  Key Concepts: 
  A table cluster is a type of table in the SAP ABAP Dictionary. It is a collection of related tables that are stored together in the database. The tables in a cluster are linked together by a common key field, which is used to join the tables together. This allows for faster access to data and improved performance when querying multiple tables. 
  
  How to use it: 
  Table clusters can be created in the ABAP Dictionary by defining the common key field and the tables that should be included in the cluster. Once created, the table cluster can be used like any other table in SAP. Queries can be written to access data from multiple tables in the cluster at once, and data can be inserted or updated in all of the tables at once. 
  
  Tips & Tricks: 
  When creating a table cluster, it is important to consider which fields should be used as the common key field. This should be a field that is present in all of the tables and is not likely to change over time. It is also important to consider which tables should be included in the cluster, as this will affect performance when querying data from multiple tables.
