In order for the filters to be limited based on other filter selections when using in-database, external data tables, enable Cascading Filters for external (in-database) data tables as below:
- On the menu bar, select Data > Data Connection Properties.
- In the Data Connection Properties dialog, select the data connection of interest and click Settings....
- In the Data Connection Settings dialog, click the Performance Settings tab, and then select Enable cascading filters for in-database data tables from this connection.
- To save your changes and close the dialog, click OK.
Note: Enabling the cascading behavior for filters for in-database data tables results in an additional query load on the external data source. It is the user's responsibility to ensure that the external data source can handle the extra query load.
