I need one quick help.
Can someone confirm in which version was TPT launched ? Is it TD12.x or TD13.x ?
Also where can I find similar details for other utilities ?
No, it is earlier than 12.x.
And strictly speaking TPT is part of TTU (Teradata Tools and utilities) not part of the DBMS, so you're really asking about "what version of TTU?".
Also bear in mind that TPT went through various name changes ("Teradata Warehouse Builder" - TWB - comes to mind).
You might try the Teradata manuals website (info.teradata.com) and see if that has (very) old manuals.
