+<report id="report_deposit_slip"
+ model="deposit.slip"
+ string="Generic Deposit Slip"
+ report_type="qweb-pdf"
+ name="delivery_carrier_deposit.report_generic_deposit_slip"
+ file="delivery_carrier_deposit.report.deposit_slip"
+ />
```
It points to the `delivery_carrier_deposit.report_generic_deposit_slip` template, it must points to the translated template!
