METHOD01 - Normative Quantity

Overview

The Normative Quantity method calculates the remaining quantity that will be picked into a partial handling unit after full handling units have been accounted for. This is the quantity that remains after dividing the total quantity by the full handling unit capacity.

Purpose

This method calculates the Expected Orderpick Qty. by:

1. Determining the number of full handling units based on capacity
2. Calculating the remaining quantity after full handling units
3. Returning the remaining quantity as the normative orderpick quantity

Parameters

This method has no configurable parameters.

Algorithm

Step 1: Validate Input

If Quantity = 0:

• Exit with result = 0
• Go to End

Go to Step 2

Step 2: Determine Handling Unit Type

Determine which handling unit type to use:

1. Use DocumentLine."Handling Unit Type Code" if available

   • Go to Step 3 if found

2. Get handling unit type from Customer Item:

   • Try CustItem."Handling Unit Type Code (Shipment)"
   • If empty, try CustItem."Handling Unit Type Code (Receipt)"
   • Go to Step 3 if found

Step 3: Get Handling Unit Type UOM

Retrieve the Handling Unit Type Unit of Measure:

• Look up CarrierTypeUOM for customer item, unit of measure, and handling unit type
• If not found, try to get from the same handling unit type group
• Must have Qty. per UOM Code set

Go to Step 4

Step 4: Calculate Full Handling Units

Calculate the number of full handling units:

NoOfFullCarriers = Quantity div CarrierTypeUOM."Qty. per UOM Code"

Where:

• div = integer division (whole number only)

Step 5: Calculate Remaining Quantity

Calculate the quantity that remains after full handling units:

RestQty = Quantity - (NoOfFullCarriers × CarrierTypeUOM."Qty. per UOM Code")

Step 6: Round and Return Result

Result = Round(RestQty, 0.001, '>')

(Rounded up to 3 decimal places)

Calculation Steps

Variable Definitions

• A = Quantity (ordered quantity)
• B = Full handling unit capacity (Qty. per UOM Code)
• C = Number of full handling units (NoOfFullCarriers)
• D = Remaining quantity (RestQty)
• E = Final result (normative orderpick quantity)

Step-by-Step Formula

1. Get quantity:

   A = Quantity
   

2. Get handling unit capacity:

   B = CarrierTypeUOM."Qty. per UOM Code"
   

3. Calculate full handling units:

   C = A div B
   

   (Integer division - whole number only)

4. Calculate remaining quantity:

   D = A - (C × B)
   

5. Round result:

   E = Round(D, 0.001, '>')
   

   (Rounded up to 3 decimal places)

Examples

Example 1: Exact Full Handling Units

Scenario:

• Quantity = 100 pieces
• CarrierTypeUOM."Qty. per UOM Code" = 50 pieces per handling unit

Calculation:

1. Quantity: A = 100 pieces
2. Handling unit capacity: B = 50 pieces per handling unit
3. Full handling units: C = 100 div 50 = 2 handling units (100 pieces)
4. Remaining quantity: D = 100 - (2 × 50) = 0 pieces
5. Result: E = Round(0, 0.001, '>') = 0 pieces

Result: 0 pieces (no partial handling unit needed)

Example 2: With Remaining Quantity

Scenario:

• Quantity = 175 pieces
• CarrierTypeUOM."Qty. per UOM Code" = 50 pieces per handling unit

Calculation:

1. Quantity: A = 175 pieces
2. Handling unit capacity: B = 50 pieces per handling unit
3. Full handling units: C = 175 div 50 = 3 handling units (150 pieces)
4. Remaining quantity: D = 175 - (3 × 50) = 25 pieces
5. Result: E = Round(25, 0.001, '>') = 25 pieces

Result: 25 pieces (this is the normative quantity for the partial handling unit)

Example 3: Small Remainder

Scenario:

• Quantity = 101 pieces
• CarrierTypeUOM."Qty. per UOM Code" = 50 pieces per handling unit

Calculation:

1. Quantity: A = 101 pieces
2. Handling unit capacity: B = 50 pieces per handling unit
3. Full handling units: C = 101 div 50 = 2 handling units (100 pieces)
4. Remaining quantity: D = 101 - (2 × 50) = 1 piece
5. Result: E = Round(1, 0.001, '>') = 1 piece

Result: 1 piece (normative quantity for partial handling unit)

Example 4: Large Quantity

Scenario:

• Quantity = 487 pieces
• CarrierTypeUOM."Qty. per UOM Code" = 60 pieces per handling unit

Calculation:

1. Quantity: A = 487 pieces
2. Handling unit capacity: B = 60 pieces per handling unit
3. Full handling units: C = 487 div 60 = 8 handling units (480 pieces)
4. Remaining quantity: D = 487 - (8 × 60) = 7 pieces
5. Result: E = Round(7, 0.001, '>') = 7 pieces

Result: 7 pieces (normative quantity for partial handling unit)

Important Notes

• This method calculates the remaining quantity, not the number of handling units
• The result represents the quantity that will be picked into a partial handling unit
• Full handling units are calculated but not returned (only the remainder is returned)
• The result is always rounded up to ensure all items are accounted for
• This quantity is used in conjunction with shipment handling unit calculations

Use Case Example

Scenario: You have an order for 175 pieces, and each full handling unit holds 50 pieces.

Shipment Handling Unit Calculation (METHOD02):

• Calculates: 3 full handling units + 1 partial handling unit = 4 handling units total

Orderpick Calculation (METHOD01):

• Calculates: 25 pieces (the quantity in the partial handling unit)

Together, these tell you:

• 4 handling units are needed for shipment
• 25 pieces need to be picked into the partial handling unit
• 150 pieces are already in full handling units (3 × 50)
