title: Auto update reports generated in report studio, when new rows are added in database
body: <p>I am using Cognos 10. I have created a model in FM using some tables in DB2. Then I have created a package and published it. I have also generated reports on this in report studio. Everything went well and the report looks fine. </p>
  
  <p>Now the actual problem is, I added some rows to the tables which I used for this project and the previous report is not updating. I tried refreshing data source in FM but it didn't update. So I had to create a new model and publish a package and generate a new report each time I add data to my DB2 tables. </p>
  
  <p>I have seen Tableau reports being auto-update when database changes occurs. Is this possible with Cognos? </p>
  
  <p>Is there any other way in which I can just do something in report studio and the report automatically updates to the new data present in DB2 tables?? So that I don't have to create a new model,package and report for each DB2 insert??</p>
