Research about some Logic Invoice topics

[Bruno Marques]

Hi guys, I'm studying the Logic Invoice but I need the help in the some topics to found in the program like:

-Tables with relationship N : N.

-Tables with relationship 1 : N.

-Reports, which have table joins (JOIN).

If someone can help me with this and give examples on the code and tables, I Will be very thankful !

Hmm...it's best to look into the database and determine it yourself. Usually tables that are linked have something like invoice to invoice_item etc.
