2- Create your subreport template.Creating a subreport is not a rocket science, its just a simple report as we have created in step number 1.
3- Add parameter to the subreport.
To connect our subreport to the main report we need to create parameter in our subreport. The purpose of creating parameter in subreport is that subreport report query will receive the guide from the main report via this parameter which we are going to create in this step. And we will link our main report to subreport via this parameter.
To create parameter go to Report Inspector tab and right click on Parameter tree and choose Add parameter.
Now go to properties of your created parameter and set name and type (parameter class) of parameter.
4- Now define query for your subreport.
Now that we have created our main report, subreport and parameter for subreport, Its time to create report query for subreport which we have created in step number 2. To fetch data from that query we use parameter in where clause to limit items in our subreport. To create query for that subreport open report query window add your query and in where clause use parameter which we have created in step number 3. In this process we are going to tell subreport that fetch only those data that are linked to our main report. Now click on OK button.
5- Add subreport to you main report
Now that our main report and subreport have been ready. Now its time to link both of the reports. Go to your main report and drag Subreport in your desired detail band of your main report. If you are unable to view Palette window than press Ctrl+Shif+8. After draging subreport you will see subreport wizard from that wizard select “use an existing report” and browse your subreport which we have created in step number 2 and click on Next button.
Now select “Use the same connection used to fill the master report” and click on Next button.
Now select “Store the directory name in a parameter” and click on Finish button.
Now you have successfully add subreport in your main report, adjust its width and height according to your need.
You are now ready to run your main report. Running (i.e. previewing) the main report will automatically run the subreport(s) as well, and the data from the main as well as from the subreport(s) will be included in the report.
