Looking to define variable that is available to one test suite, not global variable

It can be done. See here:

Can we return a value from a callTestCase?

Scenario: I have a test case1 which will create a form. In this i have one field as form name and i am generating random name and saving. I have one more test case2 where i am calling the above test case1. But i want to access the form name which is entered in above test case1. Can someone please help?

You can create the {DOCUMENT_NAME} in TC1 and return the value, and then call TC1 from TC2 and use the {DOCUMENT_NAME} from TC1.
