# #10753 Cross-environment Master Data synchronization (same tenant)

> Cross-environment Master Data Management now allows subsidiary environments to synchronize master data from a source environment within the same tenant via an authenticated ODataV4 API, with capability negotiation, resumable streaming, inline media support, and OAuth2 transport.

[Pull request](https://github.com/microsoft/BCApps/pull/10753) · merged into `main` (BC30) on 2026-09-10 by dcenic · 48 files (+6701 -288), 36 AL · feature · tier official · reviewed (checked by Opus)

## What changed

- New IMDM Data Source interface with Local and Cross-Env implementations for flexible data source routing
- Source-side generic API with GetCapabilities, GetRecords (paged change feed), and LastModifiedAtPerTable for change detection
- OAuth2 client-credentials HTTP transport with in-session token cache and 429 backoff handling
- Media and Blob fields sync inline as base64 with per-field 512 KB cap to avoid SystemModifiedAt conflicts
- Connection Details wizard for setup similar to Intercompany, with security audit logging and mandatory privacy consent
- Behaviour changes for users or extensions.
