Document amount on Purchase Invoice Header

With the release of Business Central 2025 wave 1 there is a new feature added at the purchase invoice.
Well new feature? It was already present in the Dutch localization but with some enhancements it is now available in the W1 of Business Central!

What does the feature?

The tooltip maybe says it already:
Specifies if you want the Doc. Amount Incl. Tax field in purchase documents to be compared to the sum of the Tax amounts fields in the purchase lines. If the amounts are not the same, you will be notified when posting the document.
So when on posting you and the totals are correct from header and lines you get an error. Why do you want this? Just to compare on line level if you have entered it correctly.

How to

First you need to enable a setup in the “Purchases & Payables Setup”:

After that the two fields are visible on the Purchase Invoice:

In side the fields you have to enter the total amount of the lines. You only have to fill in the “Doc. Amount Incl. Tax”. The “Doc. Amount Tax” is filled in based on the lines (if they are inserted).

If the amount isn’t the same then you get an error when posting:

So in that case you cannot make any mistake if you entered the value from the purchase invoice!

NB: if you enable “Allow VAT Difference” in the setup of “Purchases & Payables” then he will take this also into account by checking it!
