Hello,
The file is located in the addons directory account/report/invoice.rml
The best solution will be to create an addon that override you current report.
You can do it in XML
`
<report
auto="False"
id="account.account_invoices"
model="account.invoice"
name="account.invoice"
rml="my_addons/report/invoice.rml"
string="Invoices"
attachment="(object.state in ('open','paid')) and ('INV'+(object.number or '').replace('/',''))"
attachment_use="1"/>
`
By just replacing the rml attribute to your file path.
Else you can try c2c_webkit_report
to have HTML based report, they may be easier to customize as you do not have to know RML.
Thank you for your replies. But I have modified and even changed the name of "account/report/invoice.rml", and it didn't have any effect on the client side. Do you know where I could check that this is the right file ?
Yes you can check the path of the rml used from here Settings/Customization/Low Level Objects/Actions/Reports. search for object "account.invoice" and edit the entry in form view . The main reason why you don't see the effect is because of the argument "reload from attachment"
This will print the report from the attachment. Try to delete the attachment to see the effects.
