MRP System Settings for Smoother Scheduling

BOM–Master Schedule Alignment: The “Tiny” Miss That Triggers Big Delays The worst production delays often don’t come from big crises, they come from small mismatches between the Bill of Materials (BOM) and the Master Schedule. In recent work, tightening that link alone contributed to a 10% reduction in production delays and made order execution far more predictable. Here’s how that played out behind the scenes: - The BOM was treated as the single source of truth for materials, components, and quantities required for every finished good, while the Master Schedule translated demand into a time‑phased production plan. When those two were out of sync, MRP planned the wrong items, at the wrong levels, or at the wrong time showing up as missing parts, emergency expedites, and overtime on the shop floor. -Alignment started with verifying BOM accuracy and structure so every scheduled SKU had a complete, current component list before MRP ran. The Master Schedule was then explicitly linked to validated BOMs and realistic lead times, so planned orders reflected true material and capacity needs. -Exceptions like recurring shortages and frequent reschedules were monitored and fed back into BOM maintenance and scheduling rules, turning firefighting into continuous feedback. ERP planning tools were used to simulate schedule changes and check material availability ahead of freeze periods, reducing last‑minute surprises. By treating BOM governance and Master Scheduling as one integrated discipline, not two separate tasks, production became more predictable, delays dropped, and planners were finally able to shift their time from expediting to continuous improvement. What about you: where do you see the biggest BOM–schedule disconnects in your plant? #ProductionScheduling #MRP #SupplyChainExecution #ManufacturingPlanning

MRP errors are devastating. This document contains a 21-point checklist for Material Requirements Planning (MRP): ↳ # 1 - Ensure Bills of Materials (BOMs) are complete and contain all part numbers and alternates ↳ # 2 - Set up preferred and approved suppliers with accurate details ↳ # 3 Maintain up-to-date supplier lead times for each item ↳ # 4 - Define accurate Minimum Order Quantities (MOQs) for every supplier and part ↳ # 5 - Input and validate accurate freight and incoterms in supplier records ↳ # 6 - Review and confirm open purchase orders (POs) with suppliers ↳ # 7 - Keep ready dates and ETAs (Estimated Times of Arrival) updated regularly ↳ # 8 - Maintain accurate on-hand inventory by location and batch ↳ # 9 - Track and consider inventory in transit and inter-plant transfer lead times ↳ # 10 - Always run MRP with the most updated Master Production Schedule (MPS) ↳ # 11 - Review safety stock levels to reflect true demand and supply variability ↳ # 12 - Set accurate planning horizons (short, medium, and long-term) to match business needs ↳ # 13 - Ensure item planning policies are accurate ↳ # 14 - Validate production lead times for each work center ↳ # 15 - Include alternate sourcing and dual suppliers in the system where applicable ↳ # 16 - Verify substitution rules for interchangeable parts ↳ # 17 - Incorporate shelf-life, expiration dates, and aging rules for sensitive items. ↳ # 18 - Verify exception messages (reschedule in, reschedule out, cancel, expedite) ↳ # 19 - Track planner buy reports and reconcile against supplier acknowledgments ↳ # 20 - Validate supplier confirmations (acknowledgment of PO dates and quantities) ↳ # 21 - Establish feedback loops; when MRP recommendations fail, document root causes and adjust parameters Any others to add?

Think of it as: Activate MRP → Control planning → Protect the plan → Evaluate results What this guide covers ✅ MRP Activation & Planning File – Plant-level activation (OMDU) – Planning file & Net Change logic ✅ Plant-Level MRP Control (OPPQ) – Planning parameters, number ranges – Scheduling, capacity, BOM & routing logic ✅ Special Procurement – Stock transfer, subcontracting, alternate plant, phantom items ✅ MRP Groups (OPPR) – Override plant behavior without creating new plants ✅ MRP Types – PD, VB, ROP, Forecast, MPS – Time fence, firming, consumption logic ✅ Planning Time Fence – Protect firmed plans from MRP changes ✅ MRP Areas – Storage location & subcontractor-level planning ✅ Dynamic Safety Stock – Demand-based, auto-adjusting safety stock ✅ Days Supply / Receipt Days Supply – Planner evaluation & decision support This guide helps you understand why MRP gives certain results, not just how to run it. 📌 Let’s Connect 1:1 and Accelerate Your SAP Journey -https://lnkd.in/g62RqTbB #SAP #S4HANA #MRP #SAPPP #SAPImplementation #SupplyChain

SAP Lot Size Key EX (Hybrid): The Small Setting That Drives BIG Results 🚀   In SAP, the lot size key is one of the most underrated power levers in Materials Management and MRP.   Get it right leads to a smooth flow, lean inventory, stable production. Get it wrong → excess stock, firefighting, and costly instability.   Think of it like cruise control for your supply chain: ⚙️ It decides how much, when, and how often you replenish.   Let’s break it down with two viewpoints: 🔹 Novice Planner: “I just want MRP to order what we need!” 🔹 Expert Planner: “That’s what the lot size key controls - aligning demand, ordering rhythm, and inventory.”   💧 Lot-for-Lot (EX)   “We learnt that EX is the barista style which mean every demand gets precisely the quantity required."   Now we notch it up a little bit a play around with the parameters that the systems provides us and see how we can use them differently.   Now we need to keep in mind that we have a procurement department and it is more economic for us to order a minimum quantity. Let`s say sometimes we need more than that and then there is a rounding value.   We create an example in which we have a MOQ of 2500 ltr and a rounding value of 500 ltr   Example: Requirement = 4,524.024 ltr → Stock = 29.23 ltr → Order = 4,500 ltr (mimimum lot size 2,500 ltr plus 4 x rounding value of 500 ltr) → Projected stock 5.128 ltr ✅   Further in our MD04 we have a new total requirements = 375.761 ltr and we see that the MRP proposes to order 2,500 ltr (which is our miniumum lot size that we set to 2,500 ltr), and MRP now covers more than the immediate need → leading to 2,129.397 ltr surplus.   Small parameter change → visible inventory impact!   🔍 Pro Tip from the Field   ➡️ Use MD04 as your real-time cockpit. Watch how different keys reshape your stock curve, service level, and working capital. Sometimes, the fastest value unlock in supply planning is simply selecting the right lot size key and its associated values.   Let’s grow together: connect with me here on LinkedIn, share your thoughts in the comments, and feel free to reach out if you’d like to collaborate or discuss this topic further. 💬🤝 ================================================ 👋 Hi, I'm Sascha a supply chain expert with 10+ years of leading pharma & biologics operations in Switzerland.
