Business rule condition - Variable value changes

[Rocky5]

Hey Folks,

I am trying to execute a after update type business rule to copy "variable" value to "comments" field.

But the condition should be like, "when variable value changes" copy the value to additional comments.

In a business rule filter conditions "changes" operator is not available. 

How can I achieve this?

Thanks,

Rocky.

can you try condition in script like

current.variables.XXXXX.changes()

Hi Mike - I know this is an old post and I'm hoping you're still around to assist. I used this solution (yay!) to successfully trigger an event based on the business rule that matches a condition like this. However, I'm finding that if I change the value of the variable from a Flow, the business rule does not run. It only seems to run if manually changed by a user. Do you know if there is a limitation with how the variable is changed that would prevent the business rule from meeting the condition?

you need to use business rule condition like below

current.variables.test == ""
