I have a table of "Travelers" that has a relationship to a child table of "Traveler Steps." What I'm trying to get is a field on each child step called "Prerequisite" where the user would select a "sibling" record to indicate that another step must be accomplished before work can start on the next step.
I made a dummy app and created a Traveler Steps<Traveler Steps relationship so that the dropdown field exists, but now I need to filter the selections so that only the steps which are related to the same parent record are available for selection. I have been clicking around and can't seem to find anything....
Let me know if that works and I will upgrade this to an "Answer".
