Manufacturing Planning and Execution Sales Info System Information contains total sales orders already obtained,  incoming sales orders, pending sales orders – product wise, customer wise, region wise. Forecasting Based on the past history of consumption, a forecast of the sales figures for a product can be made. Future projections are made using one of the Statistical forecasting methods. COMPONENTS
Manufacturing Planning and Execution Sales & Operations Planning Higher level planning i.e.overall planning at company level Yearly/Half yearly/Quarterly Planning Demand Management Management of Requirements Requirements can be from sales forecasts, sales orders,etc. CO/PA Projections will be based on the company’s future projection of costing and profitability analysis.
Manufacturing Planning and Execution MRP This is the total planning of all the components taking into consideration the existing requirements and stocks. Creation of purchase requisitions, production orders,etc. Final step in the planning process. MPS Planning of items that greatly influence the company’s profits or consume critical resources/dominate production processes. After the production plan of these critical items are firmed up, the planning of other components are taken up.

Bill of Material Validity Area of Validity  – The same Bill of Material can be allocated to several plants. Before you can allocate the BOM to a different plant, the material must exist at the new plant, the unit of issue on the BOM item must be the same. Validity Period  (Valid from/to dates) Becomes effective with the valid from date The validity date is determined by the system automatically to be either the next effective from date, or 12/31/1999.

Bill of Material Glossary BOM Category  –  categorizes BOM’s to represent different objects; for example: Material BOM -- structure of  products  manufactured Equipment BOM -- structure of  equipment   for plant maintenance Document BOM -- structure of  documents  such as drawings (3.0) BOM Group  – is a collective number for all BOM’s in a group which allows for one or several similar products to be described  under one number. All  Alternatives   of a multiple Bill of Material All  variants   of a variant Bill of Material BOM Usage  – special view of the BOM  which represents a specific area of the company in which the BOM is used; for example, Engineering, Production, Costing, Sales, Plant Maintenance The BOM Usage allows different views to exist without  separate BOM’s for each usage.
Technical Type  – the system distinguishes BOM’s according to whether they represent product variants or production alternatives. If you create a variant for the BOM,the system marks it as a  Variant Bill  .  If there is more than one alternative for a material, the system marks the BOM as a  Multiple Bill . Bill of Material Glossary (cont.) BOM  Validity   – Bills of Material are valid over an area and effectivity period. Area of Validity -- identifies which plants the BOM has been allocated to Validity Period -- identifies the from and to effectivity dates.  The default to date is 12/31/9999
Item Category   – When you enter a new Bill of Material item, an item category must be assigned. It has important control functions such as: Screen selection  Specific processing, such as material number required, negative values supported. The Item Category cannot be changed once set.  It must be deleted and re-added. Sizes are maintained for variable-size items Item categories include: Stock Items -- material in stock as a component Non-stock Items -- material not stocked - with or without a material number Variable-size -- system calculates the quantity required using formulas PM Structure Item -- used with plant maintenance equipment Document Item -- used with Document BOM’s Sub-Items   – are typically used to represent different installation points for partial  quantities of an item. In assembling resistors on a printed circuit board, the installation points are described. There is no logic related to sub-items Bill of Material Glossary (cont.)

The Planning Concept in SAP SOP MPS Planned Independent Requirements Customer Independent Requirements Requirements (Orders) from SD Module Offset Keep Balanced Order Proposals MRP Planned Orders Production Orders Purchase Requisitions Demand ie Requirements Order proposals, planned orders etc are created and adjusted by running the MRP or MPS programs. Sales Plan Production Plan
SOP specifies sales quantities for the long and intermediate term to roughly assess the feasibility of sales and operation plans Sales and Operations Planning at the Product Group or F/G level Materials may be planned together in Product Groups Sales quantities are determined for future periods Production quantities are then determined on the basis of sales  Sales and Operations Planning Functions
MRP II is concerned with integrating individual plans within a supply chain Profitability Analysis – Revenue and Sales Plans Sales and Operations Planning – Sales and Production Plans Master Planning – Demand Program and  Master Schedule Material Requirements Planning – Dependent Requirements   and  Procurement Plan Sales and Operations Planning  – Planning Levels
Step 1  – Sales Planning of Future Sales Quantities Copy in from Sales Information System or Profitability Analysis Automatic forecast based on historical factors Manual entry of sales quantities Step 2  – Production Planning Synchronize production plan with sales plan Stock level equal to zero Specify a target days supply by period Specify a target stock level by period Enter planning data manually Sales and Operations Planning – Steps
Step 3  – Disaggregation of Planning Values Determine the sales and production quantities of product group members  Modify the disaggregated sales planning data and create a production plan for each member Step 4  – Transfer of Planning Values to MRP Pass the planned sales and production quantities as independent requirements to demand management If product group data is transferred,  the system automatically disaggregates the planning data to the finished product level Sales and Operations Planning – Steps
Sales and Operations Planning – Product Groups A Product Group brings together materials according  to some criteria such as similar type or manufacturing process. Link material master data with product groups Materials and product groups can be members of more than one group for different planning scenarios Assignment of members from different plants to the same product group for cross-plant planning A product group may have a different unit of measure  from its members e.g. aggregate in cartons vs pieces Proportional factors for disaggregation - how  the product group quantitiy is distributed to its members Supports production versions for a material or group Supports multi-level product group hierarchy  Graphical support of one or more levels
Sales and Production Planning is carried out using a Planning Table which shows the stock level that results from the sales and operations planning for both materials and product groups The Planning Table is divided into: Sales Quantities Production Quantities  Target Day’s Supply and Target Stock Levels Sales and Operations Planning – The Planning Table
Sales and Operations Planning – Creating a Sales Plan Manual Data Entry and Distribution Functions Entered directly into the Planning Table as a % or qty Copying Data from Sales Information System Planned order, invoiced or delivery quantities The planning data is aggregated across all materials in the group Copying from Profitability Analysis Quantity and performance measures Copying the Forecast Aggregates the consumption values for all the materials in the product group
Sales and Operations Planning – Creating a Production Plan Determine the quantities to produce to meet the sales plan Synchronize to the Sales Plan  – the system copies the sales quantities into the production quantities Zero Stock Level  – Use existing stock to cover sales quantities. When used up, production quantities will synchronize with the sales quantities Target Stock Level  – The system determines production quantities based on sales and target stock levels Target Days Supply  – Coverage is expressed in days
Sales and Operations Planning – Disaggregation Functionality is based on proportionality factors of product group members The result of disaggregation is the sales plan of its members Strategy parameters are used to create the production plan from the sales plan on to a product group member Disaggregation can be carried out for the product group or for selected members only
Sales and Operations Planning –  Transferring Data to Demand Management Transfer a single-level product group (multiple) or individual material (single) Independent Requirements Parameters  Specify Requirements Type Version Number Limit scope of the time period

Make product for stock in expectation of customer sales Plan using planned independent requirements for “anonymous” make-to-stock  production. Use Net or Gross Requirements Planning Net Requirements -- includes warehouse stock, planned issues and receipts Gross Requirements -- excludes warehouse stock.  Just includes planned and open orders Example is a shelf stock item such as a bike accessory light Planning Requirement Type is LSF - make to stock which is used in the   planned independent requirements transaction Sales Order Requirement is KSL - which is sale from stock Planning Strategy – Make-to Stock
Sale from stock Planning Production Push Warehouse Stock  Finished Product Strategy:  Make-To-Stock Production Example: Common shelf items such as a bike accessory (light)
Make product in expectation of customer sales Plan using planned independent requirements at finished goods level to drive demand to long lead time components Typically there is a longer lead time to produce than the customer is  willing to wait for Sales orders consume the planned independent requirement quantities Planned quantities that are not consumed by sales orders result in excess stock Example is a long lead time custom product Planning Requirement Type is VSF –  planning with final assembly Sales Order Requirement is KSV –  which is sales order with consumption Planning Strategy – Planning with Final Assembly
Sales Order Planning Production Push Warehouse Stock  Finished Product Example: Custom furniture such as a cherry table Final  Assembly to Sales Order Purchase Produce MRP without reference to sales order Planned Independent  Requirements Strategy: Planning with Final Assembly
Planning Strategy – Planning Without Final Assembly Final assembly is initiated by the customer sales order Stop production at sub-assembly level Final assembly pull Example is automobile assembled with unique combination of features (sub-assemblies) Planning Requirement Type is VSE -- planning without final assembly Sales Order Requirement is KEV -- independent customer order with consumption
Sales Order Planning Warehouse Stock  Finished Product Warehouse Stock Assembly 01 Warehouse Stock Assembly 02 Example: Option oriented product such as a car Stop at level Planned Independent  Requirements Assembly when  Sales Order  Scheduled Purchase Produce Strategy:  Planning Without Final Assembly Production Push Final Assembly Pull
Planning Strategy – Planning with Planning Material Planned independent requirements of Planning Material initiate procurement of the planning bill components  Sales orders for the final assembly create planned orders of the finished product and reduce planning quantities for the planning material Possible to plan a family of products from forecast placed on the planning bill.  The planning bill details, through percentages, the quantity required for common parts Example is a bike with common sub-assemblies used in many finished items  Planning Requirement Type is VSEF -- planning with planning material Sales Order Requirement is KEVV -- independent customer order with planning material
Sales Order Planning Customer Stock Finished Product Planning Material Warehouse Stock Assembly 01 Warehouse Stock Assembly 02 Example: Bikes with the same features except for the color Purchase Produce Note:  Percentages drive lower level demands for sub assemblies Strategy:  Planning with Planning Material Planned Independent Requirements Production Push Final Assembly Pull
Sales Order Warehouse   Stock  Finished Product Example: Combine customer orders for the same item Strategy:  Production by Lot Size Production by Lot Size Pull
Planning Strategy – Make to Order Production Sales orders are planned according to sales order number Produced quantities for each sales order are managed individually Production and procurement costs are managed in either a settlement order or a project Example is a custom product with a unique structure such that it only applies to a particular customers order Sales Requirement Type is KE -- independent customer order without consumption
Sales Order Warehouse Stock  Finished Product Example:  New machinery Strategy:  Make-To-Order Production Production by Lot Size Pull

Material Master – MRP I Key Fields Basic, General, and Lot Size Data Procurement Type  indicates if the material is externally procured, or produced internally or both. Special Procurement   identifies special planning rules which may be used for in-house production or external procurement MRP Type  determines how the material is planned such as MRP, MPS, or consumption based planning Material Lead Time   identifies for material planning the planned delivery days or in-house production days Lot Size  determines which lot-sizing procedure the system uses to  calculate order quantities
Material Master – MRP 1Key Fields Scheduling Parameters   Planning Time Fence:  defines a period during which MRP/MPS will not automatically add or reschedule orders Scheduling Margin:  controls the  release period, opening period  for a material and  scheduling floats  for production Release period  is the   number of working days in the release period Opening period is the  number of working days between the order creation and planned start date Order floats  allows for safety margin before and after production Planned Delivery:  lead-time for purchased material In-house Production:  lead-time for manufactured material GR Processing Time:  goods receipt processing time Example: dock-to-stock time
Material Master – MRP 2 Key Fields Availability Check  indicates whether the system generates individual or summarized requirements for sales orders for this material and for planning, which MRP items the system includes in the availability check. Mat./PPC Status  is used to limit the usability of materials for certain activities such as, purchasing, bills of material
Material Master MRP 3 Key Fields Independent Requirements Consumption Mode:  controls consumption of planned independent requirements by customer requirements Selections: backward, forward, or both Consumption Periods Backward/Forward:  specifies the number of periods of forward or backward consumption Used in conjunction with consumption mode Storage Location MRP MRP Indicator:  determines whether or not requirements, for a specific storage location, are planned separately from the overall plan Reorder Level:  used for storage location MRP Replenishment Quantity:  used for storage location MRP
MRP Types VB VM VV PD M0 Manual Reorder Point Planning : MRP  produces order proposals when stock falls below a “reorder point”. The reorder point and safety stock levels are entered manually Automatic Reorder Point Planning : The reorder point and safety stock level are calculated based on the forecast results Forecast Planning The latest forecast is copied as requirements which are used to create order proposals Deterministic Planning MRP  produces order proposal(s) to match the exact quantity of the requirements based on independent and dependent demands Master Production Scheduling Similar to PD but used for master schedule items
Lot Sizing Static Periodic Optimum (Cost ) Lot for Lot Fixed Lot size Replenish up to maximum stock level Daily Lot size Weekly Lot size Monthly Lot size Flexible period Lot size according to planning calen. Part period balancing Least unit cost procedure Dynamic Lot size creation Groff reorder procedure
MRP:  Static Lot Sizing Lot for Lot Order Quantity: Shortage Quantity  =   Ordered Quantity Replenishment up to Maximum Stock Level: Stock required to achieve maximum stock level set in the material master Order  Quantity = Material  Fixed Order Quantity = Shortage Quantity Order = Fixed Order Quantity If Fixed Lot Size: Shortage Quantity  > Fixed Order Quantity If Order Order Order
Carrying Out the Planning Run Total Planning  – All materials in a given plant All materials are reviewed by MRP regardless of activity Only the materials in a plant that have  undergone a change relevant  to planning  since the last planning run (net change planning)  Planning Interval  – Limiting the MRP Planning Interval Time Planned requirements and supply order receipts example: 100 days MRP Planning Horizon
Planning Run Options for Automatic  Creation of Requisitions and Delivery Schedules MRP Control Parameter:   determine whether or not MRP will automatically create requisitions or delivery schedules Options are: Do not automatically create.  Only create planned order Automatically create within the opening period Automatically create for the entire planning horizon Opening Period Parameter:   allows the user to take advantage of MRP’s automatic creation features while retaining control over the number of open purchasing documents

    Bill of MaterialGlossary BOM Category – categorizes BOM’s to represent different objects; for example: Material BOM -- structure of products manufactured Equipment BOM -- structure of equipment for plant maintenance Document BOM -- structure of documents such as drawings (3.0) BOM Group – is a collective number for all BOM’s in a group which allows for one or several similar products to be described under one number. All Alternatives of a multiple Bill of Material All variants of a variant Bill of Material BOM Usage – special view of the BOM which represents a specific area of the company in which the BOM is used; for example, Engineering, Production, Costing, Sales, Plant Maintenance The BOM Usage allows different views to exist without separate BOM’s for each usage.
  • 26.
    Technical Type – the system distinguishes BOM’s according to whether they represent product variants or production alternatives. If you create a variant for the BOM,the system marks it as a Variant Bill . If there is more than one alternative for a material, the system marks the BOM as a Multiple Bill . Bill of Material Glossary (cont.) BOM Validity – Bills of Material are valid over an area and effectivity period. Area of Validity -- identifies which plants the BOM has been allocated to Validity Period -- identifies the from and to effectivity dates. The default to date is 12/31/9999
  • 27.
    Item Category – When you enter a new Bill of Material item, an item category must be assigned. It has important control functions such as: Screen selection Specific processing, such as material number required, negative values supported. The Item Category cannot be changed once set. It must be deleted and re-added. Sizes are maintained for variable-size items Item categories include: Stock Items -- material in stock as a component Non-stock Items -- material not stocked - with or without a material number Variable-size -- system calculates the quantity required using formulas PM Structure Item -- used with plant maintenance equipment Document Item -- used with Document BOM’s Sub-Items – are typically used to represent different installation points for partial quantities of an item. In assembling resistors on a printed circuit board, the installation points are described. There is no logic related to sub-items Bill of Material Glossary (cont.)
