Report Sales Invoice

Hi, Want to redesign te sales invoice report. I have super rights and now when i am in the the object designer and go to sections See the form but cannot display the fields : In the fields menu only a field number displayed and no other field’s. This only in the header. In the detail section it is Oke? all field are there. Help.

This is because the data item is based on the table integer. You can very easily check this when you look into the properties of any other field in that section. All fields will have a dataitem name in front of the field name. Unfortunately you cannot use the field menu in this case.
