Issue
In the classic SAP EHS system, Expert Rules (developed using Expert Rule Editor in CG02) are widely used to automate processes like classification, property value calculation, and data inheritance.
In S/4HANA Product Compliance New Functionality, there is no direct support for Expert Rules. This creates a gap for customers migrating from the classic system who depend on these automated rules.
Recommendation
Replace Classic Expert Rules with a combination of:
Business Rule Framework plus (BRF+)
Change Request Workflows
Regulatory Rule Content (via SAP Content Services)
Custom logic using BAdIs and CDS views (if required)
Background & Context
In legacy SAP EHS (CG02-based), Expert Rules were used to:
Auto-derive property values.
Copy composition data.
Apply regional compliance logic.
Expert Rule functionality is not carried forward in the new Fiori-based Product Compliance apps.
SAP now promotes rule-based checks via integrated services, supported by BRF+, predefined compliance patterns, and marketability rules.
Assumptions
Customer is migrating to or already using S/4HANA Product Compliance (New).
Composition data, DG, SVT, and Marketability checks are managed in the new compliance framework.
Business rules used in classic Expert Rules are still relevant and required post-migration.
Constraints
BRF+ and new rule mechanisms may not cover 100% of legacy Expert Rule logic.
Regulatory rule subscriptions (like SAP Content) may be required to replicate certain automated checks.
Custom logic via BAdIs might increase implementation effort and complexity.
There’s no UI-based Rule Editor as intuitive as the CG02 Expert Rule Editor.
Impacts
| Area | Impact |
|---|---|
| Automation | Need to rebuild logic using BRF+/Custom |
| Migration Effort | High if many Expert Rules exist |
| User Training | New interfaces and logic mechanisms |
| Performance | May improve with optimized BRF+ logic |
| Future-readiness | Aligns with SAP’s roadmap and innovations |
Business Rules
Examples of business rules to be rebuilt:
Copy composition from reference material
If DG classification = X, then apply specific packaging group
If substance is SVHC, then block marketability in EU
Calculate concentration sum for a regulatory group
These can be re-implemented using:
Compliance Rule Patterns
Marketability Templates
BRF+ functions
Regulatory content from SAP
