The MPS master production schedule drives MRP net requirement calculation. With multi-level BOM explosion, deduction of on-hand inventory and in-transit purchases, and consideration of safety stock and lead times, the system automatically generates purchase and production suggestions — putting an end to the inefficiency and errors of calculating materials in Excel.
The entire chain from MPS to purchase order is automated
Generate a rolling monthly/weekly MPS from forecasts plus sales orders, balanced against rough-cut capacity to align supply and demand.
The MPS is exploded through multi-level BOMs into gross requirements for materials at each tier, including scrap factors and substitute-material relationships.
Gross requirements are netted against on-hand inventory, in-transit purchases and allocations to other work orders to yield the true net requirement.
Back-calculate order dates from material lead times, with a safety-stock protection strategy to prevent material shortages.
Net requirements for purchased materials automatically generate purchase suggestions, split by supplier, unit price and minimum order quantity.
Net requirements for in-house materials generate production suggestions that, once merged with work orders, are dispatched to APS.
MRP is not just about "calculating how much is missing," but about "when materials arrive and whether everything is kitted to start." SBK MRP pushes kitting validation down to the operation level, ensuring the materials needed before each operation are already in the shop-floor warehouse.
Aggregated by supplier · MOQ / EOQ applied
What MRP produces are "suggestions," but what buyers need are "orders ready to place." The system automatically consolidates suggestions by supplier strategy, merges unit prices, accounts for minimum order quantities and transport batch sizes, and converts them to purchase orders with one click.
Incremental triggers this run
The traditional approach runs MRP once at the start of the month, only to become outdated the moment orders change mid-month. SBK MRP supports a dual mode of "on-demand trigger + scheduled refresh," where order changes, inventory changes and purchase arrivals can all trigger an incremental calculation.
Machinery equipment with 8-level BOMs and 3,000+ parts — MRP produces net requirements and purchase suggestions in minutes, freeing up the PMC team.
200 part numbers per day; MRP runs every 4 hours, combined with the shortest purchase lead times to keep the line running.
Calculate requirements by "recipe batch" — main ingredients + auxiliary materials + additives + packaging together — ensuring the next batch is fully kitted.
OEM rolling demand drives MRP, pushing inventory safety factors to the minimum and halving working-capital tie-up.
