Calculation error on quote Q-00161: “UNAUTHORIZED”

The Problem

I guess that since you are reading this article you’re looking for the solution for the error in the title of the post: Calculation error on quote Q-00161: “UNAUTHORIZED”.

Error message on the Quote Details page

The Solution

There is this Knowledge Article from Salesforce: Salesforce CPQ Authorize New Calculation Service best practice that you should check in the first place. And yet, there is another one: Error ‘Invalid nil argument: OAuth Refresh Token’ in CPQ Quote Line Editor

For me, I did not have any “SteelBrick CPQ” in the Connected Apps OAuth Usage section.

Go to:

Setup -> Connected Apps -> Connected Apps OAuth Usage

And you will probably NOT see any CPQ in there, but you should!


In order to fix the problem, go to the

Salesforce CPQ Settings > Pricing and Calculation 

and reauthorize the new calculation service.
