APO/BW: Creating datasource in BW for APO

Question

Hi
1. In creating a datasource (in BW) to be used in APO by righting on the cube in question and selected the option “Generate export Data Source”. It created a datasource 8CubeName, which
could be found under the InfoSource tree in BW. At this point, will APO see 8CubeName?
2. Where in  BW do we specify that it should go to APO? What if there are other systems which can also use this same datasource and how do we specify which one?
3. I also understand that update rules can be created on APO side, if so, what becomes of the updated rule created on the BW end? In other words, if update rules are applied on the APO side, and also applied on the cube on BW side, what happens?
4. Ok, so if I understand it right, this process creates a structure for datasource in BW, which is seen on APO DP. But which process actually pushes data from BW to APO DP?
Thanks

Hi Amanda,
I believe most of your questions will be answered by understanding that inside APO/SCM itself there is BW system, that works just like the BW that you had worked and understand well, mostly the data staging from BW to and from APO are like interaction between 2 BW (datamart), now try RSA1 in your APO system
1. Yes, APO will see the datasource after you replicated in APO from BW as source system; in APO we create source system with RSA1 like in BW, transfer application component (RSA9), this datasource will be displayed under 'Datamart'.
2. It just like BW act source system for other BW system, we have no need to specify in BW which one to go, but in APO we will use this datasource to assign to infosource in APO
3. Again in APO it just like a 'mini' BW there, so update rules in APO are indepedent used for APO-BW, nothing will happen to existing BW
4. Create infosource in APO and assign datasource from BW, create infopackage.
You can use process chain as well, yet in APO we have more process type (specific for APO usage like generate CVC, adjust time series, etc)
