unconnected component_how to analysed Production Log massage?

Hi Bentley,

I'm facing with unconnected component problem. It only simple piping model with 3 pipes and 2 elbows, but it failed to generate isometric dwg.

Please refer photo attached. I view the production log, but i don't know how to analysed the error data stated in that log.

Please explain how to analyse that log data. Is there any reference note that i can refer if this error happen again for the other component such as flange, gasket, fastener & etc.
