How to find and use a specific kind of configuration/typology of "Event Types" in OTBI ?

Summary:

There is a specific kind of configuration/typology of "Event Types".

It is included in the "Manage Project Billing Value Sets" configuration form

You can get there as follows:

Setup and Maintenance >> Project Financial Management >> Manage Project Billing Value Sets >>

  searching for the value set by providing the name of the value set (for example "Event Type Invoiced Revenue") >>

  press “Manage Values” button to see a list of Event Types belonging to a specific set (see screenshots attached)

The problem is:

Is there any Subject Area to determine whether a specific Event Type (for specific revenue) belongs to the "Event Type Invoiced Revenue" set/category or whether it does not belong to this set ?
