Before connecting an AI agent to SAP, test an operation its deployment identity is not allowed to perform. Send the request through the actual agent-to-SAP route, confirm SAP’s authorization enforcement point rejects it, verify protected data or state remains unchanged, and check that the denial is logged against the right identity and action. Then repeat the same request with an authorized test identity as a control. A prompt-level refusal alone does not prove SAP will block an unauthorized call.
What a successful denied-path test proves
A useful test establishes that the request reached the system responsible for enforcing authorization and was rejected there—not merely that the agent declined to answer or that a connection failed. SAP’s Joule Agents Compliance Brief describes Joule agents acting for a human as bound to a subset of that user’s permissions. That product-specific description should not be assumed to apply to every custom agent, adapter, or third-party integration. SAP also says agent behavior is shaped by prompts, context, and tool definitions, which is why prompt wording is not a substitute for backend authorization. See SAP’s Joule Agents Compliance Brief, version 1.0, dated June 17, 2026 and SAP’s Joule agent best practices.

The test is strongest when it pairs a denied identity with an authorized control identity, both attempting the same narrow operation. If the denied request never reaches SAP, the result is inconclusive: a missing destination, failed authentication, routing problem, or broken tool can look like a denial. SAP documents a Joule skill case where direct testing worked but the API was not reached when invoked through an agent; destination, authentication, or authorization configuration were typical causes. See SAP support note 3529717.
How to run the test
1. Choose one operation with a clear permission boundary
Select a specific read or write operation and resource. For a read, choose a record or field the test identity should not be able to see. For a write, use a low-risk, reversible change in a non-production environment. Agree with the SAP system owner on the expected authorization object, role, scope, or service-level policy. Avoid broad data extraction and production writes.

2. Prepare two test identities
Use one identity that lacks the selected permission and one that has it. Exercise the identity and delegation route intended for deployment. If the agent is expected to act on a user’s behalf, verify which identity and permission scope actually arrive at the SAP-facing service; the chat interface does not establish this. SAP’s Joule brief describes provisioned agent identity and a recorded delegation chain for delegated actions, but those details are not a guarantee for other integrations.
3. Capture the baseline and configuration
Record the identities’ relevant roles or scopes, target resource, requested operation, agent and tool versions or configuration, connection or destination, and relevant resource state. Use synthetic or otherwise approved test data. These details help distinguish an authorization decision from a setup failure and make later runs comparable.
4. Send the request through the deployed route
Ask the agent to invoke the real tool using the lower-privilege identity. Do not rely on a direct backend test or a natural-language refusal. Confirm that the request is visible at the tool gateway or SAP-facing enforcement point and can be correlated with the test identity and operation. If no request arrives, investigate authentication, destination, routing, and tool configuration; do not mark the security test as passed.

5. Verify response, state, and evidence
- Response: The tool or service reports an authorization rejection, and the agent does not claim it completed the operation or invent a result.
- State or data: The protected read is not returned, or the attempted write has not changed the resource. Compare with the captured baseline.
- Evidence: Logs identify the principal or delegation context, attempted action, target, timestamp or correlation identifier, and denial outcome.
SAP AI Launchpad documentation lists failed scope checks and failed resource-group authorization checks as security events. SAP’s Joule brief describes audit information including agent identity, permission set, action, and delegation chain. Event schemas and availability depend on the product and integration; see SAP AI Launchpad security events.
6. Run the authorized control and record the result
Repeat the identical operation with the identity that has the required permission. It should succeed only as intended, and its success event should be distinguishable from the denial. Re-run the checks after material changes to role mappings, tools, prompts, models, destinations, or deployment configuration. Record the configuration for each run because results can vary with model and configuration.
Test cases to include
| Case | Principal and request | Expected outcome | Evidence to retain |
|---|---|---|---|
| Denied read | Identity without read scope asks the agent to retrieve a selected resource through the real tool route. | Backend authorization denial; no protected data returned. | Request reached enforcement point; denial and identity correlate in logs. |
| Denied write | Identity without write scope asks for a controlled, reversible change in a test environment. | Backend authorization denial; resource remains unchanged. | Denial event and before-and-after state. |
| Allowed control | Authorized identity repeats the same operation. | Operation succeeds only within the granted permission. | Success event correlated to the authorized principal. |
| Broken-path control | In a non-production test, invoke the tool with an intentionally invalid destination or unavailable tool. | Connection or invocation failure—not an authorization pass. | Evidence that the request did not reach the enforcement point. |
| Injection-resilience check | Least-privilege identity supplies untrusted content instructing the agent to attempt the protected operation. | Backend still denies; the policy boundary is not bypassed. | Injection-test result, tool invocation, and backend audit evidence. |
This is a practical test structure, not a SAP certification procedure. SAP’s developer tutorial describes generated checks for content safety, prompt-injection resistance, per-MCP-server tool correctness, and end-to-end flows. Those checks complement—but do not replace—explicit assertions for authorization rejection, unchanged state, and log evidence. See SAP’s agent evaluation tutorial.

- The agent refuses, but no backend request is recorded: The run shows a refusal, not that SAP would reject a tool call under a different prompt or input. Test the actual tool route.
- The call fails before reaching SAP: Diagnose connection, authentication, destination, routing, or invocation. This is not proof of an authorization denial.
- SAP denies the action, but logs lack identity or action details: The enforcement may be working, but the evidence is insufficient for reliable audit or incident review. Improve observability and repeat the test.
- The agent has more tools than its task requires: Reduce its exposed toolset, then retest. SAP’s Joule Studio classic-edition guidance says to grant access only to tools essential for the agent’s job. Tool minimization reduces the action surface; it does not replace backend authorization.
- Prompt-injection checks pass: Keep them, but do not treat them as proof of authorization. Test the denial and resulting state directly.
What to verify about the integration
Before relying on any architecture, establish which principal reaches the authorization check, where the rejection occurs, what tools the agent can call, and whether denied actions can be correlated in logs. Also determine how sensitive actions are reviewed or reversed and whether authorization checks are tested separately from prompt-injection, tool-correctness, and end-to-end flows. Product behavior and logging vary by version and integration. In particular, using an SAP-related adapter does not by itself establish governance, authorization, or audit controls: SAP CAP’s MCP documentation notes that the adapter alone does not provide automatic governance controls.
