A bill of materials consists of rows
(horizontal) and columns (vertical). You can change the number of columns, for
displaying different types of information per column. With different types of
information we mean i.e. the product description, brand, material, quantity etc.
All basic data an properties, that have been entered in Product Information
Center, can be displayed in a column. When you have added the property "Ex
certificate" to the product in PIC, then you can setup a column to display
this data in your bill of materials.
In actual practice, there is no limitation to the number of columns that you can add to your bill of materials (max.32000).
