The previous LLM-generated knowledge files contained factual
hallucinations. The most visible was the claim that `FindFirst` /
`FindLast` "forces a full-table scan" on an unfiltered record - it does
not; those APIs return a single row via the current key.
Other inaccuracies the audit found and fixed:
* `FindSet(true)` was described as "taking a LockTable". The correct
upstream phrasing is that `FindSet(true)` sets
`ReadIsolation::UpdLock` on the read. UpdLock and LockTable are
related but distinct mechanisms.
* The list of production-scale tables had been invented beyond the
upstream source (e.g. "Detailed Cust. Ledg. Entry") without a
citation. The regenerated list matches the ten tables upstream lists
with their P95 row counts.
* `SetLoadFields` guidance had been augmented with an extra mechanism
claim ("the database resolves the filter using the index without
hydrating the value") not present in upstream.
Approach: full regeneration of `microsoft/knowledge/` from the six
upstream BCApps Code Review instruction files, with Microsoft Learn /
the AL language reference as a secondary source. Every claim in every
regenerated file is anchored to a verbatim upstream quote (or a Learn
URL); the audit trail lives in artifacts/trace-<domain>.json on the
session workspace.
The PR #11 transaction/error-handling cluster is preserved verbatim:
* performance/understand-implicit-transaction-boundary.md
* performance/codeunit-run-as-atomic-sub-operation.{md,good.al,bad.al}
* performance/codeunit-run-requires-prior-commit-inside-transaction.{md,good.al,bad.al}
* performance/use-tryfunction-for-error-catching-not-rollback.{md,good.al,bad.al}
* performance/avoid-commit-inside-loops.{md,good.al,bad.al}
* security/commitbehavior-attribute-scopes-explicit-commits.{md,good.al,bad.al}
* testing/transactionmodel-attribute-governs-test-transactions.{md,good.al,bad.al}
These articles already cite Microsoft Learn and were carefully
cross-referenced; the regeneration skips their topics rather than
duplicating them.

# Option fields need `OptionCaption`, and its element count must match `OptionMembers` (CodeCop AA0221/AA0223/AA0224)
|
|
|
|
## Description
|
|
|
|
CodeCop AA0221 requires an `OptionCaption` on every option-type field that is not sourced from a table column (table-sourced option fields inherit the captions of the underlying field). AA0223 and AA0224 add two integrity checks: the number of comma-separated entries in `OptionCaption` must equal the number of entries in `OptionMembers`, and each caption must align by position with its member. The position alignment is what the platform uses to translate option values — the `OptionMembers` list never changes per locale, the `OptionCaption` list does. A mismatch in count or order produces silent corruption: the option `Released` shows the caption that belongs to `Pending`, and the bug is locale-dependent.
|
|
|
|
## Best Practice
|
|
|
|
`OptionMembers = Open,Released,Pending;` and `OptionCaption = 'Open,Released,Pending';` — same count, same order. When adding a new member, update both lines in the same commit.
|
|
|
|
See sample: `optioncaption-required-and-matches-membercount.good.al`.
|
|
|
|
## Anti Pattern
|
|
|
|
`OptionMembers = Open,Released,Pending;` with no `OptionCaption` at all (the user sees the raw English members and translation is impossible), or `OptionMembers = Low,Medium,High,Critical;` paired with `OptionCaption = 'Low,Medium,High';` — count mismatch, `Critical` displays as blank or carries the wrong caption depending on platform version.
