As organizations manage increasingly complex product substitution networks, ensuring the quality and consistency of Product Interchangeability master data becomes critical. Incorrect or incomplete master data can lead to planning inaccuracies, fulfilment challenges, and unexpected substitution behaviour.

To help organizations maintain high-quality master data while adapting to unique business requirements, Product Interchangeability introduces Configurable Validations.

This capability provides the flexibility to tailor consistency checks according to specific business requirements.

Why Configurable Validations?

Every organization follows different governance practices.

For example:

• Some organizations require strict control over product assignment in substitutions
• Certain validations may be mandatory for planning scenarios but optional for aATP processes.

Configurable Validations allow organizations to determine which business rules should be enforced and how validation results should be treated during master data maintenance.

Starting with the SAP S/4HANA 2025 FPS02 release, seven standard validations are available for configuration

Available Validation Rules for Configuration

S_V1: A product can belong to only one supersession chain

Example: A Product can belong only to one collection, maintenance across collection is not allowed as per the validation rule.

S_V2: Product-Location Combination Can Belong to Only One Supersession Chain

Example: A Product location combination cannot repeat across collection

S_V3: Atomic Substitution Must Belong to One Supersession Chain Collection

Example: Each substitution relationship must be unique across the system

S_V4: Location-Specific Atomic Substitution Must Belong to One Collection

Example: The same substitution and location combination cannot exist in multiple collections

S_V5: The product and substitute must have the same unit of measure

Example: Both products participating in a substitution must use the same base unit of measure

S_V6: The leading product must be the same across all subsets in a collection

Example: The same lead product must be maintained across all subsets within a Form-Fit-Function (FFF) collection

S_V7: Group Assignment Is Not Allowed

This validation prevents group assignments to collections.

Note: S_V7 cannot be configured for aATP because Group Assignment is mandatory for aATP relevant collections

Validation Configuration

For each consuming application, users can configure message severity. The configuration is available at: IMG Path: IMG/Cross-Application Components/ Advanced Available-to-Promise (aATP)/Product Interchangeability/Configure Consistency Checks/Maintain Validations for applications

Message Severity Options

Note: Not maintaining an entry for the validations in any of the consuming applications, does not trigger the validation

Conclusion

Configurable validations enable organizations to enforce data quality standards tailored to individual application requirements while maintaining flexibility across business processes.
