This Full Query on One analysis. Its Normal? Thanks DJe

Without knowing your rpd modelling I cannot comment on whether it is correct, but yes, the logical model is typically massively simpler than the physical model, I would not see what you are seeing as a bug, merely as an indication of the underlying complexity of the physical model.

its like flat table join with time dimension.

I think I need more than your sentence there, but reading between the lines you are saying 'Why is the OBIEE sql so complex when you would think it would just be select ..... from fact f, time_dimension td where fk.tkey = td.key' - then yes, partly I agree with you (all of that select from select from ... stuff seems wholly pointless), partly OBIEE does add value and optimises, and dependent on the exact nature of the query and view used some of the 'work' may also be done on the client.
This is somewhat dated (depending on what version you are on) but you might find this interesting; -

Nice reference and nice write-up, Robert!
@Dje07 OBI lives and dies with its models. So basically if they are done sub-optimally or just...wrong...then it can never produce any meaningful or optimized queries.
Already if I see something called "SA."Report AA" personally I have serious doubts as to the modelling in the RPD!

lol re "SA."Report AA"

And thanks for the compliment - feels better than all of the 'badges' you get on the forum!
