Hi Hari,
Behind this flag there's no magic but work... An always better work provided by SAP DEV team.
About the planviz, better you upload a .plz file as we can navigate into it otherwise this thread will become monstruous rsss
Anyhow, this is not necessary for two facts.
Fist: Yes, put SQL engine to work works perfect if you only have on your paths colunar tables or other graph calculation views.
It's not exact say that always will not work for Analytical because it can work, but the optimization delivered with this artifact is use SQL engine that doesn't materializes the result. So if you stay on one engine. PERFECT
Depending on what you have on the graphical calculation you may execute these two analytics and materialize the result not only TWO times but many times.
In one of many tries we did here on our calculations the time increased from 25 seconds to 10 minutes. In this case we kept it on CE.
Second: You need to try it on SP7, as I said earlier things above the hood changed. There's no SQL generated anymore... Now it goest directly from CE to SQL optimized plan (no more generate SQL and parse it later).
The performance increased in two manners by this:
- there's no waste of time generating the SQL and parsing the temporary SQL statment
- some optimizations were lost on this to SQL -> to qo
Suggested action plan:
- move to SP7
- try again and post the complete planviz or open a ticket
Best regards, Fernando Da Rós
