Populating cascading listboxes without processing the query in HIR 8.3

Question

I have 2 listboxes. First listbox populated using Group Number. Second Listbox should contain all account numbers corresponding to the Group Number selected in the first listbox, I need to do this without processing the query. I tried this way :
1.     Created a query section “Query” and in that created a limit Group Number. Through this limit I am populating the first lisbox.
2.     Created another query section “Query2”. In that created Group Number as first limit and Account Numbers as another listbox.
3.     After selecting the Group Number from listbox1, I am passing this value to the first limit of “Query2”.
4.     I am doing RefreshAvailableValues on the second limit of “Query2”. Now I am expecting the records corresponding the selected account number in the second limit of “Query2”. But I’m getting all the available values.
What is wrong in the above or any better solution is available please suggest.

Answer 1

Why do you want to do this without processing a query.
Each time you execute the script RefreshAvailableValues you are essentially executing a query...look at the Query log.
As for the issue in # 4 you will want to change the properties on the Data Model. From menu select
DataModel
- Data Model Options
check the Filter/Limit tab and try out different options
--- below is from 11.1.1.1 help
Data Model Options: Filters
Use the Filters tab to specify filter browse level preferences and to select global filter options.
When you use Show Values to set filters, you may sometimes need to sift through a lot of data to find the particular values you need. Filter preferences enable you to dictate the way existing filters reduce the values available through the Show Values command.
For example, you want to retrieve customer information only from selected cities in Ohio. However, the database table of customer addresses is very large. Because Interactive Reporting applies a default filter preference, once you place the initial filter on State, the Show Values set returned for City is automatically narrowed to those cities located in Ohio. This saves you from returning thousands of customers, states, and from all sales regions.
You can adjust this preference so that the initial filter selection has no effect on the potential values returned for the second filter (all cities are returned regardless of state).
Filter Options
Show Minimum Value Set—Displays only values that are applicable given all existing filters. This preference takes into account filters on all tables and related through all joins in the data model (which could be potentially a very large and long running query).
Show Values Within Topic—Displays values applicable given existing filters in the same topic. This preference does not take into account filters associated by joins in the data model.
Show All Values—Displays all values associated with an item, regardless of any established filters.
Tip:
When setting these preferences for metatopics, be sure to display the data model in Original view.
Global Filter Options (Designer only)
Show Values—Globally restricts use of the Show Values command in the Filter dialog box, which is used to retrieve values from the server.
Custom Values—Globally restricts use of the Custom Values command in the Filter dialog box, which is used to access a custom values list saved with the Interactive Reporting document file or in a flat file.
Custom SQL—Enables the user to code a filter directly using SQL.
Note:
The Topic Priority dialog box is displayed only if you first select join in the data model.
Note:
Since most data models do not have the same set of topics, you cannot save changes to the topic priority as default user preferences. (For more information on default user preferences, see Saving Data Model Options as User Preferences.)Often times if I am trying to load controls for parameter screen I will have a seperate query and results section for that purpose. Then I use the Filter/Limit on the Results section to control the cascade feature you are trying to accomplish. In your case your results would contain the distinct list of Group Number and Account Number.
