Hi Sumit,
You were actually on the right track with altering the steps in the process model that generate the report. However, the sequence where the report is actually saved (with the correct format) is in the Test UUT sequence of the process model. All you have to do is add a statement step after Write UUT report that sets the format to txt, clears the report and sets the file path using the expressions:
Locals.ReportOptions.Format="txt", Locals.Report="", Locals.ReportFilePath=Locals.ReportFilePath+".txt"
You can then repeat the previous five steps to create the report. I am including the example process model so you can see how this can be done. Change your Station Options to use this model instead of the default model and run as Test UUT.
