Problem
You are receiving an error message when attempting to process a refund through the automated refund workflow in ServiceTitan. The error message reads: Job parameter is not set for 'Job Invoice' configuration.
Solution
The error message occurs when you import an invoice and the invoice does not contain a job and invoice ID.
Manually process the refund outside of ServiceTitan.
Add a negative payment to the adjustment invoice.
If necessary, add a negative task to the adjustment invoice to ensure the balance is zero.
