Hi,

To add a field to a Qweb view from the GUI, you should go to Settings/Technical/Reports/Reports and then :

• Search for 'sale.order' report,

• Click on the link "Search for Qweb Views",

• Open the view named : report_saleorder_document,

• In the view, choose th place you want to insert your new field (x_Supplier)
  

• For example, to insert it after  the Saleperson name, add this code after the div of Salepersonn
  

<div t-if="o.x_Supplier" class="col-xs-3">
            <strong>Supplier:</strong>
            <p t-field="o.x_Supplier"/>
</div>

• Save the view.
  

• Test by printing a Sale order .

Hope it helps

Thank you Laurent OLIVIER.  I've tried that, but it did not work..  

I wanted to add next to the product description in the table, so I did below:  

When I tested it, the Supplier header showed up, but it's blank.  I guess the o.x_Supplier didn't work?

<table class="table table-condensed">                
<thead>                    
    <tr>                        
        <th>Description</th>                        
        <th>Supplier</th>

<tbody class="sale_tbody">                    
<tr t-foreach="o.order_line" t-as="l">                        
    <td>                           
    <span t-field="l.name"/>                        
    </td>                                                                  
    <td>                           
    <span t-field="o.x_Supplier"/>                         
    </td>
