Unable to delete an invoice or a credit note. Error 'This operation is not supported'

Problem Statement

You may see these errors:

• "This operation is not supported when a credit note is applied on an invoice" when deleting an invoice.
• "This operation is not supported when allocations are present" when deleting a credit note.

These errors typically occur when an Adjustment credit note is created for the invoice, or when Refunds and Allocations exist for the credit note. You must remove the credit note allocated to the invoice before deleting the invoice, and remove Refunds and Allocations before deleting the credit note.

Note: This applies to invoices in Posted, Payment Due, or Not paid status.
