## TL;DR
Fix this in fixed assets by acting on the exact problem first: identify who closed the asset period early from the period audit log, verify no depreciation journal posted for the month, run depreciation for the missed month as a prior period adjustment in the current open period, and disclose the timing in the close notes. 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.

fixed asset depreciation run failed error asset period already closed
```

## Use this when
- The operation in fixed assets fails with this exact problem: fixed asset depreciation run failed error asset period already closed.
- 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 fixed assets 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: identify who closed the asset period early from the period audit log, verify no depreciation journal posted for the month, run depreciation for the missed month as a prior period adjustment in the current open period, and disclose the timing in the close notes. 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 fixed assets 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

### fixed asset depreciation run failed error asset period already closed
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 fixed asset depreciation run failed error asset period already closed fails error
The how to phrasing for the same failure in fixed assets. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### fixed assets 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
If depreciation never ran, assets and accumulated depreciation are both understated, and a labelled prior period adjustment restores the amounts without reopening a period other work has moved past.

## 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: fixed assets 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.
