What you'll learn

How to navigate to a specific portal row from a script
How to create a new related record via a portal
How to delete a portal row without affecting the parent record

Portals display related records and can be edited directly by users. Scripting the same operations — creating a new portal row, modifying fields in a specific row, deleting rows — requires understanding how FileMaker tracks the "current portal row" and when portal changes are committed.
