Printer and Form Determination in Transportation Management 
You can use printer and form determination to control which printer is used and which type of form is to be printed.
You can use criteria to define which printer is to be used. If you do not define any criteria, the printer that you have specified in the user profile in your system is used automatically. Printer determination is the same for bills of lading and freight documents.
For automatic printing, you can use criteria to specify which form, in other words, which Smart Form, is to be printed.
Example
You can print bills of lading based on the country of origin or country of destination, or in accordance with the CMR or VICS standard.
A separate form determination is available for freight documents and bills of lading.
