What are the limitations for parameterizing test objects in shared object repository?

When parameterizing using a Data Table parameter:

1. You must use the global data sheet. The Current action sheet (local) option in the Data Table Parameter Options dialog box is disabled.
2. Your change to the object is saved in the shared object repository, but the corresponding Data Table is saved only with the test in which you are currently working.
3. The column name in the global Data Table related to the parameterized object must be the same for every test using the same shared object repository.

The data within the global Data Table column can be different for each test .
