[Pull request](https://github.com/microsoft/BCApps/pull/9783) · merged into `main` (BC30) on 2026-07-31 by Shikhverma · 3 files (+121 -5), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Fixes posting failure for lot-tracked purchase returns reserved against the receipt entry when Exact Cost Reversing Mandatory is enabled
- When the return line is fully reserved against an item ledger entry and Appl.-to Item Entry is blank, the value is derived from the reserved entry
- No manual entry of the exact-cost link is needed any more
- Change made in the Purch. Line-Reserve codeunit; new test added and existing costing test adjusted
- Behaviour changes for users or extensions.
