Data is not refreshed when passing from parent interface to child.

I wrote a blogpost about data flow in interfaces a while ago. That might help you.

In general, I suggest to invest some research time in a much more simplified version of what you want to do. Once working and fully understood, go back to solving your issue.

You don't. I just wanted to make sure that the issue is not coming from one of the nested expressions.

Expression uses ri! value which is coming from Grid 1. Can you please help where do I need to specify a!refreshVariable? Grid 1 code is attached in below response

Hey, can you share the code snip for the grid 1 ?

Does your expression "DCC_castSubmissionSubstanceData" use local variables? If yes, you need to use a!refreshVariable with refreshAlways set to true.

That's a tricky behaviour of nested expressions calls.
