I am currently using Odoo 18 SaaS.

We have a loyalty program that is only for specific clients, but the general public should not be included in the program.

How can I exclude those clients?

I have tried using automation rules, but the rule is not working.

Any suggestions? Thanks!

Automation Rule: Prevent Loyalty Points
 
Trigger:
     Runs "On Save" (When the record is saved).

Conditions:
   Before updating:   The rule applies if all records match (currently 1 record). 
   
   Apply to:  Only if the Loyalty Card is in a specific list, in this case, the Public General card      (0448-bbb9-40b7).

 Action: 
   update: points 
   New value: 0  Force the balance to always be zero
