2. AGENDA Quantity Modifiers Order Policy Codes How are they used
What are the results
Order Policy Codes
How do I best determine which order policy code to use?

3. MRP Steps
Gather all requirements for an item and sequence requirements by date
Net Requirement quantities against available inventory and open orders; recommend expedite/defer where due dates do not match requirement date
Plan orders where there is not enough available/on order
Calculate start date of planned order

4. Order Policy Codes
Quantity modifiers
Order Points

5. Planner
Order Point, Safety Stock & Fixed Order Qty.

6. Order Policy Code
Quantity Modifiers
Shrinkage %

7. Order Quantity Modifiers
MRP/AVP calculates what Quantity to order by referring to modifiers in the Item Warehouse record. Operates for MO or PO.
To consider:
a price break: Minimum
a handling situation: Multiple
a constraint situation: Maximum

8. Minimum Order Qty
If less than minimum is needed, planned order adjusted upward to the minimum quantity by MRP/AVP
Such as:
Vendor specifies qty for price break
Vendor will not produce less than this quantity
Manufacturing carrier quantity or other EOQ
Setup control

9. Multiples – A dozen eggs!
MRP/AVP adjusts the planned order quantity
Adjustment made after considering the minimum criterion such as:
12 to a box
50 per tub
186 per plating carrier

10. MRP issues a warning message with the planned order
Maximum
MRP issues a warning message with the planned order
AVP breaks the planned order quantity to the Maximum
Use for:
Maximum per shift
Truck load quantity
Can release over the warning
Use to detect problems

11. Quantity Modifier Set up

12. Shrink
If there is an expected loss when the item is built/purchased, Shrinkage % will increase the planned order quantity
Shrink does not affect cost or allocated quantities, only MRP planned orders
Do not use Yield in the routing and shrink or you will double the loss calculations

13. Questions?

14. Order Policy Code
The key to telling MRP/AVP how to plan orders and how to keep inventory levels and costs under control!
Parameters affected:
# of orders placed
inventory carried
resulting cost to carry
shop load
Most of all: INVENTORY COSTS
Best described using case studies

15. Order Policy Codes Code Used By Meaning:
MRP will generate planned orders and quantities based upon the Order Policy Code for that item!
Code Used By Meaning:
A MRP Discrete (Lot for Lot)
B IM Order Point, Order Quantity (EOQ)
C IM Order Point, Order Up To Level
D MRP Fixed Order Quantity
F MRP Part Period Balancing - Standard Costs
G MRP Time Periods of Supply
H MRP Order Discretely Above a Fixed Quantity
I MRP Part Period Balancing - Current Costs
Z MRP User Defined

16. Order Policy Code B, Order Point with EOQ
Ignored by MRP/AVP, planned with reorder report/Browser
When item availability goes below the item’s order point, and order is placed
If Order Point and/or Fixed Order Quantity fields are zero in the Item Balance record, a suggested order point is calculated
Suggested order quantities are printed on the Inventory Reorder Report/or Browser

17. Order Policy C-Order Point, Order Up to Level
Ignored by MRP/AVP, planned with reorder report/Browser
Similar to Code B but order is placed for difference between availability and the amount of inventory to be maintained.
The amount of inventory to be maintained is placed in the Fixed Order Quantity field.
If Fixed Order Quantity is Zero, an EOQ is calculated.

18. Order Policy Code “A”- Discrete-Lot for Lot
Order Policy Code A – Lot-for-Lot - “If you need 10 today and 20 tomorrow, and none are available you will get planned orders for 10 today and 20 tomorrow!!”.
Creates planned orders equal to the daily net requirement
Use this Order Policy Code where:
Setup, handling, order costs are insignificant-More Orders.
Item has high cost or spoilage – Demand/Order are 1 to 1.
Specialty items in a job shop.
End-items produced at fairly constant rate with no changes.
Require minimum projected Inventory Balance with no need for service parts. Minimal Service Level to customers.

19. Order Policy A – Lot for Lot – No Order Modifiers

20. Order Policy A - 10% Shrinkage - No modifiers

21. Order Policy A – Modifier - Minimum 400
Minimum Planned to satisfy Lot-for-Lot demand….Not planned again until required.
Minimum Planned to meet demand!
Sufficient inventory still available
Always Orders Minimum

22. Order Policy A - Multiple 12 - Minimum 400
Still Lot-for-Lot, with a Minimum Order Quantity of 400, but must make or buy in multiples of 12.

23. Policy Code D-Fixed Order Quantity
Based on EOQ (Economic order quantity) calculation. Maintained in Fixed Order Quantity Field
Similar to Minimum Order Quantity
Use when:
Demand is fairly steady
Cost is insignificant
Packaging or handling constraints might determine order size
An EOQ type of order quantity is required

24. Order Policy D - FOQ 400

25. Order Policy D Fixed Order Quantity - Multiple 12 - FOQ 400

26. Order Policy Code F-Part Period Balancing Std. Cost
MRP dynamically determines variable EOQs through time, using 2 step approach:
Uses set-up cost, order cost, carrying cost to develop order quantity (EOQ from 1960’s)
Not the JIT/lean approach
Attempts to avoid placing next order in a period of low demand
Use when demand is erratic, order/setup costs are high
Policy F is sensitive to minor schedule changes

27. Order Policy F - Order Cost $60 - Item Cost $70 - Carrying Rate 25%/yr

28. Policy Code I Part Period Balancing Current Costs
Calculates same as Policy F except that current costs are used
Search order:
Current unit cost
Last cost
Unit cost default

29. Policy Code G-Time Period of Supply
Totals all Requirements within the Days Supply
XA default Order Policy Code when adding an Item Balance/Warehouse record
Starts count of days with 1st net Requirement found
A time period = 0 or 1 equates to Policy A
Use when
Unit and carrying costs are low
Desire to set up blanket order releases
Setup and purchase costs are insignificant
Demand is erratic

30. Order Policy G – with 5 days of supply

31. Order Policy G - 5 days of supply - Multiple 12

32. Order Policy G - 10 days of supply

33. Policy Code H Order discretely above Fixed Qty
Summarizes Requirements until fixed qty is exceeded.
Placed as order on 1st day that has net requirements.
Fixed Order quantity specifies fixed qty
The planned order qty must equal or exceed the FOQ (fixed order quantity) before the order is planned
Use when vendor/mfg specifies min order qty

34. Policy Code H - Kanban
Kanban…Fixed Order Quantity and Maximum Quantity set to same number
Planned Order quantity will always be for the same quantity (i.e. quantity matches the Kanban card)
Multiple orders can be placed on the same date, if the total requirement quantity exceeds the Kanban quantity (example: one order per truck load).

35. Order Policy H – Order Above Fixed order Qty 400
Requirements of 440 over 400 at this point!

36. Order Policy H - Fixed order Qty 400 – Multiple 12

37. Order Policy Code Z Code Z –
Can use your own ordering routine in program AMM34 or code Z defaults to order policy A (discrete)
If none of the other order policy codes work for your organization you can customize your own ordering policy
MRP programs must be modified to call your program to calculate order quantity

38. Summary
There is no ‘wrong’ order policy code, each one will plan orders to cover the requirements
By using the Order Policy Codes in conjunction with Minimum, Multiple and Maximum quantity modifiers you can have MRP/AVP plan for the correct order quantity
Once Order Quantities and start/due dates are correct, begin using ‘Auto Release’ of MO’s & PO’s to maximize planner efficiency
