PPV report or functional Specification

Dear Friends,

I tried but did not find any standard Purchase Price variance report. My client's report requirement is :

PO, Mateial, Std Price, Std Cost , Actual Price, Actual Qty, Actual Cost, Batch, Vendor..............

All information I collected to develop a report except actual Price and Actual Cost.

My client is Indian and we are using CIN. In PO there is basic rate/cost but final/other rate are deriving from MM condition i.e frieght/insurance, excise etc.....

I am not able to find field/fields from where I can get final actual cost of PO or final actual price.

Although in table KONV I can total value of PO but how can be linked , i dont know.

Requesting you please provide me your guidance or if any body has functinal specification and can send to me, please send (my id is in my profile).

It would be great help.

Thanks

Ravi
