Expression to check the value from a previous to a new value
Content (please ensure you mask any confidential information):
I have a property called Property A with possible values: 'Yes', 'No', and 'Blank'
A policy should be triggered based on changes to Property A according to the following rules:
- Trigger the policy when:
- 'Blank' to 'Yes'
- 'Yes' to 'No'
- 'No' to 'Yes'
- Do NOT trigger the policy when:
- 'Blank' to 'No'
For Yes if you see it always trigger, so that was easy to achieve and whenever it is 'Yes' trigger the policy
For Point 2, I am not sure how to achieve as it has to know the prior value and trigger only when it was 'Yes' and now became 'No'.
