What is Segregation of Duties in SAP?
Segregation of Duties (SoD) is the principle that no single person should be able to complete an end-to-end business transaction entirely on their own — particularly when that transaction involves financial data. The logic is simple: if the same employee can both initiate and approve a payment, create a vendor and process invoices for that vendor, or post a journal entry and reconcile the account, they have the means and opportunity to commit fraud with no automatic check in the system.
In SAP, SoD conflicts arise when a user's combined role and profile assignments grant access to functions that should be separated. The conflict is not about what the user actually does — it's about what they could do with the access they hold. A user who has never committed fraud but holds conflicting access is still an SoD violation, because the control depends on access segregation, not behavioral observation.
This distinction matters for auditors. SOX ITGC controls require that SoD conflicts are identified and either remediated (the conflicting access is removed) or mitigated with compensating controls. The existence of an unmitigated SoD conflict — even if no fraud has occurred — is a control failure.
The highest-risk SoD conflicts in SAP
SoD conflicts are organized by business process area. The most critical are those that enable financial fraud in financial accounting, procurement, and human resources:
Create Vendor Invoice + Approve Payment Run
A user who can post vendor invoices (FB60) AND execute payment runs (F110) can create fraudulent invoices for shell vendors and process the payment — a complete accounts payable fraud cycle with no second pair of eyes required.
Create Purchase Order + Approve Purchase Order
A user who can create purchase orders (ME21N) AND approve their own purchase orders bypasses the dual-control requirement for procurement. They can order goods or services from any vendor for any amount without a second approver — enabling kickback schemes and fraudulent procurement.
Maintain HR Master Data + Process Payroll
A user who can modify HR master records (employee bank accounts, salary rates) AND process payroll can redirect payments to themselves or fictitious employees. This is the classic payroll fraud SoD conflict and appears in almost every SoD ruleset.
Create Purchase Order + Post Goods Receipt
A user who can create a PO and confirm goods receipt can falsify receipt of goods that were never delivered — enabling payment for non-existent deliveries. Requires a third party (AP) to complete the fraud cycle but reduces the number of colluding parties needed.
Create Customer Master + Post Customer Payments
A user who can create customer records and apply customer payments can create fictitious customer credits, redirect genuine customer payments to incorrect accounts, or manipulate accounts receivable aging.
Post Journal Entries + Approve Journal Entries
A user with both posting and approval authority for general ledger journal entries can manipulate financial statements by creating and self-approving fictitious accounting entries.
How SoD analysis works technically in SAP
A complete SoD analysis cannot be done by looking at role names alone. The actual conflict is at the authorization object level — specifically, whether a user's combined authorizations allow them to perform both sides of a conflicting function pair.
For example, the Purchase Order Create vs. Approve conflict requires checking whether the user holds authorization object M_BEST_BSA (purchase order document type authorization) with ACTVT=01 (create) AND the approval authorization at the same organizational level (purchasing organization, purchasing group). A user with create authority in one purchasing organization and approve authority in a completely different purchasing organization may not represent a genuine SoD risk.
This is why SoD rulesets are complex and why organizations with large role landscapes can have hundreds or thousands of SoD conflicts when analysis first runs — many of which are technical conflicts that don't represent genuine business risk given the organizational level restrictions.
Total violations found: 47 Critical: 12 | High: 23 | Medium: 12
CRITICAL — SOD-FI-001 User: AP_LEAD_01 Function 1: Create Vendor Invoice (Z_FI_ACCOUNTS_PAYABLE) Function 2: Approve Payment Run (Z_FI_PAYMENT_RUN) Conflicting roles: Z_FI_ACCOUNTS_PAYABLE, Z_FI_PAYMENT_RUN Risk: Full AP fraud cycle possible without second approver Recommendation: Remove Z_FI_PAYMENT_RUN from AP_LEAD_01 or implement compensating control: payment run log review
CRITICAL — SOD-MM-001 User: PROC_MGR_03 Function 1: Create Purchase Order (Z_MM_PURCHASER) Function 2: Approve Purchase Order (Z_MM_PURCHASE_APPROVE) Risk: Self-approval of purchase orders — dual control bypassed Recommendation: Remove approval role or restrict approval to orders created by others (workflow configuration)
Remediating SoD conflicts: the three options
When an SoD conflict is identified, there are three legitimate responses. The choice depends on the business requirement, the user's role, and the control environment.
Option 1 — Role separation (preferred): Remove one of the conflicting functions from the user's access. If an AP clerk doesn't need to run payment runs, remove that access. This is the cleanest resolution — the conflict no longer exists. In SAP, this means modifying the role assignment in SU01 or the composite role in PFCG.
Option 2 — Compensating controls: Where role separation is not operationally feasible (small teams, senior roles that genuinely need broad access), a compensating control provides an equivalent level of assurance. Common compensating controls include management review of payment runs before release, independent reconciliation of vendor master changes, periodic SoD conflict reporting reviewed by a second party, and enhanced monitoring of transactions executed by the conflicted user.
Option 3 — Risk acceptance: For low-risk conflicts where the business impact is genuinely minimal, formal risk acceptance by the process owner and documentation in the risk register is the appropriate response. This is the least preferred option for Critical conflicts — auditors will scrutinize risk acceptance decisions on high-value financial transactions.
SoD rulesets: what they contain and how to build one
An SoD ruleset is the complete library of conflict definitions your organization uses for analysis. SAP GRC ships with a standard Global Rule Set that covers most common ERP conflict scenarios. Organizations customize it to reflect their specific business processes, industry requirements, and risk tolerance.
A well-structured SAP SoD ruleset defines conflicts at the function level (business capability) rather than just the transaction level. A "function" is a group of related SAP capabilities — "Vendor Invoice Posting" includes FB60, MIRO, FB65, and the relevant document types and posting keys. Organizing rules at the function level makes the ruleset more maintainable and ensures that alternative transaction paths to the same capability are captured.
| Conflict | Function A | Function B | Key T-codes | Risk |
|---|---|---|---|---|
| SOD-FI-001 | Vendor Invoice Create | Payment Run Execute | FB60, MIRO / F110 | CRITICAL |
| SOD-MM-001 | PO Create | PO Approve | ME21N / ME28 | CRITICAL |
| SOD-HR-001 | HR Master Maintain | Payroll Execute | PA30 / PC00_M99 | CRITICAL |
| SOD-FI-002 | Customer Master Create | Payment Posting | FD01 / F-28 | HIGH |
| SOD-MM-002 | PO Create | Goods Receipt | ME21N / MIGO | HIGH |
| SOD-SD-001 | Sales Order Create | Customer Credit Approve | VA01 / FD32 | HIGH |
How SyntaAI runs SoD analysis
SyntaAI's run_sod_check tool connects to your SAP system via RFC, reads user-to-role assignments from AGR_USERS, role-to-transaction mappings from AGR_TCODES, and authorization object values from AGR_1251. It evaluates every active user against the SoD conflict library — checking whether the combination of roles creates access to both functions in a defined conflict pair.
The analysis runs across all connected SAP systems simultaneously. A user in an ECC system may have conflicting access across multiple systems that individually look clean — SyntaAI's cross-system view catches conflicts that single-system analysis misses.
Results are delivered as a structured report: total violations by severity, top-risk users, specific conflicting role combinations, and recommended remediation for each finding. The AI layer adds business context — explaining in plain English what each conflict means in terms of fraud risk, not just which authorization objects are involved.

What is Segregation of Duties in SAP?
The principle that no single person should be able to complete an end-to-end business transaction alone — especially one involving financial data. In SAP, an SoD conflict arises when a user's combined role and profile assignments grant access to functions that should be separated.
What is an example of an SoD conflict?
A user who can both initiate and approve a payment, both create a vendor and process invoices for that vendor, or both post a journal entry and reconcile the account. Each gives one person the means and opportunity to commit fraud with no automatic check.
Is it a violation if the user never misused the access?
Yes. The control depends on access segregation, not behavioral observation — a user who has never committed fraud but holds conflicting access is still an SoD violation, because the risk is the capability. This distinction matters to auditors.
How are SoD conflicts detected?
By comparing each user's combined role and profile assignments against a ruleset of conflicting function pairs, resolving access down to the underlying authorizations, and reporting violations by severity. AI adds prioritization so you see which conflicts represent real risk.
How do you remediate an SoD conflict?
Either remediate it — remove one side of the conflicting access — or, where the access is genuinely needed, mitigate it with a documented compensating control. SOX ITGC requires conflicts to be identified and then either remediated or mitigated with evidence.
