Lecture Details

Primary Key Example - Key Fields and Foreign Keys

In this video I answer a question from a student learning SAP ABAP from the course Beginners Guide To ABAP at httpsacademy.saptraininghq.comcoursesap-abap-programming-for-beginners-online-training

The question goes like this What is the importance of Key Fields and Foreign Key

Key Fields come in a few different forms
A Table KEY - Is the Primary Key and it Identifies unique records in the table.
A Foreign Key - Used to link multiple tables together - They dont have to be unique - They point to unique values in reference tables (most of the time)
