Introduction
Purpose
This document defines the Business Rules framework governing the design, implementation and operation of business processes and systems within the Syensqo transformation program.
The Business Rules provide a structured and consistent approach to:
- Ensuring alignment with the Syensqo operating model
- Enforcing standardization across business units
- Supporting consistent system behavior across SAP and integrated platforms
- Enabling strong governance, traceability, and auditability
These rules form a foundational reference for all process design, system configuration, and integration decisions across the program.
Objectives
The objectives of the Business Rules are to:
- Establish a single, consistent set of governing principles across all process domains
- Ensure alignment with Syensqo’s strategic, operational and digital objectives
- Enable standardized and scalable SAP S/4HANA implementation
- Minimize customization and process variation
- Ensure compliance with regulatory, financial, and operational controls
- Provide clear guidance for design, build, and change activities
- Support long-term maintainability and simplification of the solution landscape
Assumptions
The following assumptions apply to the definition and application of these business rules:
- SAP S/4HANA is the core enterprise system of record
- End-to-end processes are defined and governed centrally
- Business rules apply to all in-scope entities and business units
- Data ownership and accountability are clearly defined
- Standard SAP functionality is preferred over custom development
- Governance bodies (Design Authority, Process Owners) are in place and operational
- Business processes are aligned with the Syensqo Operating Model
Constraints
The following constraints apply to the implementation of business rules:
- Regulatory, legal, and statutory requirements may impose mandatory deviations
- Local legal or tax requirements may require controlled exceptions
- Legacy system dependencies may temporarily constrain full alignment
- Organizational readiness and data maturity may influence implementation sequencing
- Budget and timeline constraints may impact prioritization
All constraints must be documented and formally approved where deviations occur.
Business Rules Definition
Business Rules Overview
Business Rules define what must be adhered to when designing, implementing, and operating business processes and systems.
They apply across:
- Business process design
- SAP configuration and extensions
- Data creation and management
- Reporting and analytics
- Integration and security
Business Rules are grouped into the following categories:
- Functional Rules
- System Design Rules
- Data and Reporting Rules
- Security and Integration Rules
These rules are mandatory unless formally exempted through governance.
Business Rule Nomenclature & Identification Standard
Each Business Rule must be assigned a unique identifier using the following format:
| Element | Description | Example |
|---|---|---|
| POD | End-to-End Process Area | S2P, A2D, R2R |
| R | Denotes a Business Rule | Fixed |
| Sequential Number | Unique, zero-padded identifier | 001, 002 |
Example: S2P-R001
Naming Rules
- Rule IDs must be unique and never reused
- Rule numbering must be sequential within each POD
- Rule IDs must remain unchanged once approved
- Retired rules remain visible for audit purposes
- Rule titles must be:
- Clear
- Business-readable
Design Principles and Guidelines
The following principles guide the creation and application of all business rules.
General:
- All rules must support a standardized, enterprise-wide solution
- Rules must be based on business need and value
- Rules must be applicable across all in-scope entities
- Process definitions in the approved process repository are the single source of truth
- Local workarounds and parallel solutions are not permitted
- All changes must follow approved governance and change control
Data:
- Data must be created and maintained at the point of origin
- Manual data creation or adjustment must be controlled and approved
- Data must not be altered after posting, except under approved scenarios
- Data ownership and accountability must be clearly defined
- Data quality and integrity must be enforced through controls
Solutions:
- Multiple versions of the same process are not permitted
- Language support is standardized, with limited approved exceptions
- Custom development is allowed only where standard functionality cannot meet requirements
- Solutions must support scalability and future business growth
Process:
- Processes must be simple, standard and mandatory
- There must be one approved way to execute each process
- Processes must align with the Group Operating Model
- Processes must be business-driven, not system-driven
- Local variations are permitted only for legal or regulatory reasons
- All deviations must be formally approved
Reporting:
- A single source of truth must be maintained
- Data must not be manipulated outside SAP
- Reports must avoid hard-coded logic
- Reporting must minimize manual intervention
User Interface:
- SAP Fiori Launchpad is the standard user entry point
- User experience must be consistent across devices
- Navigation must align with approved process design
- Access must be role-based and controlled
Development:
- SAP standard functionality must be used wherever possible
- Core SAP code must not be modified
- Enhancements must follow approved extensibility principles
- Custom development requires justification and approval
Security:
- Access must be role-based and aligned with organizational structure
- Segregation of Duties must be enforced
- Authorizations must support audit and compliance requirements
- Access changes must follow formal approval workflows
Integration:
- Business process requirements drive integration design
- Each interface must have a defined system of record
- Standard SAP integration technologies must be used
- Data must be encrypted and securely transmitted
- Interfaces must prevent duplication and ensure data consistency
- Business logic must not reside in middleware
- Time zones must follow ISO standards
- Error handling must be standardized
Simplification:
- Eliminate unnecessary process variants
- Reduce custom developments
- Avoid duplication of functionality
- Promote reuse of standard solutions
- Design for long-term maintainability
Functional Rules
The functional rules will include Enterprise Structure, High Level functional configuration principles and specific functional rules. The intended audience for Functional Rules includes Business Process Leads, Process Specialists and Functional Consultants.
The Functional Rules are captured under the E2E Process Areas as below
- Idea to Market (I2M)
- Lead to Cash (L2C)
- Source to Pay (S2P)
- Plan to Fulfill (P2F)
- Acquire to Decommission (A2D) Rules
- Record to Report (R2R)
- Budget to Forecast (B2F) Rules
- Safety to Sustainability (S2S)
