“Define idempotency and stable external reference handling in the API-backed business process” concerns the alternative task “define idempotency and stable external reference handling in the API-backed business process”, but the stated failure is that a custom API returns sensitive customer columns because all fields from the backing table were added to the API page. The required measure is to expose only the minimal approved fields and apply entitlement and permission rules.

The proposed “Expose only approved actions and enforce permissions and validation at the service boundary” tests a different control: expose only approved actions and enforce permissions and validation at the service boundary. The reported condition is that a custom API returns sensitive customer columns because all fields from the backing table were added to the API page; the more direct action is to expose only the minimal approved fields and apply entitlement and permission rules.

“Evaluate supported read scale-out patterns for appropriate read workloads without compromising consistency needs” concerns the separate step “evaluate supported read scale-out patterns for appropriate read workloads without compromising consistency needs”. The reported issue is that a custom API returns sensitive customer columns because all fields from the backing table were added to the API page, so the direct response is to expose only the minimal approved fields and apply entitlement and permission rules.

The proposed “Verify authentication and data ownership before adding any Microsoft 365 integration” tests a different control: select supported Business Central capabilities and explicit service integrations for Microsoft 365 workflows. The reported condition is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades; the more direct action is to review customization requests for unsupported base-object replacement.

“Validate client and service assumptions in the solution architecture review” supports the separate task “document how the browser client, service tier, AL extensions and managed data platform participate in operations”, not the reported problem: a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. This case instead calls for “Review customization requests for unsupported base-object replacement”.

“Include cross-tenant negative tests for connected apps” concerns the separate step “design explicit authorized integration rather than assuming Business Central tenant databases share company data”. The reported issue is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades, so the direct response is to review customization requests for unsupported base-object replacement.

“Select supported Business Central capabilities and explicit service integrations for Microsoft 365 workflows” supports the separate task “select supported Business Central capabilities and explicit service integrations for Microsoft 365 workflows”, not the reported problem: a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. This case instead calls for “design a separate AL extension that adds the required fields and logic through supported extensibility points”.

“Replace the server-specific .NET dependency with supported AL or external service integration appropriate to cloud execution” concerns the separate step “replace the server-specific .NET dependency with supported AL or external service integration appropriate to cloud execution”. The reported issue is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades, so the direct response is to design a separate AL extension that adds the required fields and logic through supported extensibility points.

The proposed “Document how the browser client, service tier, AL extensions and managed data platform participate in operations” tests a different control: document how the browser client, service tier, AL extensions and managed data platform participate in operations. The reported condition is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades; the more direct action is to design a separate AL extension that adds the required fields and logic through supported extensibility points.

“SaaS servicing does not transfer responsibility for third-party app quality” concerns the separate step “assign extension code ownership and compatibility testing to the publisher while Microsoft maintains the online platform”. The reported issue is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades, so the direct response is to design a separate AL extension that adds the required fields and logic through supported extensibility points.

“Modularity and dependency contracts reduce coupling between Business Central solutions” concerns the alternative task “separate independently maintained capabilities into versioned extension apps with explicit dependencies”, but the stated failure is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. The required measure is to design a separate AL extension that adds the required fields and logic through supported extensibility points.

“Cross-product collaboration requires defined service boundaries” supports the separate task “select supported Business Central capabilities and explicit service integrations for Microsoft 365 workflows”, not the reported problem: a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. This case instead calls for “design a separate AL extension that adds the required fields and logic through supported extensibility points”.

“The release plan distinguishes Microsoft-managed platform updates from customer-managed extension releases” concerns the alternative task “assign extension code ownership and compatibility testing to the publisher while Microsoft maintains the online platform”, but the stated failure is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. The required measure is to the customization is deployed as an app without overwriting Microsoft's application objects.

The proposed “A small module can be updated without rebuilding unrelated modules and dependency versions stay valid” tests a different control: separate independently maintained capabilities into versioned extension apps with explicit dependencies. The reported condition is that a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades; the more direct action is to the customization is deployed as an app without overwriting Microsoft's application objects.

“The extension deploys successfully to an online sandbox without a server-local .NET assembly” supports the separate task “replace the server-specific .NET dependency with supported AL or external service integration appropriate to cloud execution”, not the reported problem: a distributor assumes every customization is a direct edit of the Business Central base application and cannot plan safe upgrades. This case instead calls for “The customization is deployed as an app without overwriting Microsoft's application objects”.

The proposed “Business events decouple cross-cutting logic from one screen” tests a different control: subscribe to an appropriate published business event or design a reusable codeunit validation at the relevant process boundary. The reported condition is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting; the more direct action is to preserve error meaning and stop or compensate the transaction rather than falsely reporting success.

“Publisher-subscriber extensibility helps maintain compatibility” supports the separate task “use available integration events and a subscriber or suitable extension point”, not the reported problem: a calculation codeunit raises an error but the caller catches and hides it, then continues posting. This case instead calls for “preserve error meaning and stop or compensate the transaction rather than falsely reporting success”.

“Public AL procedure reachability is an API surface” concerns the separate step “restrict the procedure's access with appropriate AL access modifiers and resource permissions”. The reported issue is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting, so the direct response is to preserve error meaning and stop or compensate the transaction rather than falsely reporting success.

“Review transaction boundaries and remove unintended commits from reusable business logic” supports the separate task “review transaction boundaries and remove unintended commits from reusable business logic”, not the reported problem: a calculation codeunit raises an error but the caller catches and hides it, then continues posting. This case instead calls for “preserve error meaning and stop or compensate the transaction rather than falsely reporting success”.

“Restrict the procedure's access with appropriate AL access modifiers and resource permissions” concerns the separate step “restrict the procedure's access with appropriate AL access modifiers and resource permissions”. The reported issue is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting, so the direct response is to preserve error meaning and stop or compensate the transaction rather than falsely reporting success.

The proposed “Define an AL interface and implement it in separate codeunits with a supported dispatch pattern” tests a different control: define an AL interface and implement it in separate codeunits with a supported dispatch pattern. The reported condition is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting; the more direct action is to preserve error meaning and stop or compensate the transaction rather than falsely reporting success.

“Unapproved external code cannot call the protected operation while authorized modules work” concerns the alternative task “restrict the procedure's access with appropriate AL access modifiers and resource permissions”, but the stated failure is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting. The required measure is to a simulated validation failure blocks completion with a useful diagnostic.

The proposed “Repeated calls with the same inputs produce consistent values” tests a different control: refactor it to accept explicit inputs and return a well-defined result without hidden mutable dependencies. The reported condition is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting; the more direct action is to a simulated validation failure blocks completion with a useful diagnostic.

“The custom behavior runs after updates without maintaining a duplicate core codeunit” supports the separate task “use available integration events and a subscriber or suitable extension point”, not the reported problem: a calculation codeunit raises an error but the caller catches and hides it, then continues posting. This case instead calls for “A simulated validation failure blocks completion with a useful diagnostic”.

“Review deprecated or changed events during upgrades” concerns the alternative task “use available integration events and a subscriber or suitable extension point”, but the stated failure is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting. The required measure is to track suppressed exceptions in posting workflows.

“Add regression cases for alternate event paths” supports the separate task “inspect the event signature and handle missing or incomplete values according to contract”, not the reported problem: a calculation codeunit raises an error but the caller catches and hides it, then continues posting. This case instead calls for “Track suppressed exceptions in posting workflows”.

“Review access modifiers on new reusable codeunits” concerns the separate step “restrict the procedure's access with appropriate AL access modifiers and resource permissions”. The reported issue is that a calculation codeunit raises an error but the caller catches and hides it, then continues posting, so the direct response is to track suppressed exceptions in posting workflows.

The proposed “Inspect custom dimensions before production deployment” tests a different control: emit minimized non-sensitive dimensions and avoid personal data in custom signals. The reported condition is that an AL process emits high-volume debug telemetry on every table row and overloads ingestion; the more direct action is to track custom-event rates after major feature releases.

“Check destination configuration before release” supports the separate task “configure a supported telemetry destination and confirm the extension's emitted events reach it”, not the reported problem: an AL process emits high-volume debug telemetry on every table row and overloads ingestion. This case instead calls for “Track custom-event rates after major feature releases”.

“Validate dashboard queries when event schemas change” concerns the separate step “use stable event identifiers and a controlled schema for emitted telemetry”. The reported issue is that an AL process emits high-volume debug telemetry on every table row and overloads ingestion, so the direct response is to track custom-event rates after major feature releases.

“Correlation reduces ambiguity in distributed troubleshooting” concerns the separate step “use supported telemetry correlation identifiers and span context where available”. The reported issue is that an AL process emits high-volume debug telemetry on every table row and overloads ingestion, so the direct response is to use appropriate verbosity and targeted instrumentation for meaningful events.

“Performance telemetry needs meaningful operation-level segmentation” concerns the alternative task “measure report-specific duration and relevant operation dimensions over comparable periods”, but the stated failure is that an AL process emits high-volume debug telemetry on every table row and overloads ingestion. The required measure is to use appropriate verbosity and targeted instrumentation for meaningful events.

The proposed “Telemetry generation and telemetry collection are separate setup steps” tests a different control: configure a supported telemetry destination and confirm the extension's emitted events reach it. The reported condition is that an AL process emits high-volume debug telemetry on every table row and overloads ingestion; the more direct action is to use appropriate verbosity and targeted instrumentation for meaningful events.
