I need to retrieve 1 object from the database, but it should exclude items in a list that I have. The only way I can imagine to do this, is by using an IN-like operator in my microflow. Is this possible? [BTW, I can't use a list to loop and exclude, as selecting the 1 object uses a complex micro-flow with multiple retrieval nodes. I need to exclude my selection's result set from a list]
Just retrieve all items, and then use 'list operation' -> 'substract' in your microflow.
