A master plan; warehouses marked Required in MRP

Before you start​

  • A Master Planning document.
  • Warehouses marked Required in MRP (Warehouse).
  • Safety Lead Time, Minimum Order Quantity and Order Multiple on the items, if wanted.

Steps​

  1. Open Material Requirement Planning, pick the Plan and the Transaction Date.
  2. Tick Validate Available Stock, and Create Purchase Requisition and/or Create Manufacturing Order. Fill Purchase Reason and responsibles.
  3. Create. The requirement, summary and order lines fill in.
  4. Save. Requisitions and Planned manufacturing orders are raised.

Check it worked​

  • Draft purchase requisitions appear in purchasing with the MRP number; Planned orders on the Manufacture Order list.

If something looks wrong​

  • "Warehouses are not marked as Required in MRP" Mark them on the warehouse.
  • "There is no BOM of ... found in Transaction Date ..." A made component needs a valid BOM.
