Button that add relation, but remove existing ones

Hi, I am adding relations through a list in order to categorize what data another list displays. However, I want the the lists that set relations (add relations) to also remove any existing relations, or else the entire categorization system fails. How can this be done?

Thanks!

Hi @civec ,

If your relationship property is 1-to-m, it will automatically be replaced.

If it is many-to-many, you need update action and remove and add collection name.
