BI Financial DBDIFF Analysis Issue, Core formula: DB --> ETL --> DW vs REF file Cause of error: 1. DB/DW Connection Issue 2. SQL Issue 3. Product Bug 4, REF file not updated Physical requirement analysis: 1. Source DB: EBS, PSFT, Fusion... DB Instance 2. DW: Ignore the storage form of the data source and store the data in the same form. Logic requirement

is, dbupdated or REF file not updated.2. Derived data:If the value of a field in the DW is 45.2 and the ref file is displayed as 45.3, the value of this field is etlmapping by the addition of the value in two source db, i.e. (20.1+25.1), in the calculation, the value shown in DB is 45.2. This situation is represented by the core formula:45.2-to-ETL-to 45.2 vs 45.3. This indicates that ETL is not a problem, REF file not updated. type two: when the number of rows output by the out file is not
