## TL;DR
Fix this in Oracle Fusion by acting on the exact problem first: open the Oracle Fusion close validation message and work it source by source, payables invoices in draft accounting first, then receivables and cost items, fixing each named transaction in its own subledger rather than in the general ledger, and save the final clean validation report as close evidence. Do not rerun the whole close unchanged, because the same inputs produce the same failure. Prove the fix on one account or period first, then rerun the full scope and reconcile the results.

## Use this when
- The operation in Oracle Fusion fails with this exact problem: how to fix Oracle Fusion subledger accounting error period close validation failed fails error.
- The same failure repeats on retry with unchanged inputs.
- A close task, reconciliation, journal or reporting step is blocked until this is resolved.

## Not for this skill when
- The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
- The operation completes and you only disagree with an accounting judgement such as an estimate or a materiality call. That is a controller decision, not this failure.

## Steps
1. Reproduce the failure on one named account or period in Oracle Fusion and record the full problem text plus the account, period or journal involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: open the Oracle Fusion close validation message and work it source by source, payables invoices in draft accounting first, then receivables and cost items, fixing each named transaction in its own subledger rather than in the general ledger, and save the final clean validation report as close evidence. Verify: the single failing account or period now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring accounts, entities or periods that share the same checklist, schedule or sync, because this class of failure rarely affects only one account. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in Oracle Fusion on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the signed general ledger record, the subledger record or the bank record, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the close log so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

## Variant phrasings

The verbatim form searchers paste from the console, report or run log. Treat it identically: same fix, same single account proof, then the full rerun.

### How to fix - how to fix Oracle Fusion subledger accounting error period close validation failed fails error
The how to phrasing for the same failure in Oracle Fusion. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### Oracle Fusion troubleshooting for this failure
The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

## Why it happens
Validation failures name transactions in their source subledgers, and correcting them in the general ledger leaves the source record invalid, so the same validation fails again on the next close attempt.

## Edge cases
- The account was adjusted, reopened or revalued after the failing run started. Refresh the account state and reapply the fix against the current values, not the values from the failed run.
- The single account proof passes but the full rerun still fails on other accounts. Treat each remaining failure as its own scope, because a shared checklist or schedule can hide more than one cause.
- The source systems disagree on the correct value. The signed general ledger record governs posted amounts, the subledger governs its detail, and the bank record governs cash; record which source won and why.

Compatibility: Oracle Fusion at current versions, plus the general ledger, subledger or close tool the query names; no extra tooling beyond access to the source records needed to verify results.
