3 AL/BC patterns from CURABIS's internal automated-testing training material (#158)
* Add 3 more AL/BC patterns from CURABIS Academy testing course material Third batch from CURABIS ApS: item-ledger-entry document-no lookup after Ship-and-Invoice posting, TestPage.Visible()/.Enabled() as the mechanism for verifying field UI state, and LibraryUtility.GenerateGUID() for collision-free test fixture values. * Address Jesper Schulz-Wedde's review on PR #158 - use-generateguid-for-unique-test-fixture-values.md: GenerateGUID() is a Code[10] number-series value, not a real GUID; truncating it with CopyStr for a shorter field cuts off the changing digits. Point to GenerateRandomCode/GenerateRandomCodeWithLength/GenerateRandomXMLText instead, which verify uniqueness against the actual table. - Split use-testpage-visible-enabled-to-verify-field-ui-state.md: drop its editability claim (the sample opens with OpenView() and asserts Enabled(), which verifies enabled state, not editability — Editable() and Enabled() are distinct TestField methods). New companion article use-testpage-editable-to-verify-field-editability.md covers Editable() with OpenEdit() specifically. - Wire GenerateGUID/CopyStr and TestPage Visible/Enabled/Editable cues into al-testing-review.md, and the Item Ledger Entry/Last Shipping No. posting cue into al-data-modeling-review.md. The Item Ledger Entry article itself was independently verified against current BCApps source and needs no changes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Address second round of Jesper Schulz-Wedde's review on PR #158 - use-generateguid-for-unique-test-fixture-values.md/.good.al: documented each LibraryUtility helper's actual behavior, verified against LibraryUtility.Codeunit.al. GenerateRandomCode opens the target table as a temporary RecordRef, so despite taking TableNo it never checks real data. GenerateRandomXMLText performs no table lookup at all. Only GenerateRandomCodeWithLength/GenerateRandomCode20 (capped at Code[10]/ Code[20]) genuinely verify against the real table. Fixture switched to GenerateRandomCodeWithLength where the comment claims verified uniqueness. - al-testing-review.md: rewired the cue to catch the actual anti-pattern (hardcoded literals, hand-built uniqueness, short-field GUID truncation) instead of only matching the compliant GenerateGUID()+CopyStr shape; broadened tokens to include TestPage, Library - Utility, and .Visible()/.Enabled()/.Editable(). - al-data-modeling-review.md: restricted the Item Ledger Entry Last-Shipping-No. cue to sales combined posting; purchase combined posting is Receive+Invoice and uses different fields entirely. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Fix remaining correctness issues from Jesper's 2026-09-15 re-review - use-generateguid-for-unique-test-fixture-values.md: narrowed the collision rule to primary-key/unique-lookup fields - an ordinary descriptive field carries no uniqueness constraint, so a hardcoded or deterministic value there isn't the anti-pattern (the article and its al-testing-review.md worklist cue both said "primary-key or descriptive field"). Also corrected GenerateRandomCode: it opens its target table as a temporary RecordRef that starts and stays empty, so its repeat/until loop always exits after one iteration and never retries even within a single test run - the "non-colliding within a test run" claim was false. It's the rightmost N characters of GenerateGUID()'s sequential series, so a short field's value cycles (Code[1] repeats every 10 calls, Code[2] every 100). Verified against LibraryUtility.Codeunit.al in the BCApps reference clone. - item-ledger-entry-document-no-follows-last-shipping-no: both fixtures called FindSet() without consuming its optional Boolean, which raises a runtime error on an empty result set - the opposite of the article's own claimed "silently matches zero rows, no error" behavior. Wrapped in `if ... then;` per the existing guard-database-reads.good.al idiom. - al-data-modeling-review.md: widened both not-applicable scope clauses (intro and outcome) to include dimension wiring, posting- routine structure, and Item Ledger Entry document-number lookups - the leaf declared itself not-applicable outside setup/master/key/ numbering/block/audit surfaces despite having a targeted cue for this PR's own new article. - Converted this PR's 8 plain-backtick "See sample: `x.good.al`." references (across all 4 new articles) to the READ-convention markdown-link form required by Knowledge-Retrieval.ps1. Rebased onto upstream/main (one conflict in al-data-modeling-review.md intro wording, merged). * Stop routing GenerateRandomCode20 as compliant for shorter fields al-testing-review.md's cue presented GenerateRandomCodeWithLength and GenerateRandomCode20 as interchangeable options for "a shorter field needing real verified uniqueness." They aren't: verified against LibraryUtility.Codeunit.al, GenerateRandomCode20 truncates GenerateGUID()'s sequential value down to the target field's length by keeping the leftmost (slowest-changing) characters via PadStr, so its retry loop against a field shorter than 20 can churn through the same truncated prefix for a long time. GenerateRandomCodeWithLength has no such problem (it generates exactly the requested length of random text). The knowledge article itself already scoped GenerateRandomCode20 to Code[20] correctly - only the skill cue needed narrowing to match. --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

18 AL/BC patterns: style, data-modeling, web-services, appsource, breaking-changes, performance, testing (#156)
* Add 18 community AL/BC patterns across style, data-modeling, web-services, appsource, breaking-changes, performance, and testing Contributed by CURABIS ApS, generalized from patterns observed across real AppSource/PTE development. Each article follows the knowledge file format (frontmatter, Description/Best Practice/Anti Pattern, sibling .good.al/.bad.al samples). * Address Jesper Schulz-Wedde's review on PR #156 - Rename 3 articles so their .good.al/.bad.al companion stems match (do-not-change-primary-key, testfield-required-setup-field, al-identifiers-english), fixing the R14 orphan-sample errors. - do-not-change-primary-key.good.al: include Flow in the new table's own primary key so it actually models the discriminating dimension. - al-build-output-must-not-pollute-project-root.md: drop the unsubstantiated AL0197 causal claim and the non-existent al.outputPath setting; reframe as build-artifact hygiene sourced from ALTool --outfolder / al_build outputPath. - prefer-email-module.md: Email Message is Codeunit 8904, not a table; distinguish it from the underlying Sent/Outbox/Draft storage. - file-datatype-saas.md: File.Open/Create/Read/Write fails to compile against a Cloud-scoped project, it does not compile and silently fail at runtime. - namespace-must-be-verified-from-source.md: narrow to "resolve from the referenced object's source or symbols," since source-file line one is not the only authoritative source (symbol packages, comments before the namespace line). - test-data-must-be-random-and-complete.md: drop "assume an empty database" and "collision-free" absolutes; reframe around independence from unrelated business records and reserving explicit values for scenario-defining inputs. - binary-choice-must-be-boolean.md: scope to genuine true/false semantics, not mechanical two-member-enum-to-boolean conversion. - document-report-word-layout.md: scope down to a sourced Microsoft Learn recommendation instead of an unconditional performance guarantee; cite the three Learn pages. - Wire the new articles into their review skills' candidate-selection signals (file-datatype-saas, prefer-email-module, namespace-must-be-verified-from-source, var-parameters-require-an- addressable-variable) so they can actually enter a worklist. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Fix dimension-management-wiring.md: ValidateShortcutDimCode and CreateDim do not exist on the current DimensionManagement codeunit Verified against microsoft/BCApps: the real master-table validation procedure is ValidateDimValueCode (or ValidateShortcutDimValues when a DimSetID is also needed), and the real document-side inheritance procedure is GetDefaultDimID, not CreateDim. Caught from Jesper Schulz-Wedde's review thread, which had been partially hidden by GitHub's comment folding. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Address second round of Jesper Schulz-Wedde's review on PR #156 - dimension-management-wiring.md/.good.al: split into the two distinct models the article was conflating - master data (Default Dimension records via ValidateDimValueCode/SaveDefaultDim) vs. transactional/ document data (a single Dimension Set ID assembled via AddDimSource + GetDefaultDimID, verified against BCApps' ExchRateAdjmtProcess.Codeunit.al). Added a compiling document-table example alongside the existing master table one. - Deleted api-page-flowfields-must-be-calcfields (.md/.good.al/.bad.al): Microsoft's own FlowFields documentation states a FlowField used as a control's direct source expression is automatically calculated on any page - no API-page exception is documented, and none could be reproduced. - prefer-email-module.bad.al/.md: Codeunit Mail has no Send/GetErrorDesc members; fixed to the real current 7-argument CreateMessage signature, and corrected the claim that the legacy path "still runs" - its base implementation no longer sends anything, only raises integration events. - check-post-line-batch-pattern.md/.good.al: reframed from a universal invariant to the standard shape, naming the real Gen./Item/CA/Res./Job/ Insurance/Mfg. Item/FA Jnl.-Check Line/-Post Line/-Post Batch codeunits it's based on. Added the missing Check Line companion codeunit so the good fixture is internally complete. - test-data-must-be-random-and-complete.good.al: removed leftover "collision-free" wording contradicting the already-corrected article text. - fixed-choice-set-must-use-enum-not-integer.md: removed the reintroduced state-count heuristic ("the line is the state count"), aligned with binary-choice-must-be-boolean.md's semantics-based distinction. - namespace-must-be-verified-from-source.md: removed the false claim that the compiler and AL Language Server use different namespace-resolution rules. - intrinsic-al-functions-must-use-modern-casing.md: removed the unverified claim that PascalCase is the VS Code formatter's default output. Worklist completeness: added cues for the 8 rules in data-modeling, testing, performance, and web-services that had none (Jesper's explicit ask), plus the same gap in all 7 style rules from this PR (not explicitly named this round, but the identical systemic issue) - 15 cues total across al-data-modeling-review.md, al-testing-review.md, al-performance-review.md, al-web-services-review.md, and al-style-review.md. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Fix remaining correctness issues from Jesper's 2026-09-15 re-review - dimension-management-wiring: SaveDefaultDim's third argument is the shortcut dimension number (1-8), not the field's AL field ID; the fixture passed FieldNo(...) = 10. GetDefaultDimID's InheritFromDimSetID must be 0 when recomputing after the linking record changes, not the document's existing Dimension Set ID (which would retain the previous customer's leftover dimensions). Verified against DimensionManagement.Codeunit.al and BankDepositHeader.Table.al in the BCApps reference clone. - check-post-line-batch-pattern: "Post Line writes exactly one line to the ledger" overclaimed - Gen. Jnl.-Post Line alone calls InsertGLEntry from a dozen call sites (balancing entry, VAT, currency rounding, deferrals) and can write several G/L Entries per journal line. Reworded to "posts exactly one journal line" and softened the "distinct, non-overlapping responsibilities" absolute. - namespace-must-be-verified-from-source.bad.al: dropped the "resolves in a local build, fails in VS Code" comment (taught an inherent compiler/language-server disagreement that isn't real); reframed as stale/cached symbols, matching the prose fix already made. - file-datatype-saas.good.al: replaced the deprecated 5-argument UploadIntoStream overload with the current 2-argument one, and actually staged through TempBlob as the article's own Best Practice instructs (the declared TempBlob variable was previously unused). - test-data-must-be-random-and-complete: no longer treats a short-but-valid value as defective merely for being "underfilled" - AL field lengths are maxima, not minimums. Scoped to missing values or a scenario with an explicit length/format requirement (e.g. a truncation test). Updated the al-testing-review.md routing cue to match. - stored-derived-fields-must-not-be-exposed-directly: stopped mandating source-field exposure as part of the core pattern: the good fixture exposed only one of the derived value's two inputs (Hours Used, not Budgeted Hours), making the claimed "so the consumer can verify it" impossible. Reframed as an optional, all-or-nothing addition and fixed the fixture to expose both inputs. Rebased onto upstream/main to resolve conflicts in al-breaking-changes-review.md, al-data-modeling-review.md, al-performance-review.md, and al-style-review.md against merged PRs #148 and #153; all sides' worklist tokens/cues retained. * Fix remaining READ-convention sample links across this PR's 18 articles The same plain-backtick "See sample: \`x.good.al\`." form fixed on al-methods-limited-during-write-transactions (PR #161) turned up repo-wide on 15 more of this PR's articles - Knowledge-Retrieval.ps1 requires the markdown-link form to associate a sample with its article. All 16 fixed; the four local validators (frontmatter, knowledge-index, knowledge-retrieval, review-fixtures, skill-index) pass. * Fix two merge-critical correctness issues from Jesper's 2026-09-22 review - api-page-key-fields-must-be-editable-on-insert.good.al and stored-derived-fields-must-not-be-exposed-directly.good.al: both were writable API pages missing DelayedInsert = true, contradicting this repo's own api-page-delayedinsert-true rule - the canonical "good" samples were teaching code BCQuality itself flags. - dimension-management-wiring.good.al: UpdateDimensionSetID exited early when Customer.Get failed, leaving the previous customer's shortcut dimension and Dimension Set ID in place - the same staleness bug the InheritFromDimSetID = 0 fix (from the prior review round) was meant to prevent, just triggered by a failed lookup instead of a successful one. Now clears the shortcut field and recomputes with an empty source list on a failed lookup too, so GetDefaultDimID correctly returns an empty Dimension Set ID instead of never running. --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

knowledge: three false-positive guards from BCApps PR 10277, 10278 and 10346 (#146)
data-modeling: add insert-only-transfer-may-rely-on-caller-cleanup. A filter-and-insert transfer routine was reported for stale rows and duplicate keys even though the field OnValidate trigger calls a sibling cleanup procedure that clears the same range immediately before it. Deciding this requires reading the caller, so the article asks reviewers to trace call sites and keeps uncleared or mismatched-filter paths reportable. appsource: scope two-level-namespace-replaces-object-affix-not-extension-member-affix to apps that actually configure a mandatory affix. AS0011 only runs when AppSourceCop is enabled with a mandatory affix; a first-party in-box app that ships no such configuration is not subject to it. The member-affix requirement itself is unchanged for apps that do configure one. testing: allow permission-tests-must-lower-the-execution-context to accept a composed role. The article demanded the exact permission set under test be assigned directly, so a test that lowered permissions through a role including that set and then asserted WritePermission was false was reported as a coverage gap. What matters is the effective context plus a boundary assertion, not which object the test names. Co-authored-by: wenjiefan <wenjiefan@microsoft.com> |

Complete AL review knowledge readiness (#108)
* Complete AL review knowledge readiness Fill telemetry and Query coverage, strengthen thin review domains, correct audited content defects, and add deterministic cheap-model evaluation and reference-integrity safeguards. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9825b012-e653-496a-9310-c1f4b6f8ac27 * Generalize review fixture discovery Derive smoke cases from the leaf, domain, and paired-sample conventions so new leaves require no scoring-contract changes. Keep only exceptional selection/context overrides and fail when retrieval metadata cannot rank the selected article.

Add data-modeling and appsource knowledge articles (MICROSOFT layer) (#65)
Author 7 remedial BCQuality knowledge articles plus good/bad AL samples (21 files) covering AL master-table and data-model design: - data-modeling: master No. from number series in OnInsert; use codeunit "No. Series" not obsolete NoSeriesManagement; setup table is a singleton; set Last Date Modified in OnModify and OnRename; enforce Blocked in referencing code not in the master. - style: ApplicationArea required on page controls (AS0062). - appsource: object affixes prevent collisions (AS0011). Clean-room authored from own BC knowledge; specifics verified against public sources only (learn.microsoft.com, microsoft/BCApps). Introduces two new domains (data-modeling, appsource).
