Hi Daniel,
I just did several tests on my machine, using Double-Quotes ".
Everything works fine using them.
Do you have a copy of the policy that did not work previously?
Possibly there are other problems in it.
To come back to your original post:
The attributes "CIuserAttributeX" are only valid in the context of a CI. They cannot be set when processing an Alert.
Alerts have similar attributes, named "userAttributeX".
You can also reach out to me directly in case of further questions: Michael.Boehm@ca.com
