An Auto Fill field looks up a matching record in another table and copies values from it into this record. Use it to:

  • Fill in a price from a Products table when a product code is entered
  • Copy a customer’s email or address onto an order or invoice
  • Suggest values to users instead of filling them in automatically
  • Keep a snapshot of a value at the time the record was created

Create an Auto Fill field

  1. Click + Column → Auto Fill.
  2. Enter the Property name (for example Customer Email).
  3. Configure Auto Fill settings:
SettingDescription
Source TableThe table to look up, for example Customers or Users
Filters → + Add filterHow to find the matching record: pick a column in the source table, an operator (for example Equals), and a value. The value can be fixed, a field of the current record ((x)), or a formula (ƒx). Click + Add condition to add more rules.

Tips

  • The (x) value picker only shows fields whose type matches the column you’re filtering on. Match text to text, number to number, and so on.
  • Choose Trigger Columns carefully. If you don’t pick the field the filter depends on, the value won’t update when that field changes.
