A default field set is a predefined list of columns and measures that are automatically added to a Power View report canvas when the table is selected in the report field list. Tabular model authors can create a default field set to eliminate redundant steps for report authors who use the model for their reports. For example, if you know that most report authors who work with customer contact information always want to see a contact name, a primary phone number, an email address, and a company name, you can pre-select those columns so that they are always added to the report canvas when the author clicks the Customer Contact table.
A default field set applies only to a tabular model used as a data model in Power View. Default field sets are not supported in Excel pivot reports.
Creating a Default Field Set
You can determine which fields, if any, are included by default whenever a specific table is selected in Power View. You can also determine the order in which fields appear in the list. To specify a default field set, you set report properties in the tabular model project.
To add a default field set
In SQL Server Data Tools (SSDT), click the table (tab) for which you are configuring a default field list.
In the Properties window, in the Default Field Set property, click Click to edit.
In the Default Field Set dialog, select one or more fields. You can choose any field in the table, including measures. Hold down the Shift key to select a range, or the Ctrl key to select individual fields.
Click Add to add them to the default field set.
Use the Up and Down buttons to specify an order to the field list. Fields will be added to the report in the order defined for the field set.
Repeat these steps for other tables in your workbook.
After you create a default field set, you can further influence the report design experience by specifying default labels, default images, default group behavior, or whether rows that contain the same value are grouped together in one row or listed individually.
