Hi @snehalkausa ,

Below are the places you can check
Variable is attached to a variable set that isn’t linked to the catalog item.
Reference qualifier blocks the selected user.
Variable is not set to display on RITM/SCTASK.
A client script/UI policy clears the variable on submit.

You can do quick test:
Set the reference qualifier to javascript:true (no filter), submit again. If the value now appears on RITM, the issue is with your qualifier logic.
