I'm programming a new DB for a natural health professional. Everything's fine, but if it comes to create the invoice, I want to enter the date of the therapy and the associated services.
With my actual solution I need to enter a date for every single service. I would like to enter a date and then the associated services, then the next date and the associated services and so on.
In one invoice should be more than one therapy date.
How can this be done correctly?
I tried with a statistic field, but that doesn't work for me. Problaby because I did it completely wrong .
Looking forward to hearing your replies.
