METHOD07 - Count Method

Overview

The Count Method uses existing handling unit data from document detail lines or warehouse activities instead of calculating handling unit quantities. This method is useful when handling units have already been assigned or created in the system and you want to count them.

Purpose

This method calculates the Expected Shipment Handling Unit Qty. by:

  1. Counting handling units from document detail lines (if available)
  2. Counting handling units from warehouse activities (if available)
  3. Using different counting methods based on configuration
  4. Falling back to default calculation if no existing data is found

Parameters

Parameter Name Type Description Default
COUNT UNIQUE CARR Boolean If true, count all handling units (including duplicates); if false, count only unique handling units false
COUNT METHOD Integer Counting method: 0=Unique Handling Units (Document), 1=Unique Handling Units (Line), 2=Detail Lines (empty)
SKIP DFLT CARRIER Boolean Skip default handling unit quantity calculation if no existing data found false
SET CARRIER QUANTITY Boolean Set Handling Unit Quantity if Result = 0 (requires SKIP DFLT CARRIER = true) false

Algorithm

Step 1: Initialize Counting

Initialize the result counter and temporary handling unit tracking.

Step 2: Count from Document Detail Lines

If detail lines exist for the document line:

If COUNT METHOD = 0 (Unique Handling Units - Document level):

  • Count unique handling units that haven't appeared in previous document lines
  • For each detail line handling unit:
    • Check if handling unit already counted in previous lines
    • If not, add to count

If COUNT METHOD = 1 (Unique Handling Units - Line level):

  • Count unique handling units within the current document line only
  • Each unique handling unit number counts as 1

If COUNT METHOD = 2 (Detail Lines):

  • Count all detail lines (one handling unit per detail line)
  • Simple count of detail line records

Step 3: Count from Warehouse Activities

If warehouse activities exist for the document line:

Apply the same counting method (0, 1, or 2) as used for detail lines.

Step 4: Handle Zero Result

If result = 0 after counting:

If SKIP DFLT CARRIER = false:

  • If no detail lines AND no activities exist:
    • Calculate using METHOD06 (Simple Calculation)
    • Use this as the result

If SKIP DFLT CARRIER = true:

  • If SET CARRIER QUANTITY = true:
    • Set DocumentLine."Handling Unit Quantity" as the result
  • Else:
    • Return 0

Calculation Steps

Counting Methods Explained

Method 0: Unique Handling Units (Document)

  • Counts handling units that are unique across the entire document
  • A handling unit that appears in multiple lines is counted only once
  • Checks previous lines to avoid double-counting

Method 1: Unique Handling Units (Line)

  • Counts unique handling units within the current document line only
  • Each unique handling unit number counts as 1
  • Does not check previous lines

Method 2: Detail Lines

  • Simple count of detail line records
  • Each detail line = 1 handling unit
  • No uniqueness check

Examples

Example 1: Count Unique Handling Units (Document Level)

Scenario:

  • Document has 3 lines
  • Line 1: Handling Units A, B
  • Line 2: Handling Units B, C (B already counted)
  • Line 3: Handling Unit D
  • COUNT METHOD = 0

Calculation:

  • Line 1: Count A, B → 2 handling units
  • Line 2: Count C only (B already counted) → 1 handling unit
  • Line 3: Count D → 1 handling unit
  • Total: 2 + 1 + 1 = 4 unique handling units

Result: 4 handling units

Example 2: Count Unique Handling Units (Line Level)

Scenario:

  • Document line has detail lines with handling units: A, B, B, C
  • COUNT METHOD = 1

Calculation:

  • Unique handling units in line: A, B, C
  • Count: 3 handling units

Result: 3 handling units

Example 3: Count All Detail Lines

Scenario:

  • Document line has 5 detail lines
  • COUNT METHOD = 2

Calculation:

  • Count all detail lines: 5 handling units

Result: 5 handling units

Example 4: Fallback to Default Calculation

Scenario:

  • No detail lines exist
  • No warehouse activities exist
  • SKIP DFLT CARRIER = false
  • Quantity = 100 pieces
  • CarrierTypeUOM."Qty. per UOM Code" = 50 pieces per handling unit

Calculation:

  • No existing data found
  • Fallback to METHOD06 calculation: 100 / 50 = 2 handling units

Result: 2 handling units

Example 5: Use Handling Unit Quantity Field

Scenario:

  • No detail lines exist
  • SKIP DFLT CARRIER = true
  • SET CARRIER QUANTITY = true
  • DocumentLine."Handling Unit Quantity" = 3

Calculation:

  • No existing data found
  • Use handling unit quantity field: 3 handling units

Result: 3 handling units

Important Notes

  • This method relies on existing handling unit data in the system
  • If no data exists, it can fall back to calculation or use the handling unit quantity field
  • The counting method determines how handling units are counted (unique vs. all)
  • Handling Unit Stack ID is considered when checking for uniqueness
  • Warehouse activities are checked in addition to detail lines
