Read Purchase data using Report painter with CCSS structure

Hi

I'm triying to set-up a simple Budget by material procedure using Rosurces defined as material and KP06 to plan Qty and Values.

All works fine.

Later I need to write a report for Compare Planned vaues and Effective values at material (resource) level.

Unfortunately resource can be used only for planning, so none Effective values is available in CO.

I thought to write a Report using Report painter and library 1VK (CCSS structure) for planned values and import from a LIS table the effective values (Ordered, Invoiced) directly from Puirchasing environment.

Is it possible by using exit or other tools, import LIS data into a CO Report painter program ???

Thanks in advanec for your help.
