Overview

This section lists what has been deprecated or removed in the Business Central application. One page covers deprecated W1 features by release wave, from 2020 release wave 1 through 2025 release wave 2, with items such as API v1.0, Finance reports API, legacy Power BI apps, Intelligent Cloud Insights, Excel reports and configuration packages. Another page covers the table and field objects permanently deleted in 2025 release wave 1 (v26).

The deleted objects page lists more than 150 obsolete tables and fields in the Base App and localized versions (W1, AT, APAC, BE, CH, CZ), tied to the version 25.0 upgrade. The goal is better database performance, a more unified codebase across regions and less technical debt.

Start with the deprecated features page to check whether a feature you rely on is affected and in which wave. Then use the subtopic with uptake examples for practical guidance on moving off the North American bank reconciliation and deposits, user groups, and legacy views.
