Problem to access BPC from excel

Hello everybody,

I'm new in SAP BPC, Please I have a problem to acces into it from excel because we have the ERP and BW installed in the same machine but not the same client ERP in client 300 and BW in client  100 , the default client is  the one of ERP, what should I change ?

for the URL server it's likehttp://[URL]/sap/bpc/web/. for the acces from the web the link that works is like thishttp://http://[URL]/sap/bpc/web?re=1&sap-client=100.

Thank you
