Step 1 Detailed Instructions
1) Release Order for 500 LB of Dough
NRG-A 2) Issue goods to production order (oats,
wheat germ, etc.) from SLOC 100 3) Confirm
production of 500 LB (accounting) 4) Receive 500
LB of Dough NRG-A into SLOC 200
4
Step 2 Follow the Pattern
1) Release Order for 7 Cases of Dough
NRG-A 2) Issue goods to production order (500 LB
of Dough NRG-A) 3) Confirm production of 7
Cases (accounting) 4) Receive 7 Cases of NRG-A
into SLOC 300

Functions of Production Orders

• Status Management Tracking, User-defined status
• Scheduling
• Calculation of Capacity Requirements (detailed)
• Costing
• Availability Checks (material, capacity, PRT-
  production resources and tools)
• Printing of Paper Orders/related documents
• Assembly drawings and instructions
• Inspection instructions
• Storage regulations
• Material Staging withdrawal of materials used in
  production, e.g. components and sub-assemblies

6
Functions of Production Orders

• Confirmations quantities, activities, times
• Goods receipt receipt of completed materials
• Period-end closing Process cost allocation,
  overhead costs, surcharges, WIP calculation,
  variance calculation, order settlement
• Archiving and retrieval
• Many more rework, serial numbers, as-built,
  quality control, etc.
• Production Orders capture actual datacosts,
  dates, etc.

7
Planned Orders vs. Production Orders

• Planned Orders are for PLANNING
• Production Orders are for EXECUTION

8
Master Data for Production Orders

• Master Data is data that does not change
  frequently
• Master Data for the production order comes from
• Material Master
• Bill of Material (BOM)
• Work Center
• Routing
• Production Resources/Tools (PRT)
• Materials like gages, fixtures, test equipment
• Can also be items like drill bits that can be
  consumed in production but arent consumed INTO
  the product
• Most Production Order data comes from BOM and
  Routing

Production Order Cycle
10
Production Order Cycle

• The Production Order goes through many
  activities, many of which can run automatically
  or in the background
• Cost Object Controlling activities (WIP
  determination, variance calculation, and
  settlement) are periodic and usually performed in
  the background

11
Methods of Creating Production Orders

• Direct (manually)
• From planned order (created by MRP)
• Order by order an individual planned order is
  turned into a production order
• Mass processing a group of orders is processed
  in a batch
• For sales order (can be automatic)
• For rework

12
Scheduling

• MRP calculations determine Basic Dates
• Basic start date the earliest possible start of
  production
• Basic finish date the latest possible date by
  which production has to be finished
• The opening period (planned open date to basic
  start date) is the time required by the MRP
  controller to convert the planned orders into
  production orders or purchase requisitions
  (defined in scheduling margin keyspecified in
  material master).
• Basic dates are calculated using in-house
  production time (or replenishment lead time for
  purchased components) and backward scheduling.

Status Management

• Status Management is one tool that can be used to
  manage released production orders
• A status can allow, allow with warning, or block
  a business transaction
• Two status types are available
• System status internal, predefined, fixed
  number
• User status freely definable, set by user
