Ranking Analysis
About the narrative
Details covered in the analysis
The narrative includes:
an overview section that summarizes ranking changes in a measure (Profit) for the highest priority dimension (Country). For example:
subsections that describe top and bottom ranking changes and when they happened, for up to three dimension drilldowns. For example:
Note
The order of drilldown is determined by the order of dimensions set in Step 2 of the NLG Apps wizard: Data configuration.
The narrative wording depends on the selected aggregation types, referring, for example, to total, average, minimum or maximum values. For the Percentage, Rating and Ratio entity types, total values are omitted from the narrative as it does not make sense to sum up non-additive measures.
The app attempts to describe as much detail as possible, but when there is too much to describe the narrative will not report on dimensions below the second dimension drilldown.
Data requirements
All NLG apps have the same data requirements for field names and formats. See Data requirements for details.
In addition, each app has specific data requirements:
If your data selection and configuration do not meet the requirements, the wizard disables the app and displays a warning:

Dimensions and measures
This app can analyze:
one measure, up to two time dimensions*, up to three non-time dimensions.
Minimum requirement: one measure, one time dimension, and one non-time dimension.
Note
The Ranking Analysis app can analyze a maximum of one measure.
To replace the default measure with a measure of your choosing, you must first remove it using the Remove button. The Add measure button is displayed only when no measures remain.
*Time dimension requirements for each analysis period:
Analysis period | Required date fields |
|---|---|
Year |

Quarter |
|
Month |

Note
The Entity Type attribute for time dimensions must be set to DateTime in Step 2 of the wizard.

Not all combinations of aggregation and entity types are supported for measures. The Ranking Analysis app can analyze the following combinations:

Note
Entity types and other data attributes are set in Step 2 of the wizard.
Narrative options
You can configure these narrative options in Step 3 of the NLG apps wizard:

Period | Select a time period to analyze. The time dimensions in your data selection must include the period you select here — either as a Date field, or a Day, Month, Quarter, or Year field. Default: |  |
Ranking | Choose to report on only the top-ranking dimensions, the bottom-ranking dimensions, or both. Default: |  |
