Sales Info SystemInformation contains total sales orders already obtained,incoming sales orders, pending sales orders product wise,
customer wise, region wise.
ForecastingBased 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.

MRPThis 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.
MPSPlanning of items that greatly influence the companys 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 Val idity 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 BOMs to represent different objects; for example:
Material BOM -- structure ofproducts manufacturedEquipment BOM -- structure ofequipment for plant maintenance
Document BOM -- structure ofdocuments such as drawings (3.0)BOM Group is a collective number for all BOMs in a group which allows for one
or several similar products to be described under one number.
AllAlternatives of a multiple Bill of MaterialAll 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
8/3/2019 Sap Production Planning (Old)
26/100
Technical Type the system distinguishes BOMs 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
8/3/2019 Sap Production Planning (Old)
27/100
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 componentNon-stock Items -- material not stocked - with or without a material numberVariable-size -- system calculates the quantity required using formulasPM Structure Item -- used with plant maintenance equipmentDocument Item -- used with Document BOMs
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

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 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 fordifferent 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
8/3/2019 Sap Production Planning (Old)

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 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

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

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

Material Master MRP 1Key Fields
Scheduling Parameters
Planning Time Fence: defines a period during which MRP/MPS will notautomatically add or reschedule orders
Scheduling Margin: controls the release period, opening periodfor a material
and scheduling floats for production
Release periodis thenumber of working days in the release period
Opening period is the number of working days between the order creation andplanned 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
