Multi key (or composite key) dimension for operational reporting
Hi, I am creating operational reports in OBIEE 11g with PeopleSoft FSCM as source. As they are straight forward reports, I am planning to use OLTP tables directly for my OBIEE reporting.
Here is the simplified scenario - ACCOUNT_TBL_VW is dimension table which has BUSINESS_UNIT & ACCOUNT_ID as keys.
I have LEDGER Fact that has BUSINESS_UNIT, ACCOUNT_ID & other dimension keys with amount measures.
How do I link my LEDGER Fact with ACCOUNT Dimension?
Can I join multiple keys of Dimension with multiple keys of Fact? like this
ACCDIM.BUSINESS_UNIT ---> LEDGFACT.BUSINESS_UNIT
ACCDIM.ACCOUNT_ID ---> LEDGFACT.ACCOUNT_ID
As it is operational reporting, I don't have any ETL type process to prepare single column primary key(surrogate key) in Dimension Table & modifying Fact Table with dimension surrogate key value.
