How Free Goods Determination Works in Sales Orders

What is Free Goods Determination in SAP SD?

Free goods determination in SAP Sales and Distribution (SD) allows companies to offer additional products at no extra charge based on specific rules or promotional offers. This functionality enhances customer satisfaction and boosts sales volume by providing incentives such as “Buy 3, get 1 free.”

Inclusive vs Exclusive Free Goods Explained

Inclusive Free Goods: The free items are part of the original order quantity. For example, if a customer orders 10 and qualifies for 3 free items, they pay for only 7.
Exclusive Free Goods: The free goods are added in addition to the ordered quantity. If 10 are ordered and 3 are free, the customer receives 13 items but pays for 10.

Limitations of Free Goods in SAP Sales Orders

1:1 Ratio Requirement for Free Goods

SAP currently only supports a 1:1 mapping for free goods. This means:

One sales order item can lead to one free goods item.
Complex multi-item conditions like “Buy Product A and B to get Product C free” are not supported.

Restrictions with Material Structures (BOM, Variants)

Free goods do not function with material structures like:

Bills of Materials (BOMs)
Product selection
Variant configurations with BOM explosions

Limitations by Document Category (Only Category 'C')

Only sales order documents with category ‘C’ are eligible for free goods. Other types like quotations are excluded. Use transaction VOV8 to check or modify document categories.

Exclusion from Non-Sales-Order Deliveries

Deliveries that aren’t tied to a sales order cannot use free goods functionality. Always create orders with valid document references.

Incompatibility with Make-to-Order and Third-Party Processing

Free goods are not supported in:

Make-to-order production scenarios
Third-party processing
Scheduling agreements

Retail Specific Limitation with Generic Articles

In SAP Retail, free goods for variant articles must be processed individually. The matrix-based entry is not supported.

Understanding Document Category 'C' in SD

Free goods only work with SD document category ‘C’ (Sales Order). To verify:

1. Go to transaction VOV8
2. Check the document category assigned to your order type
3. Ensure it's correctly mapped to allow free goods processing

Pre-Configuration Checks for Free Goods Setup

Before setting up free goods:

Ensure your SAP version supports this function (e.g., SAP 4.6x+)
Validate number range configuration using WC07
Review common setup issues like missing pricing procedures or wrong assignment

Step-by-Step: How to Configure Inclusive Free Goods

Let’s configure a scenario where:

Minimum order quantity: 5
For every 3 items, 1 is free

Step 1: Maintain Number Range Intervals (WC07)

No	From Number	To Number
01	0000010000	0000099999

Step 2: Maintain Access Sequences

Transaction: IMG → Sales and Distribution → Basic Functions → Free Goods → Maintain Access Sequences
Example: Create NA00 and save

Step 3: Define Condition Types

Code: FREE
Description: Free Goods
Access Sequence: NA00

Step 4: Maintain Pricing Procedures

Procedure Code: FREE
Go to Control Data:

Step: 10
Counter: 10
Condition Type: FREE

Step 5: Activate Free Goods Determination (V/N6)

Assign:

Order Type: OR
Document Procedure: A
Procedure: FREE

Step 6: Create Free Goods Master Record (VBN1)

Material	Min Qty	From	Free Qty	Calc Rule	Type
ABC123	5	3	1	1	Inclusive

Inclusive Free Goods Example in SAP

If a customer orders 10 units of material:

7 units are billed
3 units are free
Calculation: (10 / 3 = 3 free goods), customer pays for 10 - 3 = 7

SAP automatically determines this during order creation based on the setup above.

Common Use Cases for Free Goods Determination

Promotions: Boost sales by offering time-limited free goods
Loyalty Programs: Reward high-value customers with free products
Clearance Sales: Move slow-moving inventory without discounting price

Troubleshooting Free Goods Configuration

Common Errors:

Incorrect document category
Incomplete pricing procedures
Missing access sequences

Testing Tips:

Always simulate orders with expected volumes
Check pricing analysis to validate how free goods are applied

Best Practices for Managing Free Goods in SAP

Keep access sequences and condition types clean
Regularly review document category mappings
Audit promotional logic to avoid misuse or misconfiguration
