[rwnetwork]

Hi Community,

Can you please help explain the usage for all global variable options we have in Talend Data Integration ?  Please add/correct if I have missed any.

1.  tsetglobalvar

2.  tflowtoiterate

3.  tjava

4.  tcontextload

5.  Context tab in within a job

I would GREATLY appreciate detailed clarification.  

Thank you Community!

Hi, you have to go through below stuff to understand more I am giving for tserglobalvar and you can find for other components from the below site.

Thank you much for the references @manodwhb.  I do know where these are located, I guess I should have been more specific in my detail search.

I'm looking more for the community's help on:

• Business cases uses for each - if possible - like, "I've learned that this component works great when you have the need for a hardcoded value..."
• whether or not they can be used within an ENTIRE job or just within one specific subjob
• whether they can be used for more than one value or multiple values
• whether they can be used for lists

I don't see this kind of details in the Talend help area?
