Hi,

If you need to print only the first line from the invoice lines, you can add an if condition inside the for loop to print only the first iteration.

In the code in the shared link, after this code:      , add an if condition to check whether it is first iteration, if yes, we will print else will skip.

                      <t t-foreach="lines" t-as="line">
                          <t t-if="line_index == 0">

                          t>
                      t>

Thanks
