Hi,
I have to read a file depend on one parameter in flow. my approch is like.

tFileDelimitor1-------->tMap1--------->tMap2-------------->tRunjob
| |
| |
| |
tSetGlobalVar tFileDelimitor2

from tMap one i will get one value to set Global Var and i will use this global var in tFileDelimitor2 . but i am unable to access the varibale which is comming from tMap1.

How to do this ??

Hello
You can use tFlowToIterate component, abou its usage, please see this [Forum, topic 5827] [resolved] How to use Flowtoiterate.
So, you job looks like:

tFileDelimitor1-------->tMap1-----tFlowToIterate---->tMap2-------------->tRunjob
|
|
|
tFileDelimitor2

Best regards
