Data target problem

Hi,

I am learning BW now.

I am in an attempt of doing activation of Business content(area :personnel development-infosource (0HR_PA_PD_2),data source(0HR_PA_PD_2)),while doing I am getting the following error message;

"No data targets have yet been updated from this request

(It might be that no data targets have been defined or selected yet)

Do you really want to load data?".

If anyboday has the doc for the above problem please send me the doc to mjaheer@hotmail.com.

With Regards,

Jaheer
