On your editing page (I assume you already have that) create a custom save button that calls the microflow. In the microflow you can create the object for the other entity, set its attributes, set the association between both and then commit both of the objects (and close the edit page if you want).
Let me know if there is any of this you're not sure how to do.
Johan,
THANK YOU! When I was creating the microflow as you suggested it first added a duplicate entry to the Recipe table, but then I realized that I had to change the Set reference Entity to Catalog. Then everything worked perfectly.
I have to say that Mendix is VERY COOL! It is a much simpler way of building an application them before.
Hi – how/where can this microflow be triggered to add records to associated entities, if the new records are coming from a file import? So once the file imports, I am trying to have any new records populated into the associated entity.
