Priority group in LTS

Question

Hi gurus, Can someone explain the purpose of priority groups in logical table source?
is it a substitute for contexts in business Objects?

Answer 1

Hi,
OBIEE provides priority setting option on logical table sources which helps the BI server to choose the appropriate logical table sources at run time. Usually lowering priority number for a particular logical table source increases the chances to get queried. Typically ’0′ or ’1′ will be used to indicate ’0′ as current data and ’1′ indicates past data.
We can use this priority setting in following three ways
1.Standard usage of Priority
In this way we can simply prioritize the logical table sources by setting the priority number for each LTS.
2.Permanently Reversing the Priority of Logical Table Sources
In this way we can reverse the priority setting in RPD for only certain subject areas. Its like we can build subject areas like one for current data and other one for historical data based on the same logical table
3.Reversing the Priority based on the User Query
In this way we can reverse the priority setting in RPD by passing value like '0' (keeping the priority defined in RPD)or '1'(reversing the priority defined in RPD) through a request variable.
