A rule in use at inspection bodies; names changed

Appliance power is recorded in one table and room ventilation in another. If the two don’t match, the ventilation calculation is in doubt.

Adding it up by hand on every report is slow and error-prone.

The rule

Checks: The appliances table with their power and the rooms’ ventilation table.
Blocks when: The appliances’ total power doesn’t match the rooms’. It doesn’t apply when the installation is a main line.
Message to the inspector: A message saying the power totals don’t match between the two tables.
Applies to: Forms with an appliances table and a ventilation table.

Test cases

This is how it’s simulated before saving: if a case doesn’t give the expected result, nothing is saved.

With the RETGAS connector in Claude, all you have to write is:

«The total power in the appliances table has to equal the ventilation table’s, except when the installation is a main line. Can you prepare it?»

It cross-checks tables

The engine doesn’t just look at one field: it compares totals from two different tables of the same form.
With its exceptions

Business exceptions, like the main line, are part of the rule.

The engine flags and the person decides. Rules only run when they’re active and linked to the form. How they’re configured

A calculation that doesn’t add up is a report that comes back. The engine does the sum for you on every visit.
