Hi, I am trying to work on below rules, there are no compilation errors and all rules getting executed. Obersation: 1. Able print message in first rule consequence. 2. Unable to print message in second rule consequence. 3. Not getting exception in the last rule. The Test Data i am working on should generate one exception in the last rule. It would be really very helpful if anyone can help.
