[Read the post](https://www.bertverbeek.nl/blog/2025/05/23/document-amount-on-purchase-invoice-header/) · Discover MS BC - Bert Verbeek (Bert Verbeek) · 2025-05-23 · 254 words · tier community · reviewed (checked by Opus)

> Business Central 2025 wave 1 adds a feature to compare document-level totals with line-level amounts on purchase invoices, preventing posting discrepancies and ensuring data accuracy. The feature requires setup in Purchases & Payables and validates that header amounts match line totals, including VAT considerations.

## Key points

- Feature compares Doc. Amount Incl. Tax field against sum of tax amounts on purchase lines during posting
- Must be enabled in Purchases & Payables Setup before fields appear on purchase invoices
- Users enter total amount in Doc. Amount Incl. Tax field; Doc. Amount Tax auto-calculates from lines
- Posting fails with error if amounts don't match, preventing incorrect document entries
- VAT Difference allowance setting is factored into the validation logic

## AL objects mentioned
