Anele Daniels

Project Manager

I bought this book and its been very helpful not only around Production variance analysis but mostly in understanding Product Cost Planning. One of the best features on the book is the way John that projects the overview flow of activities from various modules (PP/SD/MM/CO) then start breaking them by sections. I can’t wait for the Product Cost Controlling book.

Russ Gandy

SAP Cost Professional

John Jordan has authored an excellent book on SAP Product Costing. I have read his book "Production Variance Analysis in SAP Controlling" cover to cover more than once and use it as a reference often. To me it is more than a book on variance analysis as it also provides great perspective on the product costing process.
