“Production Schedules was kind of designed for “use up” of alternate component prior the primary component.” → can we have this same behaviour in MRP and Shop Orders?Īdditionaly, the MRP will do the calculations, but the SOR and SO Materials need to be changed by hand. So it makes a Alternate - Primary - Alternate - Primary…. until all alternates are consumed and only new parts. So each time we receive a batch of primery parts, it will shift to the primary and go back to the alternate soon after. More on this here :Įventualy, we will receive some new parts to stock, and then the MRP plays the following trick: will suggest using the primary part just received (as there is Qty on hand available), then will calculate to use the Alternate Part (when the projected qty of the primary is negative again)….

The MRP calculation will not take into account Pending Supply from the part we are phasing out (with still some pending POs that are on the way). The MRP calculation will reduce the need for the new part, taking into account the Qty on Hand of the part we want to phase out.

We are currently defining the Alternate Components with MRP Netting functionality (Include in MRP), but the MRP logic plays a trick as follows: but we would like always to consume all inventory of the old component, so that we do not leave 'obsolete components in stock'. When doing these changes, on a product structure, we increase the revision (with the new component included in the BoM). A revision change, a product improvement, a better cost, etc. normaly to introduce a new component and phase out an old component. We frequently change parts for other parts, a replacement part. Is there any way to change the MRP logic described above to push the usage of Altenate Components while there is availbaility of them? Production Schedules was kind of designed for “use up” of alternate component prior the primary component. As a general rule the alternate component(s) are processed prior the primary component.Īnd yes Production Schedules differ from Shop Order and MRP in this area. I should mention that MRP figures out in which order it should perform the netting. If there is still a net requirement at this stage, do the lot sizing and create SO/PO Requisitions (for the primary component of course).If there is excess onhand for the alternate component then plan for it :-) Net requirement will be reduced.If open supply does not cover the temporary net requirement check if alternate component can be used in the netting logic.If no or “to some extent” then check if there are any open supply order for the primary component that can be applied in the netting logic.

Does available inventory onhand cover the gross requirement?.In MRP, the logic works as Jane describes it, so for the primary component, MRP engine checks: Aviation Technical Content Manager (ATCM) 0.Projects Based (Contract/Resource Management, Project Management, Engineering Design & Deliverables) 197.Products (Manufacturing, Products, Engineering) 1684.Insights (Business Reporter and Analysis Models, EOI) 347.HCM (Human Capital Management, Payroll) 712.Framework & Experience (Infrastructure, Cloud, Integration, Dev Tools) 4357.Field Service Management (FSM) & Planning and Scheduling Optimization (PSO) 1200.Buying (Procurement, Demand Planner, ASC, SRM) 1214.
