Thank you George. The List of Item in multiple model report will list the extended object one by one. The result from the ListReport is listing all the values/attributes of the extended object into one table. So how to include the result of the ListReport into the one section of the multimodel report automatically?
What I doing now is generating the result from ListReport into a file, then include the file into the multimodel report, which is not automatic way. I think there is some other better ways to do it in the PD...
