Hi,

This occurs when the Item ledger entry you are trying to apply the purchase credit memo to has a fixed application (a permanent link between entries).

Business Central cannot reapply the credit memo because the existing application must be removed first.
You can try and follow the steps below:-
How to Resolve

Go to Application Worksheet:
Search → Application Worksheet.

Select the Item and locate the applied entries.

Unapply the application.

Reapply the entries correctly, then post the purchase credit memo.

Sumit Singh, your reply appears AI-assisted. The application worksheet is for item entries, not vendor entries.

Hi,

That error usually means the credit memo is trying to automatically apply against an invoice or entry that is already fully or incorrectly applied. Business Central is expecting an open entry to offset but finds a fixed application in place that cannot be unapplied during posting.

What you can do:

1. Go to Purchase > Application Worksheet.
2. Find the vendor and review the applied entries. Look for the invoice/credit memo combination that has been "fixed applied."
3. Unapply the existing application (remove the fixed link) and reapply the correct entries manually.
3. Once unapplied, try posting the purchase credit memo again.

If you don’t usually use the Application Worksheet, that’s because in most cases the system auto-applies cleanly, but in this case, there’s a mismatch or fixed application that blocks it.

This error is more common if:

> Someone manually fixed applications in the vendor ledger.
> A partial payment/credit was applied earlier.
> The credit memo references a document already settled.

So the solution is simply: unapply and clear the fixed application > then reapply.

If you’re not sure which entry is causing it, check the vendor ledger entries for that vendor and see which document has a fixed application.

Thanks

You need to unapply the application, as the entry is already applied. Please use the application worksheet to unapply and then reapply. Please check this blog

Thanks, @Valentin Castravet for pointing that out. It was my mistake, though I have shared the correct links and screenshot however mistakenly mentioned the Vendor instead of Item.
