SAP APO Supply and Demand Matching - SAP APO

What is SAP APO Supply and Demand Matching?

Supply and Demand Matching has two functions which are main function Capable-To-Match (CTM) and extra function for distributing stocks. In APO, cross plant supply strategy is provided by SDM component −

  • Production Planning and Detailed Scheduling (PP/DS)
  • Supply Network Planning (SNP)

Capable-To-Match (CTM) Function

This function is for performing finite planning of demands in the process of supply chain. For SNP and PP/DS data types this is used. It has interest in planning from mid to long-term.

Go to Advanced Planning and Optimization → then to Basis Settings → then to Optimization → then to Basic Functions → and to Maintain Master data for optimization server.

Under CTM, below functions are done −

  • Other resource location can be evaluated for fulfilling the demands of a specific product whenever the demand is not fulfilled by that resource.
  • Demand Prioritization: Demands are prioritized as per our wish.
  • For CTM planning, consistency run can be executed for the master data check.
  • It is used to select the master data and selecting the order.
  • Supply control is performed using CTM. It also helps in avoiding the supply of products which are oversized.
