I have two entities that have a many to many association. That association is created between two individual objects of these entities through a microflow that users enter using a button. However, if the association already exists between the two instances, I want to show a different message. Is there a way I can use an exclusive split to check if the association has already been created between the two objects?
Yes absolutely, you can check if an association is empty or not in an exclusive split: $Instance1/Instance1_Instance2 = empty.
