- 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.

Write AL Identifiers in English Only
Contributions welcome — open a PR to refine or extend this article.
Description
All AL identifiers — variables, procedures, parameters, fields, object names, enum values, and label identifiers — must be written in English, regardless of the developer's native language. Translations are handled separately through captions, tooltips, and XLIFF files, never by writing Danish, German, or other non-English identifiers directly into AL source code. This is not a stylistic preference: the public microsoft/BCApps codebase, maintained by engineers of many nationalities across hundreds of thousands of lines of AL, uses exclusively English identifiers, with all localization handled via caption properties and XLIFF rather than by changing identifier names. On any multi-contributor codebase, non-English identifiers make the code unreadable to contributors who don't share that language.
Best Practice
Write every identifier in English, and translate developer intent rather than transliterating it — when a requirement is described in another language, the resulting variable, procedure, and field names should still read as English. Captions and tooltips may carry target-language text in the source file, with locale translations managed through XLIFF.
See sample: al-identifiers-english.good.al.
Anti Pattern
Using native-language identifiers such as a Danish variable or procedure name in AL source code, relying on the fact that the code still compiles and runs correctly. This makes the code unreadable to non-native-language contributors and mixes localization concerns into source that should stay language-neutral.
