About Dynamic Expand for Tree Categories

You can configure a tree category so a list of business objects is inserted under it automatically. For example, Folder categories are often configured to display all folders without users having to view the folders first.

This feature is recommended primarily for hierarchically organized categories such as Folders and Subfolders. For best performance and consistency of behavior across applications, the preferred method of navigation is to use the standard tree behavior that does not use the Expand Inquiry. If you require this setting, restrict its use to categories containing relatively few objects.

There are two ways to get the list of business objects to insert under the category:


  • JPO and method

    The system obtains the objects using a method in a JPO. You specify the JPO using the Expand Program setting, and you specify the method using the Expand Function setting for the command object. If you add both the JPO and inquiry settings for a category command object, the JPO takes precedence.

  • Inquiry administrative object

    The system obtains the objects from the database using an inquiry object. You configure this behavior using a setting called Expand Inquiry for the command object that represents the category. The value for the setting is the inquiry object name. For example:

    Expand Inquiry=TMCFolders
