I am new to BOBJ reporting and I am trying to generate a data dictioanry for BOBJ reports , like what universe does a report look into, what object does a report column refer and what tabel in the DB does this report column inturn refer.. such kind of information.
Is there any system tables present in BOBJ like all_tab_cols,all_tables etc in Oracle or rep_all_mappings, rep_mapping_conn_ports in informatica?
You will not be able to do this through querying the BO repository database. The reason is that the database contents are encrypted. The only way I know of going about something similar would be to use the various SDKs to first "query" the InfoStore for the relationships between the report objects, Universe objects and connection objects.
As for where various Universe objects map to database entries, that requires SDK work to walk through the actual Universe to create the required results.
