SAP SCM Reviews & Insights

SAP Supply Chain Management solution's two parts were implemented at our organization.
1) Advanced planning & optimization (APO)
2) Event Management (OER - object event repository)
Both were being used by different departments, and not by the whole organization.

APO solution offers integrated functionality for demand, supply, and production planning – as well as global available-to-promise (ATP). It provided functionality for forecasting and demand management with efficient supply network capabilities.

EM offers solution to track object, real-time status, location and expected/unexpected event for within supply chain of our organization.

For retail, logistics and manufacturing industry business cases, I think SAP Supply Chain Management is very well suited.
GATP backorder processing, forecasting, scheduling, product availability check, rule based ATP checks are specific scenarios in which it is well suited.

SAP SCM product suite especially APO (Advanced Planning and Optimization) is used for carrying out planning and scheduling in the manufacturing business. Demand Planning helps in creating a statistical forecast for different product lines based on past history, promotional events, consumer trends and competitive intelligence.

It is a great product suite where you can use many of the out of the box functionalities with minimal customization. For example managing multiple product configurations using variant configuration, using the Integrated Product and Process Engineering function for the automobile industry is great to use and is applicable to many organizations. For paper and metal industry though, it may require extensive customization including the creation of custom heuristics for scheduling, integration with third-party enterprise applications.
