Extraction From Oracle 10g DataBase into BW 7.3...
I'm working on SAP NetWeaver BW 7.3 and I have a requirement to fetch data of couple of tables from "External System" Database. My BW 7.3 database is Oracle 10g and Database from which I will extract data is also Oracle 10g. I have not extracted from "External System" like from other Databases.
1. What activities I need to perform in BW 7.3 system?
2. What help I require from my BASIS personnel?
3. What is the step by step procedure from creation of Source System, DataSource, Data Target and Data Flow?
4. How to proceed with extraction from Oracle 10g Database into BW 7.3?
5. If I need to extract couple of tables do I need to have a separate "DataSource" for every single table?
I will appreciate your reply in this regards.
