use two signal events on the flowchart one for @relate.selections and another @unrelate.selections

so when a new selection is related to the application you can execute certain task and second signal when a selection is unrelated from the application you can execute a different task / logic etc.

Check this in the documentation

https://docs.espocrm.com/administration/bpm-signals/#object-signals

This is what you need to make it work.

Of course! How did I miss that! I'll make it happen and post the result, thank you both!

rabii I am a little confused because the signals you are talking about are found in the intermediate signal event, which as I understand it will not start a workflow right? and the on the start signal I cannot add @relate...

Hey,

Object signals

• Broadcasted along with the entity (record).
• Prefixed with @ character.
• Can be used only to initiate a new process or workflow rule.
• Can't be caught within a running process.
• Can be broadcasted by a running process.

As you can see in documentation they can be used to initiate a new process, i understand you can't find them there but you can just type them @relate.selections and that should work fine.
