The myDATA Obligation

Since 2021, all legal entities operating in Greece are required to submit their accounting records electronically to the Greek Independent Authority for Public Revenue (AADE) via the myDATA platform. This includes invoices, credit notes, retail receipts, expenses and payroll-related documents.

For organisations running SAP, manual submission is not a practical option at scale. Every document created in SAP FI or SD that falls within scope must be transmitted to AADE in real time or within defined deadlines, with a digital mark (ΜΑΡΚ) returned from AADE and stored against the SAP document.

Non-compliance carries financial penalties and increases audit risk.

The Solution: SAP eBooks for myDATA

SXC Group implements myDATA compliance using SAP’s standard eBooks solution. This is not a custom-built tool: it is SAP’s established solution for connecting SAP FI/SD document flows with AADE myDATA, supported by the standard SAP product lifecycle.

Our team has extensive experience implementing and supporting SAP eBooks in complex SAP landscapes. We configure the standard solution around each organisation’s company structure, document flows and compliance requirements while keeping custom development to a minimum.

What SXC Group Delivers

myDATA Scope Analysis

Not all documents are treated equally under myDATA. SXC Group performs a full scoping exercise across your SAP landscape to identify:

  • Which document types are in scope (outgoing invoices, intra-company, retail, expenses)
  • Which SAP company codes, sales organisations and plants are affected
  • Classification of income/expense categories (MyDATA income/expense classification codes)
  • Timing requirements for each document type

SAP eBooks Configuration and Integration

SXC Group configures and integrates the standard SAP eBooks solution to support:

  • Real-time transmission: documents submitted to AADE at the point of SAP posting
  • ΜΑΡΚ storage: AADE’s digital mark written back to the SAP document as a reference
  • UID (Unique Invoice Identity): managed where applicable for B2B invoices
  • Error handling and resubmission: failed transmissions flagged for review and retry without data loss
  • Cancellation and correction: transmission of SAP reversal and credit note documents in accordance with myDATA rules

Standard Monitoring and Compliance Controls

SXC Group configures the monitoring and compliance capabilities provided by the SAP eBooks solution to track:

  • Transmission status per document
  • AADE rejection codes and resolution guidance
  • Submission volume and compliance rate reporting
  • Outstanding documents requiring resubmission

Existing System Integration (Non-SAP Documents)

Where documents originate outside SAP, such as e-commerce, billing or legacy applications, SXC Group can assess complementary integration options. These extensions are scoped separately from the standard SAP eBooks implementation.

Support and Regulatory Updates

The myDATA specification continues to evolve as AADE extends coverage and adjusts classification rules. SXC Group provides ongoing support to keep your integration current with regulatory changes.
