DataSource Replication

Hi Experts,

I am kind of new to SAP BI, so I have some concerns when trying to load a Generic DataSource from SAP R/3 to SAP BI.

I am planning to extract a DataSource from SAP R/3 to SAP BI system. I run the RSA9 in SAP R/3 and thus I got all the application components and finally created the Generic DataSource from the SAP R/3 side.I checked it and everything works fine on R/3 side, but now the problem is on the BI side. I know that I should Replicate Metadata to see the Generic Datasource of SAP R/3 in SAP BI, but I have some concerns about it:

1. If I run the RSA9 in SAP BI too, will it have any effect (delete or update) in the current application components that are in the system or the new application components generated after running RSA9 will be changed only for me and not have any affect the other users on the system?

2. I also know that I should Replicata Metadata in order to generate the Generic Datasource from R/3 to SAP BI system.

My question is that if I replicate metadata for the Application Component in SAP BI, will it affect (delete or update) all the other childs of this application component that is already in use in the BI system by other users?

I don't want to change anything in other childs or application component, but only want to add this specific Generic Datasource from R/3 system to SAP BI. Could you please suggest me a way how should I do it or should I specify the Datasource name from R/3 at RSDS in SAP BW and that will work?

Thank you in advance for your time.

Best Regards,

Regys

    Hi,

    1. Why you want run RSA9 at bw side? Actually what you need?

    For generic data source you don't need RSA9 ecc or BW as well.

    Generic mean its custom data source which is created by us under related application component.

    2.Replication mean just it updates latest changes(app component and data source) from source to bw side . it won't delete any thing at bw side.

    if you have already have same application component then just you can replicate data source only.

    select your application component-->right click-->replicate data source or

    Tx - RSDS(bw side only, use menu option to replicate), enter your data source and replicate into bw.

    Thanks

    • Hi,

      No, You need don't need to do like that at BW RSA9.

      while replicating those also transferred. Other wise you can activate related applocation components from Bi content.

      Yes, you can select CO app.comp -->replicate it, replication will update the data sources which are related to CO only.

      if you do replication as above, it will replicate all data sources which are comes under CO, in that you better to select you info area as well.

      if do info area wise, it may replicate all data sources which comes under your info area.

      Or you just use Tx - RSDS At bw side, it will replicate your data source only.

      Replication may effect or may not. its depend on your data source update at bw side.

      other than your data source, all other data sources are sync with ECC/BW then no issue.

      if those are not in sync then while replication changes will update from ecc to bw in case of data sources.

      So best method is Tx - RSDS.

      Thanks

    Hi Regys,

    Yes your correct, better to use RSDS tcode to replicate specific DS.

    Hi Regys,

    As you said you have created genaric data source.

    With same existing fields you can create any
    number of data sources in SAP R/3

    It doesn’t effect any other application components

    Just replicate with RSDS and proceed with your
    next steps

    Thanks,

    I dont know about point 1 but for point 2 it depends, on 7.4 you can select the extractors within the application component to replicate, on lower versions it will automatically do them all. any which have been amended in R/3 and not replicated wont work in BW until they have been replicated.
