Add field to tree picker hierarchy

[thomasawhit]

On the User table, the Location field has a tree picker. I have two questions about this.

1. The hierarchy for this is Country -> State -> City. Where is this defined in ServiceNow? How does the tree know that this is the structure? I don't see any dependencies for these fields.

2. How do I add a field to this tree picker? Specifically, I want to add ZIP / Postal Code to the tree picker after City, making the hierarchy Country -> State -> City -> ZIP.

How can I accomplish this?

Hi @thomasawhit 

"A hierarchical table is any table that has a parent field pointing back at itself.", for Example: If you see Parent field of locations. Location record Parent is mapped with City. City itself is another location record with Parent mapped as State and etc.

if you want to include zip code in the hierarchy, you need to create location records with name as Zip codes and parent of zip codes should be mapped to City location record. hope it helps.

@thomasawhit 

that's coming from platform.

I don't think you can add your own logic there.
