SAP Validation

Why SAP requires specific validation

SAP is one of the most complex computerized systems a regulated organization can implement.

Unlike a single-purpose application, SAP is a configurable platform with:

• Thousands of customizing parameters and tables
• Customer-specific Z custom developments
• Interfaces with other systems
• A constant cycle of updates and support packages

This complexity has a direct consequence for regulatory compliance.

SAP as a commercial product can be classified as GAMP Category 4, but each customer's specific configuration, custom developments, and integrations are the user's own responsibility and require independent validation.

What regulatory agencies expect

Regulatory agencies are clear on this.

The FDA, EMA, and AEMPS expect that any computerized system supporting GxP processes is validated with documented evidence that it functions according to its intended use.

That includes processes such as:

• Batch management and quality control
• Material traceability
• Electronic manufacturing records
• Personnel training management

When that system is SAP, validation cannot be generic.

It must cover the active modules, the configured business processes, and the implemented data integrity controls.

The risk of continuous changes

SAP introduces challenges that other systems do not have.

The following changes can alter the behavior of validated processes:

• Transports between environments (DEV → QAS → PRD)
• Customizing changes
• Upgrades to new versions
• Application of Support Packages

Without a validated state management methodology adapted to SAP, each change becomes a regulatory risk.

Our approach: GAMP 5 and CSA applied to SAP

Our methodology adapts the GAMP 5 Second Edition framework and the FDA's Computer Software Assurance (CSA) guidance to the particularities of SAP.

The level of validation rigor is proportional to the risk to product quality and patient safety.

We eliminate bureaucratic documentation without regulatory value and focus on evidence that will withstand a real inspection.

Classification and regulatory impact analysis

The first step is to determine which SAP modules active in the organization support GxP processes.

Not all modules or transactions have the same regulatory impact.

We perform an impact analysis that defines the scope of validation and justifies what is included and what is excluded, with the corresponding regulatory traceability.

Complete lifecycle documentation

We cover the complete documentation cycle:

• Module-specific URS capturing GxP user requirements for each SAP module
• Functional specifications translating those requirements into SAP configuration
• FMEA risk analysis of critical transactions and processes
• Qualification protocols (DQ, IQ, OQ, PQ) adapted to the SAP context — from system configuration verification to end-to-end process testing

Validated state management

Validation does not end with the signing of the final report.

We implement a validated state management system that integrates the SAP change control process with the organization's GxP change management system.

SAP change control covers transports, SAP notes, and customizing changes.

This way, every change goes through a regulatory impact assessment before reaching production.

SAP modules we validate

SAP QM — Quality Management

The QM module is the heart of regulated processes in SAP for the pharmaceutical and medical device industries.

We validate:

• Incoming, in-process, and outgoing inspection flows
• Control batch management and certificates of analysis (CoA)
• Inspection plans and sampling methods
• Management of analysis results and their link to batch release
• Usage decisions that determine whether a material can be used in production

SAP PM — Plant Maintenance

Maintenance management in regulated environments has very specific requirements.

Critical equipment must be qualified, and periodic maintenance and calibration must be documented.

We validate:

• Equipment functional structure (functional locations and equipment masters)
• Preventive maintenance and calibration plans
• Maintenance orders and their lifecycle
• Spare parts bill of materials management
• QM integration for calibration management with measurable results

SAP MM — Materials Management

Material traceability is a fundamental GxP requirement.

We validate:

• Purchasing and receiving processes that generate traceable batches
• Qualified vendor management (approved vendor list)
• Stock movements and their traceability implications
• Management of blocked and quarantined materials
• QM integration for incoming inspection

SAP PP — Production Planning

Manufacturing orders in regulated industry are critical electronic records.

We validate:

• Process order and production order configuration
• Electronic manufacturing control records (electronic batch records) generated from SAP
• Production materials management and consumption
• Component-to-finished-product traceability
• Order confirmation and closure processes with the required data integrity controls

SAP SD — Sales and Distribution

In pharmaceutical distribution, traceability from manufacturer to dispensing point is a regulatory requirement.

We validate:

• Customer order processes
• Shipment management with batch traceability
• Distribution documentation generation compliant with GDP
• Reversals and returns with batch management
• QM integration for delivery release

SAP WM / EWM — Warehouse Management

Warehouse management in regulated environments requires temperature controls, material segregation, and complete movement traceability.

We validate both SAP WM (classic Warehouse Management) and SAP EWM (Extended Warehouse Management, the native S/4HANA module):

• Location management with controlled storage conditions
• Material inbound, relocation, and outbound processes
• QM integration for automatic blocks
• Periodic inventory counts

SAP HR / HCM — Human Capital Management

Personnel qualification is a GxP requirement frequently overlooked in SAP implementations.

We validate training and qualification management modules:

• Course and training event catalog
• Attendance and training result management
• Required qualification profiles by position
• Automatic qualification expiry alerts
• Integration with SAP access control to restrict access to GxP transactions to qualified personnel

SAP PS — Project System

SAP PS is commonly used to manage the validation and qualification projects themselves within the regulated organization.

We validate:

• Project structures and validation activity templates
• Cost control of validation projects
• Status report generation for management

SAP S/4HANA — Migrations and Upgrades

The migration from SAP ERP (ECC 6.0) to SAP S/4HANA is one of the highest regulatory risk projects for a GxP organization.

It involves:

• Changes in data structure (simplification of the MM data model)
• Changes in transactions and business processes
• Possible obsolescence of Z developments and interfaces

We manage migration validation as a structured project:

• Regulatory impact analysis on GxP processes
• Differential revalidation of affected modules
• Migrated data integrity testing
• Verification that the validated state is maintained after the transition

Managing upgrades, patches, and changes

One of the most critical characteristics of SAP in regulated environments is the frequency of changes.

The following types can alter the behavior of validated processes:

• Quarterly support packages
• Corrective SAP notes
• Enhancement projects
• Customizing modifications derived from changes in business processes

Classification of the impact of each change

We implement a Regulatory Impact Assessment procedure adapted to SAP.

Each change is classified according to its impact on the validated state:

• No impact — the change does not affect validated GxP processes
• Minor impact — requires documentary review
• Major impact — requires partial or complete revalidation

This procedure integrates with the organization's change management system and the SAP transport process.

No change reaches production without having passed the corresponding regulatory assessment.

Benefits

• Reduced regulatory risk: documentation that withstands scrutiny from FDA, EMA, AEMPS, and other agency inspectors, with complete traceability from user requirements to execution evidence.
• Operational continuity: a validated state management process that allows upgrades and changes to be applied without disrupting production or compromising regulatory compliance.
• Complete traceability: all electronic records generated by SAP in GxP processes comply with ALCOA+ principles and the requirements of 21 CFR Part 11 and EU Annex 11.
• Reduced documentation effort: the CSA-first methodology eliminates bureaucratic documentation without real regulatory value and focuses effort on the evidence that matters.
• Inspection readiness: procedures, records, and evidence organized so that an inspector can verify the validated state of the system in real time.
