how to have information about purchasing documents and service packages

Hello,

In a BI report, I want to have all Purchasing Document by service package. All data are in tables ESSR and ESLL.

I looked the DSO 0PUR_O01 but there is no information about the service package. I also have the cube 0SRV_C01 but I did not have the information about purchasing documents.

What can I do to have all those information on the same cube?

Thanks!
