RM rule was working error free before the update to the latest release 2.3.3.140
After the upgrade rule still is working but produces many errors.
I cannot spot anything wrong with this rule but obviously something is not right.
Question is - what is wrong with this rule?
Ops. Thank you for opening my eyes.
There is no "PR_Sum" variable at all and not even should be.
The correct variable is "Kitchen_PW_Sum" and it is Hub Variable
because it is used in multiple rules.
Rule is corrected and i am sure, error will go away:
Somehow this "PR_Sum" variable appeared during update plus DB conversion.
It did not exist in my original rule before the upgrade was applied.
But incorrect variable conversion is a very different story.
I will watch for another possible cases like this.
