• Key Concepts: 
  A reference field is a field in an ABAP Dictionary table that references another table. It is used to link two tables together, allowing data from one table to be used in the other. The reference field contains the name of the other table and the key fields of that table. 
  
  How to use it: 
  To use a reference field, you must first create a foreign key relationship between the two tables. This is done by creating a foreign key in the referencing table that points to the referenced table. Once this relationship is established, you can then create a reference field in the referencing table that points to the referenced table. This will allow you to access data from the referenced table in the referencing table. 
  
  Tips & Tricks: 
  When creating a reference field, it is important to ensure that the data types of the key fields in both tables are compatible. This will ensure that data can be properly retrieved from the referenced table. Additionally, it is important to ensure that all of the key fields in both tables are included in the reference field.
