AGGREGATION	It displays the default aggregation for the selected feature.	The default aggregation method is Count. The available options for aggregation function are: Count Sum Min Max

Adding Enumeration for a Feature

You can add enumeration to your dataset. Enumeration is adding short values for the original values of a feature.
For example, consider a dataset containing the list of country names in the world. Using the Enumeration feature, you can add codes for the country names in your dataset - USA for the United States of America, UK for the United Kingdom, IND for India, and so on.
Enumeration is especially helpful for the datasets with text data and many columns

Notes:

You can add enumeration for multiple features in a single dataset.
The enumerated values should be unique. If you add multiple enumerated values for a single value, Rubiscape considers only the latest enumerated value.
The enumerated values are displayed when you explore the data dictionary or use it in a workbook or workflow. You can notice that the enumerated values replace the original values.

You can select the type of enumeration you want to perform. There are two types of enumeration -

Manual enumeration – Adding enumerated values manually
CSV enumeration – Adding Enumeration values using a CSV file

The types of enumeration are explained in detail in the following sections.

Adding Manual Enumeration

You can add enumeration manually by adding enumerated values to a feature.
To perform manual enumeration, follow the steps given below.

Select the dataset from the data dictionary canvas.
The features of the dataset are displayed in the PREVIEW pane. To view the PREVIEW pane, refer to Performing Dataset Operations.
Click the ellipsis () corresponding to the required feature.
A list of options is displayed.
Click Enumeration.

The Enumeration page is displayed.
Select the Manual Entry radio button on the Enumeration page.
The fields to create manual enumeration are displayed.
Enter the new enumerated values you want to create in the Please enter new value field corresponding to each original value.
Click Save.
The Enumeration page is closed.
Click the Save icon () on the top right corner of the Data Dictionary page.
The newly created enumerated value is saved in the dataset.

Notes:

To remove the enumerated values, click the Clear File at the bottom left corner of the Enumeration page, and click Save.
You can add new values and the respective enumeration for those values in Manual Enumeration.
To add new entries to the selected dataset column in manual enumeration, click Add New Entry in the top right corner of the Enumeration page.

CSV Enumeration

You can perform enumeration using a CSV file. To perform CSV enumeration, you need to create a CSV file with original and enumerated values and save it in your system.
To perform CSV enumeration, follow the steps given below.

Select the dataset from the data dictionary canvas.
