How to edit Data transformation present inside the data view of TIBCO Spotfire Analyst 7.9

In Tibco Spotfire Analyst 7.9, a new feature has been added by which the added data transformation can be edited from the source view of the expanded Data panel. If the added data transformation cannot be edited, i.e. the wheel icon is not present in front of the added transformation, then it is due to the Data Table Source data being embedded. If you want to edit the added transformation then set the data table as a Link to source. You can check the data table properties from the Edit Menu >> Data Table Properties >> General tab.

Note that if the data panel is not visible inside TIBCO Spotfire Analyst, click on the Edit Menu >> Data, to enable it. Refer to the Section - "New Features" from the below link:
