how to define APOQuota Arrangement in Quantity, not percent?

[jilleedgreat]

Hello SAP Experts,

Is there a way to define QA by quantity and not by percent. My client wants to get 25,000 CS worth of Preq from vendor A monthly, then the rest will be provided by vendor B. In this occasion, percent is not applicable.

Also, can you explain in simple terms how Reqt grouping, Req Split, Split Qty and Quota Base Qty works?

Your help is very much appreciated.

thanks!!
