# #10927 [Change Log] Preserve SystemId for unloaded record modifications

> Change Log Management now preserves the SystemId from persisted records when modifications are recorded without the record being loaded first, fixing incorrect null SystemId values in change entries.

[Pull request](https://github.com/microsoft/BCApps/pull/10927) · merged into `main` (BC30) on 2026-09-08 by onbuyuka · 2 files (+45 -1), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- When an incoming modification has a null SystemId, Change Log uses the persisted record it already loaded
- No extra database read; the populated-SystemId path and public signatures stay unchanged
- Fixes Changed Record SystemId on modification entries
- Change Log entries for failed inserts are a separate platform issue and are not addressed
- Adds a regression test for modifying a record by primary key without loading it first
- Behaviour changes for users or extensions.
