• Key Concepts: 
  Foreign key dependency is a type of relationship between two tables in the ABAP Dictionary. It is used to ensure that data in one table is consistent with data in another table. This type of relationship is created when a foreign key field in one table references a primary key field in another table. 
  
  How to use it: 
  In order to create a foreign key dependency, the foreign key field must be defined as a reference to the primary key field in the other table. This can be done by selecting the “Reference” option when creating the foreign key field. Once this is done, any changes made to the primary key field will automatically be reflected in the foreign key field. 
  
  Tips & Tricks: 
  When creating a foreign key dependency, it is important to ensure that the data types of both fields are compatible. If they are not, then the relationship will not be created correctly and data consistency will not be maintained.
