Process Result

Contents[Hide]

The Process Result transform represents the final output or result of the data cube (ETL process).

This transform doesn't do any data processing but it allows you to configure the measures and hierarchies that will be made available to downstream items such as metric sets.

1. Data cube elements

Click the Process Result transform to see the Data Cube Elements panel, which shows the list of output measures and hierarchies for this data cube (ETL process). Measures and hierarchies are color-coded the same way as in metric sets.

1.1. Hide elements

You can hide a measure or hierarchy from the output by clicking its grey minus icon on the very right. The measure or hierarchy will be listed under a Hidden section and you can easily unhide it by clicking its plus icon.

A hidden measure or hierarchy is hidden from the data cube output but will still be available for subsequent linking in hierarchy keys (e.g., if you need to use the data cube later to define a hierarchy).

1.2. Edit elements

You can access additional options related to a specific measure or hierarchy by clicking its green or orange tile to edit it. 

The Output Element dialog will open, where you can change the Caption, set a Description, and customize various settings including supported aggregators or a measure's number formatting.

For elements that could be either a measure or a hierarchy, you can switch between them by clicking Switch to a hierarchy or Switch to a measure. Non-numeric type data can also be switched to a measure in order to perform a count or distinct count of that element's values, similar to adding a hierarchy count measure in a metric set.

1.2.1. Replace with a hierarchy

Simple columns of text, dates/times, or numeric IDs each automatically become an 'implicit' or generated hierarchy when output by the cube and used in a metric set. You can replace such columns with a hierarchy you've created and set up with features such as multiple levels and custom sorting, or with a time dimension hierarchy for date/time data. For example, you could replace a ProductID column with an existing multi-level Product hierarchy.

To do this, click Select a hierarchy or level to use as a replacement in the Output Element dialog.

In the Open dialog that appears, select your hierarchy from the Hierarchies folder, or for time dimensions, click to expand one from the Time Dimensions folder and select one of its hierarchies.

Selecting the hierarchy will link the column to the lowest level of the hierarchy by default, or you can expand the hierarchy and select a specific hierarchy level instead. For text or numeric columns, you must choose the level with keys that were set up to match your column's values.

Click the submit button at the bottom when finished.

Returning to the Output Element dialog, you can optionally click to Set up additional links between the hierarchy and the cube's data at other levels if your data also matches with their keys, which can improve performance. You should also set up additional links if you chose a hierarchy level that has multiple keys so that each key is linked to your cube's data.

In the dialog that appears, select a Hierarchy Level from the dropdown. To add a link, drag an item under Hierarchy Keys and drop it onto the corresponding item under Result Elements.

1.2.2. All member caption

The "All" Member Caption can be set to customize the text identifying the top node of the hierarchy. If this value is not set, it will display the value located in the localization file for the current language.

Note
Implicit date hierarchies used with a Calendar filter will use the caption from default time dimension.

1.2.3. Attribute hierarchies

If the element is an implicit hierarchy, you can define other elements that should appear as attributes for this hierarchy, the same way as attributes defined in a hierarchy created from the main menu.

You can select one or more elements under Attribute Hierarchies: to select multiple, click and drag, or hold the Ctrl or Shift keys while selecting.

After submitting the dialog, the hierarchy with attributes defined will appear with a special icon, and the elements selected as attribute hierarchies will no longer be listed as separate hierarchies in the Data Cube Elements popup.

1.2.4. Security options

Security options

The Anonymize Members option is available for implicit hierarchies (except for DateTime columns), and when enabled will generate a new value to replace each unique original value in the column so that it does not directly identify the original. The generated values may change over time.

The Security Hierarchy option allows you to accomplish row-level security by filtering the data by that hierarchy's values where they must match the custom attribute value for each logged-in user. For details, see Using a security hierarchy to filter data by user.

1.2.5. Supported aggregators

Both numeric data and non-numeric data elements have a Supported Aggregators setting, which determines which aggregators are available when this data is added under Measures in a metric set. To select multiple with a mouse, click and drag across the options, or click while holding the Ctrl or Shift keys on your keyboard. The number of available aggregators is a consideration for the amount of memory consumed when using in-memory storage.

You can drag a hierarchy or non-numeric to Measures in the Data Analysis Panel to perform a count or distinct count of its values, so the Supported Aggregators setting determines how many of these two are available.

1.2.6. Formatting measures

The formatting options available on a metric set can also be defined ahead of time for a measure in a data cube, which will be the initial settings used whenever that measure is added to a metric set.

Click Define text formatting to open the Configure Formats dialog, which contains a variety of options for formatting numbers as text. For details on these, see the article Formatting text.

2. Configure

Double-click the Process Result transform to see its configuration dialog, or select Configure from the toolbar or context menu.

Uncheck any columns which you don't need to be part of the data cube output. This will completely remove the column from the data cube and will make the column unavailable for subsequent linking in hierarchy keys (e.g., if you need to use the data cube to build a hierarchy).
