# #11138 [29.x][Bug Fix] Fix recurring journal background posting for IRS 1099 invoice lines (US)

> IRS 1099 subscribers no longer call Modify(true) on journal lines during validation, allowing background recurring posting to succeed without re-entering OnModify and triggering posting failure checks.

[Pull request](https://github.com/microsoft/BCApps/pull/11138) · merged into `releases/29.x` (BC29) on 2026-09-07 by Explorer986 · 2 files (+137 -2), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Removed redundant SaveChangesInGenJnlLine calls that caused Modify(true) to re-fire OnModify during background posting
- IRS field derivation still occurs but the owning caller now handles persistence
- OnModify guard still protects against user edits while background posting works correctly
- Added comprehensive tests validating scheduled posting works with IRS data sync and direct Modify still fails as expected
- No schema, permission, or upgrade impact
- Behaviour changes for users or extensions.

## AL objects touched
