• Key Concepts: 
  Reference type is a data element in the ABAP Dictionary that defines the type of reference relationship between two tables. It is used to define the type of relationship between two tables, such as one-to-one, one-to-many, or many-to-many. It also defines the cardinality of the relationship, which is the number of records in each table that can be related to each other. 
  
  How to use it: 
  Reference type is used to define the relationship between two tables in the ABAP Dictionary. To create a reference type, you must first create a data element and then assign it to a table field. The data element must have a reference type assigned to it in order for it to be used as a reference type. Once the reference type has been assigned, you can then define the cardinality of the relationship between the two tables. 
  
  Tips & Tricks: 
  When creating a reference type, it is important to consider the cardinality of the relationship between the two tables. This will help ensure that the data is properly linked and that there are no inconsistencies in the data. Additionally, it is important to consider how often the data will be updated and whether or not there will be any changes in the structure of either table.
