Imagine this: You have generated your ACH payments in Microsoft Dynamics 365 Business Central and created a file to export to the bank. The next step is to post the payment. That’s when you find that one payment is not applied to the correct invoice, or perhaps that you have duplicate invoice numbers.
Has this ever happened to you? You might even try to modify the line but receive an error message that the line cannot be modified.
How do you fix this ACH payment mistake in Dynamics 365 Business Central? You can reapply the payment to another invoice, and that will fix your issue. To do this, highlight the line you want to change. Then click Process, Apply Entries.

On the Apply Vendor Entries screen, highlight the correct invoice line. Then choose Process, Set Applies to ID, and click the “OK” button. Please note: sometimes on this screen you might not see the Process, Line, Entry and More Options tabs. Instead, you will see three vertical dots. Click on those dots to see those options.

Now when you return to your payment journal, you will see that the old invoice is no longer visible but the box is blank. If you click the three little dots as shown below, you can verify that the right invoice is applied.

Once you click the three dots, the Apply Vendor Entries screen opens. You can see that the correct invoice is applied, the payment is fully applied and the balance is 0.

Another trick to prevent this from happening is to do a Preview Posting before generating the EFT file for the bank. Keep in mind that once the EFT file is generated, you typically cannot modify the transactions.
