Need to Look up DSO1 Data to DSO

Hi Experts,

I have TWO DSO's

DSO -1 had Sale Doc, item and other information.

DSO -2 has Coniditon Type, Condition values

Now I need develop another DSO that should have all the information from DSO1 and two key figures that needs be derived from DSO-2 as look up.

value1 : Five conditions Types and associated condition values

Value 2 : Two Conditions Types and associated values

I am trying to get this through End Routine but some how it is not working, Could some one kindly help me on this.

Thanks,

Sekhar
