How to group Purchases to print them together?

[edgy forum]

Working on an ERP System that should be used in a Company where Purchases = Devices given to the User to work on.

I have a Mask where we can input the Customer Name and what he exactly gets. This then gets written into the Database with User ID and everything else.

How could I group more than one Database entry if it gets written into the Database in one Purchase? So I can then print everything that the User got in one Purchase

is adding a specific database field to every purchase made at the same time a good idea or can i group purchases made with the same timestamp together to print as one?

You would be better off making an "Order" or "Purchase" model to group them together

think of it as a "group of purchases"
