Talend: Using globalMap.get() (or context.parameter) to dynamically populate Filename in tFileTouch component

Using globalMap.get() (or context.parameter) to populate Filename in tFileTouch component.

tFileTouch is used to touch a file (create an empty file) with a given namepath.
What we can do very easily is use global variables declared in the job to derive the filename dynamically for tFileTocuh component - as below
 (in place of globalMap.get we can also use context.parameter too)
