Data Missing from the Preview in the Data Source Tab

Issue

When viewing data from the Data Source tab of Tableau Desktop, not all expected values are shown in the data preview. 

Environment

Tableau Desktop

Resolution

The data preview in the Data Source tab is designed to provide a snapshot of what types of values are in each field. By default only 1000 rows are pulled into the preview. If the preview is sorted, only these 1000 rows are sorted.
To determine if data is missing from a data source connection in Tableau Desktop, create a view to display the expected data.
