If Component (this) is selected, a new component instance variable will be created and used to determine the variable value. This way, you can use Environment Manager variables to set SOAtest environment variables—without going to the SOAtest UI. One variable will be created for each unique variable/value pair. For instance, if you have 6 test scenarios that use the WSDL SOAtest variable, and they are all set to the same WSDL value, one component instance variable will be created. If 2 of those test scenarios use one WSDL value and 4 others each use a different WSDL value, 5 component instance variables will be created: WSDL, WSDL_1, WSDL_2, WSDL_3, and WSDL_4.
For details on defining variables at the system, environment, component, or component instance level, see Working with Variables.
Confirming Variable Values
...
In the Variables wizard page, you are presented an aggregation of all variables associated with the component instance—including the ones that were added to represent SOAtest environment variables (as described above).
If you want to change a variable value, check Override, then specify the new value in the text field.
