• Key Concepts: 
  Multiple table mapping is a feature of the ABAP Runtime Environment (BC-ABA) in SAP that allows for the mapping of multiple tables to a single table. This feature allows for the creation of complex data structures that can be used to store and manipulate data. It also allows for the creation of relationships between tables, which can be used to create more efficient queries and data access. 
  
  How to use it: 
  To use multiple table mapping, you must first create a mapping table. This table will contain the names of the tables that you want to map together. Once the mapping table is created, you can then create relationships between the tables by defining foreign keys in each table. This will allow you to access data from multiple tables in a single query. 
  
  Tips & Tricks: 
  When creating a mapping table, it is important to ensure that all of the tables being mapped together have compatible data types. This will ensure that data can be accessed and manipulated correctly. Additionally, it is important to ensure that all of the foreign keys are properly defined in order to ensure that data can be accessed correctly.
