After you have modified an XML design file, you can upload it through the Add New Data Source page. Alternatively, you can create a new Data Source based on a modified file or even on a design file created from scratch.
Log in to the server as an Administrator.
Locate the Data Source:
Choose View > Search Results.
In the Filters panel, under Types, click More choices.
Click Data Sources.
To update an existing Data Source, right-click the Data Source and select Edit from the context-menu.
To create a new Data Source, select Create > Data Source from the main menu. The Data Source appears in the Data and Design page of the Edit Data Source or Add New Data Source dialog. If you are creating a new Data Source, you must select a data source before you can proceed.
Select Upload under Data Source Design, then click the Choose File button. A local File Upload opens.
In the File Upload window, locate the XML design file, then click the Open button. The server validates the uploaded XML file. If there are syntax or semantic errors, the current design is not replaced. You can make changes to the XML file and upload it again until there are no errors.
If you used only supported features in the design file, verify the uploaded Data Source design by selecting Edit in Data Source Designer from the Add/ Edit Data Source page. Make sure the settings you made in the XML design file appear as expected on the various tabs of the Data Source Designer. If there are any errors or inconsistencies, you should make changes to the XML file, upload it again, and verify it again.
After the design appears correctly in the Data Source Designer, you may make further modifications on any of the tabs.
In the Data Source Designer, click the OK button.
Click the Submit button to update the Data Source in the Repository.
If you modified an existing Data Source, you must clear the Ad Hoc cache of all queries based on the Data Source. This removes any data that was based on the old instance of the Data Source and avoid inconsistencies in new reports.
