This time I would like to dig into my slightly disappointed case I mentioned in my last post. When 3 way match well-functions as we hope, it is just great because it recodes transaction so clearly on the system and book.

Unfortunately our lives are different. We face a lot of unexpected deals such as special discount / up due to sudden FX fluctuation and order quantities don’t match inspection amount because of the lack of raw material, it is due to the nature of product though. The problem is that no one advise in advance….just headache!.

Standard cost accounting teaches us to manage these kinds of unmathc and changes as price variance or qutitiy variance and it will help to measure cost efficiency. SAP can take care of these variance but it is necessary to define what variance we should monitor in advance.

To modify PO, manual adjustment of 3 way matching should be required so we assumed to make things clear to handle all of them as price / quantity variance. As you know, someone is always so nervous about this kind of stuff…. it was too difficult to make everything go straight forward.
