BI 7.0 Connect multiple source systems to a single ECC client ?

0 Kudos

Hi experts,

We have a requirement at our client.

Our client has one development client for 2 different companies. They do have 2 QA environments and 2 Production environments, but they are joined in Development.

We want to connect this 2 companies to our BW system. We created one source system connected to the client but we can not create a second source system pointing the same client.

Our Basis team had tested it and they receive the message RSAR201 "Source system <xxx> already exists".

He said that even if you use a different RFC to connect from BW to ECC, you do not have the option to choose a different RFC for the return connection, and you do not have the option to say what source system name you want.

Any ideas to sort this out?

PS: We can NOT create a new client in the source system.

Thanks in advance,

Hi Leticia,

Please note source system might have multiple client but in BW there can be only one active connection with a client .

For eg : consider source system has 2 clients namely ECC100 ECC200

Now BW at any point of time can have only one active connection with either ECC100 or ECC200, not both can be active at same time

For this , I have a question - how do you distinguish developmwnt for company A and B in your ECC development system ?

Is it through different clients ..?

And how do you do transports from your ECC dev to specific QA / PRD systems..? in al likelihood - there might be multiple clients for each company in your development system and you should be able to have a single ECC dev source system in your BW and then use the MADT field to distinguish development - but then transport from BW DEV to QA / PRD would be a nightmare since it would require that you switch the source system conversions every time you do a transport...
