PA Budget Workflow: Whose queue the notification is currently in?

We are in R12.1.3

We are using the web based Financial Plan Types in Project Management. Our Financial Plan Types are approved using Workflow.

Our PA Budget Workflow is customized and we are calling this workflow in the PA Budget Extension. The Budget is approved by the Project Key Members.

We would like to known when -

User submits the Budget, if there is a way to find in whose queue the Notification is in?

We can find the Notification Queue for Project Approval. But we cannot do the same for Web based Budget Approval

Thanks

Regards

Pradeep
