Analysis for Office requirements

Hi,

I am using Analysis for Office (AFO) versión 2.2. It worked fine in my previous client, but it doen't work fine in my actual client. When I try to open a workbook via SAP Netweaver Platform I get an error message (warning) telling that the system does not support the function. A SP level is required for back end.
I can access via BO Platform in Test environment, but not in Production.

My question is: What is the minimal BW version and SP requirements in BW server to use AFO via Netweaver Platform?

Any help is welcome.

Thanks.
