Mapping dataSource to InfoSource (BI 7.0)

Dear Experts,

I am implementing Costing-Based CO-PA and  have created the datasource.

the standard cube(0COPA_C01) has activcated as well.

When I am trying to do transformation from datasource to infosource,

I think it should auto create the mapping infoobject, but it doesn't....

Do I need to key in or create the everyone mapping infobject manually? (I don't think it should be do this way >"<)

Please kindly help me how to solve this problem..

Thanks a lot.
