Hi Robert,
Thanks for the clarification. It's important to keep the application as lean as possible. In your scenario, there is no need to include a tab strip or a cross tab in every single grid cell for that matter. 28 cross tabs would be quite heavy and there is no real need because you can simply include one Crosstab and dynamically change the content depending on the scorecard selection. I would suggest the following approach:
1. Since you only have 2 data sources, load them on startup. You could possibly load them in the background for better performance if needed;
2. The application could be structured in a master-detail pattern where you have the scorecard displayed in the master page and the cross tab in the detail page. This can be achieved as follows:
i. Add a Pagebook component to the canvas with 2 pages. Set the margins to zero and the width and height to auto;
ii. Add your scorecard to page one of the Pagebook;
iii. Add a cross tab to page two of the Pagebook. Also add a Back button in this page to allow navigation back to the Master page;
iv. When an exception icon is clicked on the scorecard, call a global script function to set the data source of the Crosstab to one of your 2 data sources. If needed, apply filtering to display only the relevant dimension members and measures. Then navigate to page two of the Pagebook via scripting to display the Crosstab.
With the above structure you have just a minimum number of components, while implementing an effective master-detail pattern to allow navigation from a summary display to the detail behind it.
Let me know if you have any further questions.
Regards,
Mustafa.
