Edit Data Source Page
You can edit an existing Data Source - the current data source selections will be shown.
The data source wizard will guide you through the process of editing the data source.
The data source name cannot be changed, but you can enter or change the description (optional).
You can select a different connection if desired.
Keep the selected translator or select something different.
Optionally, you can limit the tables for your Data Source by checking Filter Connection. Filtering is especially helpful for databases which have very large schema. If checked, an additional wizard step is shown - click 'Next' to proceed to the filter page.
Expand and click on the desired catalog or schema node in the display to see the schema tables.
The available tables for the selection will be shown in the tables list. You can enter a new table filter value if desired. The '%' wildcard can be used in your filter. For example, a filter value of 'A%' will yield all tables that start with 'A'. The table list will update when you change the filter text.
Once you are finished, click 
to update your data source. This will take you to the Data Source Summary page, which will show the updated data source along with your other sources.
Of course, you can hit the 
button if you no longer wish to edit the data source. Canceling takes you to the Data Source Summary page.
