Hi,

as I can see - you are already a 7-star user, so you are not the first day here (if Talend does not start to present them for Thanksgiving day !)

So, you must understand - if you want a help or answer, you are must provide some information - better screenshots and what you do, and what error, where exactly you required a help!

Sorry, nothing personal, but when you declare:

Tmap understanding issue????

please tell us - what is your issue?!!!

Hi Ankit,

    Below youtube video is having a simple example about match models.

    There are lot of videos and documentation as specified by @manodwhb. This will give you a good idea about tMap.

    The part 4 of the Talend best practices written by Dale is having good example about tMap usage.

https://www.talend.com/blog/2017/01/05/talend-job-design-patterns-best-practices-part-4/

    I would suggest to go through other three parts also to enrich your Talend knowledge 🙂
