Group Structure RoPA

Overview

GDPR Art. 30 applies to each controller and each processor individually. In a corporate group comprising a holding company, operating subsidiaries, shared service centres, and joint ventures, each entity that independently determines purposes and means of processing must maintain its own Art. 30(1) records. Entities acting as processors for group companies must maintain Art. 30(2) records. This skill addresses the complexities of group-level RoPA management including entity hierarchy, intra-group data flows, shared processing activities, and consolidated governance.

Entity-Level vs Group-Level Records

Entity-Level RoPA (Required)

Each legal entity must maintain its own RoPA containing processing activities for which it is controller or processor. This is a legal obligation that cannot be satisfied by a group-level record alone.

Entity	Controller RoPA (Art. 30(1))	Processor RoPA (Art. 30(2))
Helix Biotech Holdings SE	Minimal — shareholder data, board member data	None
Helix Biotech Solutions GmbH	Full — all German processing activities	Yes — shared services provided to group
Helix Biotech Solutions Ltd	Full — all UK processing activities	None
Helix Biotech Solutions Inc.	Full — all US processing activities	Yes — pharmacovigilance processing for GmbH
Helix Shared Services B.V.	Minimal — own employee data only	Yes — IT, HR, and finance processing for all group entities
Helix Biotech Diagnostics S.A.S.	Full — all French processing activities	None

Group-Level Consolidated View (Recommended)

In addition to entity-level records, maintain a consolidated group view that:

1. Aggregates all entity-level RoPA entries into a single searchable register.
2. Highlights intra-group data flows and transfer arrangements.
3. Identifies shared processing activities and joint controller arrangements.
4. Supports group-level reporting to the board and supervisory authorities.
5. Enables gap analysis across entities (e.g., one entity has incomplete records).

The consolidated view is not a legal substitute for entity-level records but serves governance and oversight purposes.

Intra-Group Data Flows

Controller-to-Controller Transfers

When one group entity transfers personal data to another group entity and each determines its own purpose for the processing, this is a controller-to-controller transfer requiring:

• Legal basis: Art. 6(1) lawful basis for the disclosure (typically Art. 6(1)(f) legitimate interest with intra-group LIA)
• Transfer mechanism: If the receiving entity is outside the EEA, an appropriate Chapter V safeguard (SCCs, BCRs, adequacy decision)
• RoPA documentation: Both entities must record the transfer in their respective RoPAs — the disclosing entity as a recipient under Art. 30(1)(d), the receiving entity as data source documentation

Example:

Helix Biotech Solutions GmbH (Germany) shares employee directory data with Helix Biotech Solutions Inc. (US) for internal communications.

Aspect	GmbH (Disclosing Controller)	Inc. (Receiving Controller)
Purpose	Enable employee collaboration across group	Maintain employee directory for US operations
Lawful basis	Art. 6(1)(f) — legitimate interest (Recital 48: intra-group transfers)	Art. 6(1)(f) — legitimate interest
RoPA field	Art. 30(1)(d): Recipient = Helix Biotech Solutions Inc.; Art. 30(1)(e): US transfer	Art. 30(1)(c): Data source = Helix Biotech Solutions GmbH
Transfer mechanism	EU-US Data Privacy Framework (if Inc. is DPF-listed) OR EU SCCs Module 1 (controller-to-controller)	—
LIA reference	LIA-2024-DIR-001	LIA-2024-DIR-002

Controller-to-Processor Transfers (Intra-Group)

When a group shared service centre processes data on behalf of another group entity, the relationship is controller-to-processor even though both entities are in the same corporate group:

• Art. 28 DPA required: An intra-group DPA is required between the controller entity and the processor entity, even within the same group.
• RoPA documentation: The controller entity records the shared service centre as a processor in Art. 30(1)(d). The shared service centre records the controller entity in its Art. 30(2)(a) processor records.

Example:

Helix Shared Services B.V. (Netherlands) processes payroll for all group entities.

Controller Entity	DPA Reference	Processing Categories	Data Categories
Helix Biotech Solutions GmbH	DPA-IG-2024-SSC-DE-001	Payroll calculation, tax reporting, social security reporting	Employee names, tax IDs, bank accounts, salaries
Helix Biotech Solutions Ltd	DPA-IG-2024-SSC-UK-002	Payroll calculation, HMRC reporting, pension contributions	Employee names, NI numbers, bank accounts, salaries
Helix Biotech Solutions Inc.	DPA-IG-2024-SSC-US-003	Payroll calculation, IRS reporting, benefits administration	Employee names, SSNs, bank accounts, salaries

Joint Controller Arrangements (Art. 26)

When two or more group entities jointly determine the purposes and means of processing, they are joint controllers under Art. 26:

• Art. 26 arrangement required: Formal arrangement determining respective responsibilities.
• RoPA documentation: Each joint controller records the arrangement in Art. 30(1)(a) with cross-reference to the Art. 26 arrangement.

Example:

Helix Biotech Solutions GmbH and Helix Biotech Solutions Ltd jointly conduct multi-country clinical trials and jointly determine the trial protocol, data collection methods, and analysis purposes.

Aspect	GmbH	Ltd
Art. 26 arrangement	JCA-2024-CT-001	JCA-2024-CT-001
Responsibilities	Trial sponsor, EMA reporting, EU site management	UK site management, MHRA reporting
Contact point for data subjects	GmbH (as designated under Art. 26(1))	GmbH (as designated)
RoPA Art. 30(1)(a)	Joint controller: Helix Biotech Solutions Ltd, ref: JCA-2024-CT-001	Joint controller: Helix Biotech Solutions GmbH, ref: JCA-2024-CT-001

Binding Corporate Rules (BCRs) and Group RoPA

If the group has approved BCRs under Art. 47, the RoPA transfer fields (Art. 30(1)(e)) should reference the BCRs as the transfer mechanism for intra-group transfers:

Transfer	Mechanism	Reference
GmbH to Ltd (UK)	UK adequacy decision (28 June 2021, extended)	N/A (adequacy)
GmbH to Inc. (US)	BCR-C ref: BCR-HELIX-2024-001 (approved by BfDI as lead SA)	BCR-HELIX-2024-001
GmbH to S.A.S. (France)	Intra-EEA — no transfer mechanism required	N/A
Shared Services B.V. to Inc. (US)	BCR-P ref: BCR-HELIX-2024-002 (processor BCRs)	BCR-HELIX-2024-002

Group RoPA Governance Model

Centralised Governance with Local Execution

Role	Scope	Responsible Entity
Group DPO	Overall RoPA governance, consolidated reporting, group-level standards	Helix Biotech Holdings SE (Dr. Elena Voss)
Entity Privacy Lead	Entity-level RoPA creation and maintenance	Each subsidiary
Shared Services Privacy Lead	Processor RoPA for all shared services	Helix Shared Services B.V.
Group Privacy Analyst	Consolidated view management, cross-entity gap analysis	Holdings SE

Governance Workflow

1. Entity-level creation: Each entity's privacy lead creates and maintains entity-level RoPA entries following group standards.
2. Group template: All entities use the same RoPA template and field definitions to ensure consistency.
3. Centralised aggregation: Entity-level records are aggregated into the group consolidated view quarterly.
4. Cross-entity review: Group DPO reviews the consolidated view for intra-group transfer completeness, joint controller arrangement consistency, and entity-level gap identification.
5. Board reporting: Group DPO presents consolidated RoPA metrics to the Holdings SE board annually.

Post-Acquisition Integration

When a new entity is acquired (e.g., Helix Biotech Diagnostics S.A.S.):

1. Immediate (Day 1): Identify the acquired entity's existing RoPA and assess its format, completeness, and quality.
2. 30 days: Conduct a gap analysis against the group RoPA template and identify intra-group data flows that will be established.
3. 60 days: Migrate the acquired entity's RoPA to the group template format.
4. 90 days: Establish intra-group DPAs for shared services and document intra-group transfers in both entities' RoPAs.
5. 6 months: Full integration into the group consolidated view and ongoing governance cycle.

Common Group Structure Pitfalls

1. Assuming a single group RoPA satisfies all entities: Each legal entity must have its own records. A group-level consolidated view does not replace entity-level obligations.

2. Missing intra-group DPAs: The GDPR does not exempt intra-group processing from the Art. 28 DPA requirement. A holding company providing IT services to subsidiaries must have DPAs in place.

3. Undocumented intra-group transfers: Data flows between group entities (shared directories, consolidated HR systems, group-wide analytics) are transfers that must be recorded in Art. 30(1)(d) and (e).

4. Inconsistent entity identification: Using trade names instead of legal entity names across different entities' RoPAs creates confusion during supervisory authority inspections.

5. Missing joint controller arrangements: When two group entities jointly determine processing purposes (e.g., a global marketing campaign managed by two subsidiaries), an Art. 26 arrangement is required but frequently overlooked within corporate groups.

6. One-stop-shop confusion: The lead supervisory authority under Art. 56 is determined by the location of the main establishment, not by where most processing occurs. Group RoPA must clearly identify each entity's establishment and the lead SA for cross-border processing.
