Hello, I wanted to propose a thing that I do not know if it is possible to do it. The idea is as follows:
After creating a dunning and after define a due date, the first level of dunning should be reached when the first 10 days after the due date have passed, the first payment reminder (the email ) should be sent. Then the 2nd dunning level should be reached after 20 days have passed, and the 3rd when 30 days have passed . When this 3 levels are done the system should change status from “Waiting” to “Final/Processed”.
1st level-after 10 days
2nd level-after 20 days
3 rd level-after 30 days
Here I want to know, what are the fields I should fill out and what I I should put on the field ‘’ overdue ‘’ to make it respect automatically send an email after passing 10 days after processing each level?
Ps:for now everything is going good with the module dunning but it sends an email just everytime I process the dunning, and me I want that this process sent an email after passing 10 days at the first level , then the second level after 20 days,… My problem here is how I should fill out the fields and what are the fields I should fill out to do this thing and sending an email after some days I define them ? .

So basically you want to be able to send a reminder for the reminder.
I think it should be possible to use the `notification_email` module with a trigger based on time. The condition could be `Eval('state') == 'waiting' & (Eval('since') - Eval('current_date')).days >= 10` and with `minimum_time_delay` set to maybe 10 days.
So the only missing part is to store on a field `since` when the dunning was set to waiting. And I think such field would be useful in many cases so it could be added in standard.

1/IHere i would to know where i should add this block of code and those fields should i add them on the module “notification\_email” after activate it or just put them on the model “'account.dunning.level” ?
2/ if we will use email\_notification module, so what’s the function of the Levels :SO herei have a question may make things for me more clear, i have thought from the beginning that `Levels help us to define the date when the email should be sent by using the field "overdue" and by processing the dunning, it passes to another level?`;, am i wrong , please can u tell me clearly what’s the function of this Level in the dunning module!?
3/About `[Issue 10722: Add date and age to dunning - Tryton issue tracker](https://bugs.tryton.org/issue10722)`
i have tested that by doing those steps:
I have trying create a payment term (see the image below please)
then i created a dunning (As shown in the following picture ):
in the field` Invoice Payment` , i filled it out as shown in the following picture :
in the `Procedure` field , i have define the first Level (email should be passed after 10bdays) as shown in the following picture :
and finally when i process the dunning still sent me the email once i process the dunning and not after 10 days
also the age give me “00:00” and the date is the day of today(as shown in the following image) !!?
i do no what’s wrong and what i should modify to reach my goal to send the email after 10 days and not of the moment when i try to process dunning!
