Issue with Dynamic Reference Fields in Catalog Item

Dear ServiceNow Community,

I am facing an issue with visualizing the following hierarchy in a Catalog Item, where all fields are reference fields:

  • User selects Location
  • Then Building
  • Then Floor
  • Finally Room

The hierarchy is structured as follows:

  • Room depends on Floor
  • Floor depends on Building
  • Building depends on Location

I created variables for Location and Building, but I realized that I can't make the fields dynamically dependent from bottom to top, so that the contents of the fields always adjust to the parent field. I noticed that there is a Tree Picker which can solve this in one field, but I couldn't integrate it into my variable in the frontend.

Our cmn_location structure is as follows:

  • Continent -> Country -> City (Location) -> Building -> Floor -> Room

Can someone help me with this?

On the reference variables, you should be able to set the ref_qual_elements variable attribute to set that dependency (e.g., ref_qual_elements=building would be added to the Floor variable, since it depends on the selected building value).
