Multi Method Supply Planning in SAP APO [EPUB ebook] 

Which supply planning method meets your company’s business requirements? The answer might surprise you! Here’s the truth: There is no one right supply planning method for all situations, even within one company! In fact, it is unnecessary to choose only one method, and using multiple supply planning methods is feasible and in most cases, has many advantages over using a single method. This book explains why no one supply planning method meets all requirements, and lists the many benefits of using multiple supply planning methods. It gives practical advice about selecting supply planning methods and method modifiers, and goes deep into the 'how to’ of implementing mixed methods.
