How you will work through this lecture
After a supplier invoice is paid twice and 23,000.00 leaves the bank, treasury points to three approvals and IT calls duplicate prevention automated. The map shows the rule checks invoice numbers inside the ERP but not bank-file reruns, while an emergency user can create and transmit. Classify controls against risk paths rather than counting approvals, identify both gaps and define an interim compensating control.
A control is not a signature box; it keeps a defined risk within an accepted level. State objective, unwanted event, affected assertion and failure path before naming the control. For supplier payment, the objective is to pay a valid obligation to the right beneficiary once and on time. Then define who approves, on what evidence and limit, what the system blocks and how exceptions surface.
Preventive acts before completion, detective after movement and corrective after discovery. A strict block can halt valid activity, while a precise frequent detector may be economical, but detection delay matters when cash may not return. Strong design states where an event stops, where it surfaces and how it is corrected.
Manual controls depend on human judgement; automated controls execute configured rules; IT-dependent manual controls rely on system reports plus review. Test configuration, change access, input fields, interfaces, blanks and change log. Duplicate blocking can fail through formatting or manual bypass; exception reports can omit entities. Classify what actually operates, not the policy description.
Break the cycle into capabilities: master data, initiation, approval, execution, recording and custody. Conflict exists when one person can create and conceal or approve and execute. Test actual users and access use, not titles. A small team may need an independent, precise and timely compensating review; managerial familiarity is not a control.
Governance, ethics, risk assessment and oversight affect every cycle but do not prove one invoice was prevented from duplicating. State whether an entity-level control directly reviews an estimate or only shapes culture, and define scope and precision. Repeated overrides in one cycle may reveal a broader accountability weakness.
Design asks whether the control would address risk; implementation asks whether it was placed in operation; operating effectiveness asks whether it worked consistently through the period. Interviews, one observation and current configuration answer different questions. Keep conclusions and evidence separate.
The treatment starts from these documents. Follow the numbers to identify recognition date, amount, counterparty, reference and approval evidence before preparing the entry.
Facts and supporting evidence
The supplier returned a duplicate 23,000.00 payment recorded as a supplier receivable.
Correct treatment and entry
| Account | Debit | Credit |
|---|---|---|
| Cash at bank | 23,000.00 | |
| Supplier receivable — duplicate payment | 23,000.00 | |
| Total (SAR) | 23,000.00 | 23,000.00 |
Treatment and financial effect
The correction restores cash and closes the recovery asset; the preventive failure remains in the control record.
Reperformance starts from this case's own facts: The supplier returned a duplicate 23,000.00 payment recorded as a supplier receivable. Obtain the original source that proves this event. The training drawings Risk and control matrix, Access and segregation review explain field shape and reading order; they do not replace the case document or transfer their figures into it. Match entity, period, currency, reference and version to the process narrative, risk-control matrix, population and operating evidence, then confirm that the source supports the debit side (Cash at bank) and the credit side (Supplier receivable — duplicate payment). Missing ownership, date, reference or approval remains an open exception; a balancing journal or undocumented assumption does not cure it.
Remeasure from the facts before reading the proposed journal, then add it independently: total debits 23,000.00 and total credits 23,000.00. Debit detail: Cash at bank for 23,000.00. Credit detail: Supplier receivable — duplicate payment for 23,000.00. Link every line to the recognition or measurement rule explained in the lecture, then trace its reference and posting date. After posting, test the control test sheet, exception log and owner response. Equal sides prove arithmetic only, not the correct account, period or classification.
Before close, compare the correct treatment with the common alternative and record its specific effect: The receivable remains overstated by 23,000.00 and expense is understated equally. Do not close until the journal agrees with the conclusion, finding, risk rating and remediation plan and an independent reviewer can move from balance to account, reference and this event's own source. Keep the calculation, source version, journal identifier, reconciliation result and unresolved exceptions in the same workpaper. An attached file without a stated conclusion is not review evidence.
In an ERP, a role name or workflow box is insufficient. Extract create, change, approve and execute capabilities, duplicate rules, bank-file versions, overrides and configuration changes. Tie each automated control to fields and change management and each human review to a complete report, threshold and exception-resolution evidence.
Classify twelve risk paths and eight controls in the matrix, open the bank-rerun and emergency-user gaps, then propose an interim control with owner, frequency and evidence.

Use matching as a preventive control, then change quantities to identify what it blocks and what it cannot see, such as beneficiary or bank-file rerun.
Trace a 23,000.00 payment through control design and make eight decisions before concluding coverage.
What you haveObjective is paying the right supplier once.
The arithmetic in this case runs in the tool itself, which is open to you any time with your own figures.
Log every risk without a control, control without owner, evidence or precision, override without duration and review, and capability combining create, approve and execute.
This is not sent anywhere and not stored here. Write it down for yourself — in the workpaper you downloaded, or on paper.
A control begins with objective and risk, then timing, nature, dependencies and precision. Preventive stops before the event, detective sees afterward and corrective restores position. Automation needs configuration and supporting IT; segregation breaks capability. The map concludes covered, partial or uncovered—not a signature count.
How do you respond to a manager who says three approvals made a 23,000.00 payment controlled?
Answer every question. Getting them all right records this lesson; you may retry as often as you need.
Reading alone records nothing.
The complete applied walkthrough is available below while the recording is prepared.
We have a duplicate 23,000.00 payment and three approvals, but count does not answer risk. Start with the objective: right supplier, right amount, once. Map invoice, beneficiary, receipt and bank-rerun paths. Invoice-number blocking is preventive and automated but cannot see bank-file fingerprint; next-day reporting is detective and recovery corrective. Decompose access: an emergency user can create and transmit, a conflict regardless of title. Assign owner, frequency, precision, evidence, IT dependency and exception route. The conclusion is not eight effective controls; it is ten covered paths and two gaps requiring successful-item rerun prevention and independent daily review.
A monthly review may not address a daily pre-payment risk, and a million-level expense review may miss a 23,000.00 duplicate within normal fluctuation. Document frequency, lag, threshold, expectation, exception handling and authority. Precision must match potential loss and population size and should lead reviewers to investigable items.
Exception paths need requester, approver, reason, duration, ceiling, evidence, independent reporting and expiry. Execution cannot self-justify and self-review. Analyse exception rates, age and concentration; if 40% bypass the route, design, data or operations are failing. Later approval cannot cure cash released before beneficiary verification.
Map objective, risk, assertion, control, owner, type, frequency, precision, system, evidence and supporting IT control. Call a control key only when it closes a material risk path and can be tested. Five signatures on the same evidence are not five layers; a manual bypass may remain uncovered. Conclude covered, partly covered or uncovered and update after system, product, authority, test or loss changes.
Facts and supporting evidence
40,000.00 went to the wrong beneficiary and the valid supplier remains unpaid.
Correct treatment and entry
| Account | Debit | Credit |
|---|---|---|
| Receivable from unintended beneficiary | 40,000.00 | |
| Cash at bank | 40,000.00 | |
| Total (SAR) | 40,000.00 | 40,000.00 |
Treatment and financial effect
The outflow creates a recovery right and does not extinguish the valid supplier liability.

Facts and supporting evidence
Audit reversed an unauthorised manual journal charging 75,000.00 maintenance against an accrued liability.
Correct treatment and entry

Treatment and financial effect
The reversal restores both accounts while create-and-approve access is handled as a control gap.
