SAP indirect access: the hidden licence liability.

When third-party systems, custom applications, or automated processes read or write SAP data, licence obligations can trigger even though no named user ever logs in. This note explains how SAP prices those documents, where the exposure hides, how to measure and cap it, and how to settle it into a renewal instead of an audit demand.

Bottom line

Almost every large SAP estate carries undisclosed indirect access liability — theoretical demands run from $20M to $100M. The 2018 Digital Access model reprices the risk per document rather than per named user, but does not remove it. The winning move is to measure your own document volumes first, cap the commercial terms, and fold resolution into a renewal or S/4HANA commitment. Structured that way, comparable exposure resolves at 15–40 cents on the dollar rather than list-price back-billing.

01 Key findings

  1. The trigger is data access, not the human user. A licence obligation can arise whenever a third-party system reads or writes SAP data — a Salesforce CRM, an e-commerce catalogue, an EDI feed, a BI query, an RPA bot. The 2017 Diageo case, where SAP sought £54.6M over a Salesforce integration, put the risk on every board's radar.

  2. Digital Access repriced the risk; it did not retire it. SAP's 2018 model licenses indirect use per document across five transaction types, at roughly $0.18–$0.45 each initially. It is cheaper than the named-user alternative, but it is a new cost line, and conversion is a negotiated agreement — not automatic.

  3. Read-only and analytical access falls outside Digital Access. Document licensing covers only the five order/movement types. Master-data reads, portal navigation, and BI queries remain subject to the legacy named-user framework — the exposure most organisations miss.

  4. SAP's opening volume estimate is systematically inflated. Initial Digital Access proposals typically assume 200–400% of commercially justified volume. Independent modelling from actual measurement data produces packages 40–65% smaller — worth $3M–$12M over a five-year commitment.

  5. Measure before you answer. GLSA's pre-audit questionnaires are designed to elicit the data that quantifies your exposure. An independent assessment run first converts a reactive audit into a negotiated settlement.

02 How SAP prices documents

Under Digital Access, organisations buy a package of "documents." Each business transaction written into SAP through an indirect channel consumes one document from one of five tracked types. Benchmark pricing runs $0.18–$0.45 per document for initial purchases, falling to $0.08–$0.20 for renewals and large committed volumes.

Document typeWhat consumes itCommon indirect sourcePricing basis
Sales OrdersOrder created / written to SAPCRM, e-commerce checkoutPer document, initial $0.18–$0.45
Purchase OrdersPO written via integrationEDI, procurement platformsPer document; volume-driven
Service OrdersService record postedField-service apps, portalsPer document
Production OrdersProduction order postedMES, shop-floor systemsPer document
Materials ManagementInventory / goods movementWMS, logistics integrationsPer document, renewal $0.08–$0.20

A mid-size manufacturer processing 2 million EDI purchase orders a year at $0.25 per document faces roughly $500,000 annually — far below the named-user equivalent, but a line item that did not exist under the legacy perpetual model.

03 Where exposure hides

The costly exposure is rarely the document flows SAP can meter cleanly — it is the read-only and analytical access Digital Access never covers. Map every integration against both frameworks before assuming you are protected.

Where the money is

The read-only trap: a large enterprise of 50,000 employees may have 8,000–15,000 people touching SAP data through non-SAP interfaces with no SAP licence. At $1,500 per Professional User, that is a theoretical $12M–$22.5M for a single year — and converting only the document flows to Digital Access leaves the entire read-only population still exposed under the named-user framework.

04 Risk-assessment framework

Before any conversation with SAP, catalogue every RFC connection, BAPI call, web service, and database query touching SAP, and score each against these four factors to produce an exposure range.

Factor 01

Integration inventory

Enumerate every connection, its source system, and whether it reads, writes, or both. Most estates find this catalogue hard to produce — integrations accumulate over years and legacy documentation is incomplete.

Factor 02

Access nature

Separate document-writing flows (Digital Access candidates) from read-only and analytical access (named-user territory). The split determines which framework prices each connection.

Factor 03

Legacy vs ongoing

Historical unlicensed use is a back-billing risk; current operations are a prospective cost-normalisation exercise. They need different negotiation strategies and settle on different terms.

Factor 04

Volume modelling

Model document volumes from actual System Measurement Program data, not SAP estimates — accounting for seasonality, growth, and planned integration changes. This is where the 40–65% package reduction is won.

05 Audit defence

SAP's GLSA team uses the System Measurement Program to log every RFC, API call, and query, then reads the log for non-named-user patterns. When that engagement opens, sequence matters more than volume of correspondence.

Do this when audited
Measure first, respond second

Run an independent indirect access assessment before answering any GLSA questionnaire. Understand your own exposure fully so you negotiate from data, not from SAP's framing. See our SAP Audit Defence guide for the full response methodology.

Do this on legacy demands
Reframe as conversion, not back-billing

SAP opens at full named-user value per year of non-compliant use — $20M–$100M for large estates. Reframe resolution as incremental licence plus a Digital Access conversion that removes ongoing enforcement risk. Achievable settlements land at 15–40% of the theoretical figure.

Do this to hold leverage
Keep credible alternatives live

A genuine third-party maintenance evaluation, a parallel Oracle or Workday workstream, or a defined S/4HANA timeline all create commercial urgency SAP must resolve. Leverage evaporates once you concede the audit narrative.

06 Settling into a renewal

The cleanest resolution folds legacy exposure and ongoing compliance into a single commercial event — a renewal or, better, an S/4HANA migration — where favourable Digital Access pricing rides the larger deal.

The settle-into-renewal lever

Bundle, then protect. The S/4HANA migration is the optimal moment to negotiate a clean Digital Access framework covering all planned integrations. Insist on three protective terms: a capped overuse rate so modest volume exceedance is not penalised; a precise per-type document definition that blocks interpretive expansion by SAP's measurement tools; and an audit-exclusion clause for historical use predating conversion. Our S/4HANA Negotiation guide covers the migration commercial strategy in full.

Price your indirect access risk before SAP does

Our SAP practice quantifies exposure from your own measurement data and structures resolution into a renewal — typically at 15 to 35 cents on the dollar.
