The master scheduling logic within Dynamics AX provides a key tool for coordinating supply chain activities in manufacturing/distribution firms. However, many users have struggled with effective use of master scheduling. The difficulties often stem from the large number of variables that must be considered, and the often confusing aspects of Dynamics AX. This two part session summarizes the major S&OP scenarios for using master scheduling logic, and focuses on a few basic scenarios. It provides a detailed walk-through of the key screens and fields related to performing the master scheduling task, the use of key outputs, and the key information impacting master scheduling logic. The detailed walk-through will reflect AX 2012 R2 capabilities, but audience questions about previous AX versions will also be addressed. Part I of II.
