As an alternative of making claims for unallocated usage via the user interface in label.gvl, you can also add your claims to an Excel export of the unallocated usage. You can enter your claims in the export file, and subsequently upload your usage claims to label.gvl. This procedure is recommended if you have a larger volume of unallocated usage for which you want to submit claims. After the upload, there will also be an error file made available under “Unallocated usage“ > "Upload history“ if errors occur.
