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 https://academy.saptraininghq.com/cou...
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 don't have to be unique - They point to unique values in reference tables (most of the time)
