Trigger on create N:N Relationship in CDS

Hi,

 

We are migrating workflows to flows and the data model is fixed. We have a requirement to trigger a flow when a relationship is established between two entities in a N:N relationship. Since CDS creates a third entity in between to do the mapping, the idea was to take the CDS (current environment) trigger and configure it on the create of the in between mapping entity as "xxx_xxx_entity1_xxx_entity2. We also tried to suffix it with "Set", but the trigger gets corrupted saying the entity is not present in the metadata cache.

 

However, whatever we try, the flow is not getting hit. No run history is present neither. Is this caused because it is an "invisible" entity? Is there a workaround to achieve this? Since it's a migration, there is no possibility to create the "third" entity ourselves.

Hi Alice,

 

Thank you for your reply.

I've added the screenshot. It's a really simple flow to just see if I get it to work. But the trigger doesn't seem to be hit.

Thanks!

Hi @Niels_ ,

 

Could you please choose the entity from the drop down list in the trigger?

Re: Trigger on create N:N Relationship in CDS

Hey @v-alzhan-msft ,

 

Unfortunately, I'm not able to do that, since it is an intersect entity, created behind the scenes on the N:N relationship. However, the trigger is registered since I do not get an error when saving the entity is not present. So it does exist! So this should trigger when creating an N:N relationship.

 

Kind Regards

 

Niels

Hi,

 

I am also trying to figure out the same thing.  I don't think it is possible though.

 

I can create the Flow in the same way as @Niels_. The Flow saves fine without errors and I can even refer to the intersection attributes that are outputs of the trigger action in the following actions in the Flow.  The Flow just doesn't trigger when the intersection record is created.

Did you ever come up with a solution or work around on this?
