### 3.14.8. Viewing and changing data sources for Test Cases

The Properties View shows the currently used data source for each Test Case. The following data sources are available:

Referenced Test Case
The data have come directly from the original specification of this Test Case. If the data in the referenced Test Case change, then the changes will also take effect here.

Local Test Case
The data being used were entered for this Test Case. Any changes made in the original specifiation of the Test Case will not affect the data here.

You can change from local to referenced test data using the combo box to reset the default value from the referenced Test Case.

Central test data set
The data have come from a central test data set (Section 3.14.9, “Using central data sets”).

Excel data file
An Excel file has been entered as the data source (Section 3.14.10, “Using an Excel file as an external data source”)

#### 3.14.8.1. Changing the data source for a Test Case

- The data source changes automatically to reflect the new data source when you enter an Excel file, a Central Test Data Set or when you enter new data in the Test Case.

- To change the data set back to the original specification data (referenced Test Case), first remove all Excel files or Central Test Data Sets, then change the data source in the combo box back to referenced Test Case.
