Demand Driven MRP (DDMRP) is a great trigger to buy/make/distribute in the short-term. But what occurs over the next 1 to 12 months? Supply chains need the visibility over this period of time as well. Can we still use DDMRP? In short, yes!
What is DDMRP used for?
DDMRP is the operational component of the Demand Driven Adaptive Enterprise (DDAE) to deliver inventory and customer service benefits. For further case studies and education, please read this article on Demand Driven MRP & The Demand Driven Adaptive Enterprise.
DDMRP is an unconstrained order release process based on inventory buffers within the Decoupled Leadtime (DLT). These buffers can be sized using historical demand and/or future demand. This will ensure the buffers are dynamically sized. However, DDMRP has no visibility of the capacity available to supply those buffers. Demand Driven S&OP (DDS&OP) is vital to allow us to carry out a supply and demand reconciliation to recommend buffer adjustments to reduce these risks.
The relevant range of Demand Driven S&OP is everything outside the DLT up to approx. 1-2 years. DDS&OP also reviews historical performance of the buffers and ensures the key inputs to buffer sizing (Average Daily Usage (ADU), Red zone, Green Zone) are optimal.
A SAP IBP solution
The Olivehorse DDS&OP solution is built within SAP IBP and therefore seamlessly integrates with SAP Demand Driven Replenishment (DDR). The flexibility of SAP IBP plus the Supply Optimiser allows us to consider capacity constraints, material lead-times across the End-to-End network and calculate buffer adjustments outside the DLT.Read Article
