Establish a connection to BW

[santosh_k3]

Hi All,

Currently we are using PI 7.0, have the interfaces that are connected to BW(older version).

Recently we have up upgraded BW(older version) to BW 7.3

So , In order to establish the connection to new BW version

1)  what configurations we need to maintain in PI as well as in BW.

2) As most of the scenarios we have used Proxies to communicate with BW(older version)

    what changes, issues we may face while we migrate all the interfaces

please list out the activities that we need to perform in order to establish connection with BW 7.3

and successfully migrate all the interfaces to new version.

Thanks

HI Sai,

First, update component of the new BW to PI SLD (via RZ70).

2nd, connect your new BW system to your existing PI (make sure that you have the RFC Destination Type G that points ESR or IR)

• Host:
• Port:
• Path: /rep

3rd, make sure you have configured you BW system on its integration engine configuration (sxmb_adm) and the role is Application system and Corresponding Integration Server is your PI system.

4th, once you have the view of your Proxy (sproxy) you can then regenerate all Message Interfaces (Service Interfaces) proxies that needs connection from your BW and PI.

And lastly, create an XI communication channel going to your new BW systems and reassign all comm channels on your receiver agreements.

Hope that helps,

Cheers,

Hi Sai,

The best approch to integrate BW system is ABAP proxy, older version you are using proxy communication you can use the same proxy communication in  new version too.

Make sure that the proxy configuration settings in PI and BW are altered according to new system details.

Transport your proxy stuff to new system.

Best Regards,

Hi Sai,

  Since the BW system is upgraded better you regenerate all proxies, the new SAP systems are using different classes and methods to connect to PI system. You get dump if you run your old programs as it is.

Regenerating the proxy is safer way to sysnch the connection.

You can still maintain proxy communication between PI 7.0 and BW 7.3.  There wont be any changes in PI 7.0 side. IMO, existing proxy interfaces will function without any impact. For the changes related to BW 7.3 upgrades you might have to post in the BW forum.
