  Key Concepts: 
  Foreign key association is a feature of the SAP Application Platform (AP) that allows two tables to be linked together. This is done by creating a foreign key in one table that references the primary key of another table. This allows data from both tables to be accessed and manipulated in a single query.
  
  How to use it: 
  To create a foreign key association, you must first create a foreign key in one table that references the primary key of another table. This can be done by using the ALTER TABLE command in SQL. Once the foreign key has been created, you can then use the JOIN command to access and manipulate data from both tables in a single query.
  
  Tips & Tricks: 
  When creating a foreign key association, it is important to ensure that the data types of the primary and foreign keys match. This will ensure that the data can be accessed and manipulated correctly. Additionally, it is important to ensure that the foreign key is indexed, as this will improve query performance.
