Error in Message Mapping

Hi Experts,

I am facing one issue in mapping.

My mapping is working fine in production system however when i am testing the same mapping i in quality and development system its giving the error

I am getting the following errror while testing the scenario in message mapping test tab of quality and development system.

Cannot produce the target element. Check xml instance is valid for source xsd and target field mapping fulfills requirement of target xsd.

Please provide your valuable inputs on this.
