To finish the current item return, click "F4:Ok". As a result, the previous page with the order line view on the item level shows the new value in the “Quantity already returned” column. 

To proceed with the mass return, click "F1:Back". 

As a result, the latest page from which you started an item return, is shown. For example, the latest page from which you started an item return is "Show related orders". If you click “F1:Back” when the item return is finished, the “Show related orders” page is shown. 

Notes

The filters, as applied on the "Show all orders" page, are preserved. So, you can easily continue the return process for similar items. For example, items with the same work location or from the same customer as the previously returned item. To reset all applied filters, click “Clear”.
