I have created this Invoice group with this invoice numbering.
EUR/{{{year}}}/{{{month}}}/{{{id}}}
Now how, can i make the {{{id}}} reset back to 1 each new month.
Example:
In the month november i created 3 invoices.
EUR/2021/11/1
EUR/2021/11/2
EUR/2021/11/3
The next month in december, the ID must start with 1 again automatically. And not with 4, otherwise where are invoice 1, 2, 3 of the month December and that’s illegal in my country.
I don’t know if this is possible already or to create this with a cron job in some way?
Already thank you and keep up the amazing work.
best regards,
