[Pull request](https://github.com/microsoft/BCApps/pull/12309) · merged into `main` (BC30) on 2026-10-06 by darjoo · 2 files (+66 -7), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Prevents stack overflow and out-of-memory errors when adding tables to Configuration Packages with field name collisions
- Replaces unbounded recursion with bounded loop using counter suffix approach
- Ensures suffix always fits within 30-character field name limit by shortening base name first
- Maintains backward compatibility for existing packages and correctly resolved names
- Added tests verifying behavior with maximum-length field names that previously caused hangs
- Behaviour changes for users or extensions.

## AL objects touched
