Every license record has six fixed data fields and unlimited dynamic data fields where you can store additional information. You can create and name new fields which will be available to all license records afterwards.
Click on the line you want to edit and press the button “Edit”. A window appears that allows you to make the changes. You can also globally change the name of the field here directly by clicking the button. That will activate the possibility to edit the name of the field (see also 6.5.7 Change License Data Fields | „ Lizenz+Softwaremanagement/Mehr/Lizenzfeldnamen bearbeiten“).
