Extract account Based COPA from R/3 using Business Object data services

Hello,

We have a requirement to extract Account Based COPA from SAP R/3 to Teradata using Business Objects data services.

I have read couple of white papers which give information on Rapid Marts( which are built in packages) already available for some applications like inventory, GL, AP, AR etc. But I could not find anything for COPA.

Would anyone give me any information on how to use BO data services for COPA?

Also if there is no rapid mart available for COPA, does anyone know how to create custom data marts in BO Data services?

Is there any document available on this?

Please respond as soon as possible.

Thanks.
