Selecting fields on related tables using dot-walking Dot-walking provides access to fields on related tables from a form, list, or script. If the current table contains a reference to another table, any field on the referenced table can be accessed using dot-walking. Dot-walking references a field by building a chain of field names separated by dots (periods). For instance, incident.assigned_to.company references the company of the user assigned to an incident. The recommended limit for chain length is three levels.
