• Key Concepts: 
  A secondary table is a type of database table in SAP that is used to store additional information related to a primary table. It is linked to the primary table via a foreign key, which is a field in the secondary table that contains the same value as the primary key of the primary table. This allows for data from both tables to be accessed and manipulated together. 
  
  How to use it: 
  In order to use a secondary table, you must first create it in the ABAP Dictionary. This can be done by selecting the “Create Secondary Table” option from the ABAP Dictionary menu. Once created, you can then link it to the primary table by creating a foreign key in the secondary table that contains the same value as the primary key of the primary table. 
  
  Tips & Tricks: 
  When creating a secondary table, it is important to ensure that all fields in the foreign key are indexed so that data can be quickly retrieved from both tables. Additionally, it is important to ensure that all fields in both tables are properly defined and have appropriate data types so that data can be accurately manipulated.
