# All new goodies about AL Namespace in BC 2025 wave 2

> AL namespace additions in Business Central 2025 wave 2 (BC27): a new AL namespace field on the All Objects with Captions table, Record ID formatting with format type 9 to show the namespace, and evaluating a Record ID against a fully qualified namespace. All three are demoed.

[Watch on YouTube](https://www.youtube.com/watch?v=KmuTVkodRXM) · Business Central Musings · 2025-10-20 · 10:37 · tier community · reviewed (checked by Opus)

## Overview

The video compares BC26 and BC27 and shows that the All Objects with Captions table now has an AL namespace field. It is a Text 500 field. It is not visible on page 9174 in the base application, but the page is extensible, so it can be shown through a page extension. The demo also covers the System Reflection namespace, which the table belongs to, and analysis mode.

The second half covers Record ID. A Record ID can be formatted with format type 9 to show the fully qualified AL namespace of its record, and it can be evaluated against a fully qualified name such as Microsoft Sales Customer to test which namespace a record belongs to.

## Key points

- BC27 adds a Text 500 field called AL namespace to the All Objects with Captions table.
- The field is not shown on page 9174 in the base application; the page is extensible, so add the field with a page extension.
- The All Objects with Captions table is in the System Reflection namespace.
- Formatting a Record ID with format type 9 returns the fully qualified AL namespace of the record.
- A Record ID can be evaluated against a fully qualified namespace to test whether a record belongs to it.
- The example fully qualified name for Customer is Microsoft Sales Customer.
