Can't Use my custom invoice template

[Richmond Fiko]

Hello,

I have a strange behavior in tryton 4.2 invoice module.
I create some custom invoice report template. All is OK when I try to print invoice in
different state until it come to posted state. At this state, the base invoice model is printed
for any template I try. Is it normal? How can I print my custom template when invoice is in posted state?

Hi,

It really depend on how you customized the report.
When you post an invoice, the system store a copy the report result. And
it use this copy for any further print.
If you do the override using a module, you must follow
https://tryton-readthedocs.readthedocs.io/projects/server/en/latest/topics/reports/index.html#replacing-existing-tryton-reports
This is to ensure that only one ir.action.report is linked to account.invoice.
Or you can just upload in the database another template on the default
report action.

I explain: I have 3 invoice templates, each template must be print according to a special case. It is not interesting for to keep a default model... So I need to print my custom model when invoice is posted because accountants will use the invoice sequence to track its.

Of course but it's a bit difficult and it's there because quite often
there is a legal requirement to be able to produce the invoices
exactly as they were produced originally.

You can still have a unique template containing your three templates
and a choice on the top of the file to choose the right template
from a value defined somewhere.

I don't understand as sequences are not related to relatorio
templates.

Not really because it is a requirement in most of the countries to
always re-print the document as it was when posted.

Indeed Tryton takes the first action it found to print the invoice.
I filled https://bugs.tryton.org/issue7646 to improve the situation.
For now, the best is to have a single template with a big switch/case
for the three layout.
