Net value confirmed in POR in Classic scenario

hi,

I have seen in the EBP-SUS scenario , it is possible to compare

purchase order and purchase order response which the supplier had sent

1) in the case of MM-SUS scneario , as far as i know , there is no point where you can compare --> purchase order and purchase order response.

2)there is also possibility that , the purchaser in R/3 mentions an toleranc limite -->if the changed date , quantity , price from the supplier is beyond a certain specified tolerance limit , system would not post the

IDOC and follow-on document will not be created in R/3.

3) this way purchaser makes sure that the supplier does not change the values beyond a certain limit.

4) you can also check --> for the item changes --> in the R/3 purchaser order --> to check wether the changes supplier has done are recorded (or) not... , i am not sure about this though...
