Via “Configuration- > Packaging material” you get to a list with all available packaging materials.

In the “Actions” column, behind each packaging material, there is a “Edit” button, which you can use to edit the data of a packaging material.

Only the “Name” field must be filled in.

An existing packaging material can, apart from the “name”, be completely overwritten with empty data records.

Finally, click Save to save the modified record.
