• Key Concepts: 
  Reference shift is a feature of Model Mix Planning (MMP) in SAP Advanced Planning and Optimization (APO). It allows users to shift the reference point of the MMP planning process from one period to another. This enables users to plan for different scenarios and compare the results. 
  
  How to use it: 
  To use reference shift, users must first define a reference period in the MMP planning book. This period will be used as the starting point for the planning process. Then, users can select the “Reference Shift” option in the MMP planning book and enter a new reference period. The planning process will then be shifted to this new reference period. 
  
  Tips & Tricks: 
  When using reference shift, it is important to remember that all data from the original reference period will be shifted to the new reference period. This includes all planned orders, production orders, and purchase orders. Therefore, it is important to ensure that all data is correct before shifting the reference period.
