248 MFG/PRO USER GUIDE — MANUFACTURING Ï See Chapter 2, “Product Structures,” on page 11 and Chapter 4, “Formula/ Process,” on page 43. Inventory Status Codes Assign a non-nettable inventory status code to inventories that should not be considered quantity on hand by MRP. This might include inventory to be returned to a supplier or designated as scrap or salvage. Product Structures and Formulas Product structures and formulas provide some of the information used in MRP calculations, including component quantities, lead times, and effective dates. Enter and modify product structure and formula information in Product Structure Maintenance (13.5) and Formula Maintenance (15.5). Component Quantity To calculate component requirements for planned orders, MRP multiplies each component’s quantity per assembly value by the planned order release quantity. Component Lead Time MRP determines a component’s due or required date using the scheduled release date of the parent item and the component lead time offset specified in the product structure. Example When a component’s lead time offset is 10 days, its due date will be 10 manufacturing days after the planned release date of the assembly. When it is –5 days, the due date is 5 manufacturing days before the planned release date of the assembly. If no lead time offset is specified for a component, the component release date will be the same as the release date for the parent item.
Component Effective Dates MATERIAL REQUIREMENTS PLANNING 249 MRP uses component effective dates to determine which components are required for a given order due date. Components are active beginning on the start date specified in the product structure and remain active through the stop date, the last day a component will be used. Executing MRP MRP Processing MRP reports and inquiries can optionally display item requirements summarized by week. The beginning day of the week is specified in the Summary Default field of the MRP Control File. Calculations are based on this weekly period. MRP calculates net requirements for items using three variables: • Gross item requirements are the sum of an item’s requirements from forecasts, higher level products, customer orders, service items, and intersite orders. They do not take into account inventory on hand or scheduled receipts. • Scheduled receipts for that item, including open purchase orders, open work orders with a quantity open and a status of R, and intersite requests for DRP items. • Quantity on hand from the previous period. MRP uses these three variables in the following calculation: Net Requirements = Gross Requirements – Quantity on Hand for the previous period – Scheduled Receipts MRP schedules planned purchase orders and work orders to fill these net requirements. Planned work orders generated by MRP are exploded into gross requirements for their components. This process continues until there are no more planned work orders to explode. Note MRP does not explode product structures for purchased and distribution items or components with structure code Document. Ï See “Engineering Effectivity” on page 23 for more information on how MRP handles component effective dates.
