If you had to explain the extraction process say from R3 to an IT Manager, how would you do this simply to include a level of technicality? Thanks
You can touch on few points like:
1>Possible Source sytems involved: Flat files, R/3, XML, Legacy applications, Applications like People soft etc.
2> Extractors: Standard extractors for R/3, Procedure of XML extraction, Tools like DBconnect for databases like SQL, Oracle, tools like Ascential datastage for applications like peoplesoft etc.
3>Steps involved in extraction, terminologies like datasource, Update modes, Record modes, Infosources, Transfer Rules, Update rules, PSA, Master data, Data targets like Cubes, ODS, difference between them.
4>Different scenarios with examples. Granularity of data, History of data to be covered, Application components within R/3 those are involved and the respective approaches for the same. for eg: LO for logistics, Co-pa, FI-SL, Generic extractions.
5> Features like Monitoring, Scheduling of data loads.
Hope this helps..
