Hi Shabaz,
On this one, what you are looking to do cannot be accomplished via a scoreboard query. It would require multiple joins, which would make for what we call "double-dotted-references" (crossing fields between more than one object), which is not supported for queries against the object layer, which includes scoreboard queries. For this you would need to use some type of reporting tool to pull the data you want to see.
Thanks,
Jon I.
