[Pull request](https://github.com/microsoft/BCApps/pull/10209) · merged into `main` (BC30) on 2026-08-14 by JesperSchulz · 4 files (+8 -25), 3 AL · other · tier official · reviewed (checked by Opus)

## What changed

- AA0471, AA0472 and AA0474 are moved from None to Error in base.ruleset.json
- AA0472 had no violations, so its override is simply removed
- Missed amount fields in Withholding Tax Entry and WHT Empl. Ledger Entry Ext now use AutoFormatExpression = Rec."Currency Code"
- WHT Threshold Accumulator gets an empty AutoFormatExpression because it only holds LCY amounts
- AA0473 and AS0112 keep their overrides because CI found hundreds of violations
