Smart fields: calculation, rollup, lookup, serial number, catalog

Smart fields fill themselves in: they calculate a formula, add up the numbers of linked records, show data from another record, number invoices, or build the lines of a quote. No one types them by hand.

A formula on the record’s own fields
{quantity} * {unit_price}
As soon as you save

The total value of a client’s contracts
In the background, after a few seconds
Shows a field from the linked record without copying it
The city of a contact’s company
Every time it’s shown
A unique number that goes up
INV-2026-0045
Only when the record is created
Picks records from another unit, with line items and tax
A quote built from products
When you pick

Relation → lookup → rollup

A relation links one record to another. A lookup shows one field from the linked record. A rollup adds up the numbers of all the linked records. Lookups and rollups need a relation first.

Chaining fields

A calculation can read a rollup, and a rollup can add up calculations or other rollups, up to 3 levels of rollups. Example: the payment → the total paid on the invoice → the client’s balance.

A real example

Shield Security Co.
The situation

Quotes are worked out by hand in Excel, and mistakes creep into the tax.

What they did
  1. A “Products” unit with a price field.
  2. In “Quotes”, a smart catalog in line items mode, and a yearly serial number QT-2026-0001.
  3. A calculation field: IF(SUM_LINES({items}) > 50000, "Needs approval", "Direct").
  4. They printed the quote with a document template.
The result

A quote is built in two minutes, with a unique number and the right tax.

A made-up company, to show the idea. The numbers are rounded.
