Update 28.4 for Business Central 2026 Release Wave 1 was released on 3 August 2026. Application build 28.4.53241, platform build 28.0.53152. A quiet month on features, mostly hotfixes, no localization updates.
Feature changes
- Payables Agent known senders, general availability. Skips redundant classification for vendor emails already seen. See release plan.
- Payments with the electronic document framework, general availability. Payment related documents now flow through the same pipeline as invoices and credit memos. See release plan.
- Peppol preview on the purchase draft page, public preview. Lets you review a Peppol electronic invoice before it becomes a full purchase document. Worth testing in a sandbox first. See release plan.
Good to know
- Field Service integration now respects the Dataverse Convert to Customer Asset setting. New uncoupled service items only create a customer asset when the setting is Yes. Existing coupled records keep syncing as before.
- The Copilot and agent data movement change flagged for 1 July 2026 is now in effect. Some environments on version 28.0 or later may process Copilot and agent requests in a different Azure geography. Check the Copilot and agent capabilities page to manage preferences.
Hotfixes worth knowing about
Platform hotfixes cover six issues this month, including a silent client crash tied to a missing SQL join on table extensions during CopyFilters, and implicit app dependencies binding to the highest published version instead of the control plane manifest.
Application hotfixes run past a hundred entries. A few worth flagging:
- Aged Accounts Receivable Excel report ignoring the user specified number of periods.
- Double counting of material consumption in the Inventory Valuation WIP report.
- Invoice total changing unexpectedly when a sales order line description is edited.
- Depreciation calculated on full asset value instead of the adjusted 80 percent base.
- Bin Capacity Policy allowing more than the maximum capacity on inventory movement line splits.
- Trial Balance Excel report showing incorrect amounts.
- New Azure OpenAI privacy notice approval required before using the Expense Agent capability.
Belgium gets three local fixes: the take payment discounts setting in the Suggest Vendor Payments EB routine, currency text wrongly included in payment XML exports when the FCY symbol option is selected, and the document check factbox not refreshing on purchase invoices.
