[Pull request](https://github.com/microsoft/BCApps/pull/9789) · merged into `main` (BC30) on 2026-07-31 by DhavalMore88 (community contribution) · 7 files (+506 -10), 5 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Removed the GenJnlLineApplID = '' guard so the netted payment amount is saved to the journal line in the Applies-to ID case
- Added a re-entrancy guard in PmtTolGenJnl to stop recursion when Amount is validated
- Vendor payments applied to several invoices in foreign currency no longer double the discount tolerance
- Fix made in the W1, CH, FR, IT and NL layers; customer path unchanged
- Regression tests added in W1 and IT vendor payment tolerance test codeunits
- Behaviour changes for users or extensions.
