  Key Concepts: 
  A hashed table is a type of internal table in SAP that stores data in a hash structure. It is used to store and access data quickly and efficiently. The hash structure is based on a hashing algorithm, which assigns each record a unique key. This key is used to access the record quickly, without having to search through the entire table. 
  
  How to use it: 
  Hashed tables are used in the ABAP runtime environment of SAP. To create a hashed table, you must first define the table structure and then use the HASHED TABLE statement to create the table. You can then insert data into the table using the INSERT statement. To access data from the table, you can use the READ statement with the key of the record you want to access. 
  
  Tips & Tricks: 
  When creating a hashed table, it is important to choose an appropriate hashing algorithm for your data. Different algorithms have different performance characteristics, so it is important to choose one that will work best for your data set. Additionally, when inserting data into a hashed table, it is important to ensure that each record has a unique key so that it can be accessed quickly and efficiently.
