Hello
The tArray/tArrayIn/tSortIn are the virtual components. Please read this 2569 to learn more information.
After you define variables via tSetGlobalVar, you can use them like this in tJava/tJavaRow or other components:

globalMap.get("month")

Hello

How can i get First element in tArray????
globalMap.get("month") doesn't work, error:

tArray is a virtual component, you can't use it alone in a job and you can't get First element in tArray via the expression below:
globalMap.get("month")
Best regards
