Document positions - Label and display columns
Below the header area on the Document Design page, you will find the areas "Document positions - Label columns" and "Document positions - Display columns".
Here you can overwrite the column titles (e.g. Product, Description, Quantity, Unit Price, Total) and specify whether quantity, unit price or tax rate should be displayed in the positions.
For each field, you can enter an individual label. You can store these in four languages: German, English, French and Italian.
