I imported orders to Magento and during the import, invoices and creditmemo have been created.
But I want to change the increment_id of these invoices/creditmemo so that it'll be coherent for accounting.
I update the increment_id in the database in the bases sales_flat_invoice and sales_flat_creditmemo. And I purged the caches before reloaded the admin panel page. But in the admin panel, there are the old numbers.
What can I do to update these id and make them visible from the admin panel ?
Or is it possible to generate the invoice and creditmemo choosing the id ?
