For hashed tables, the primary key is a hash key, for sorted tables the primary key is a sorted key. In both cases, it is an efficient method to access the table using the primary key. The key fields of these tables are read-only when you access individual cells. Standard tables also have a primary key, however the corresponding access method is not optimized and the key fields are not read-only.

• Key Concepts: 
  A primary table key is a unique identifier for a record in an SAP table. It is used to identify and access the data stored in the table. The primary table key consists of one or more fields that are combined to form a unique value. In the ABAP Runtime Environment, the primary table key is used to access data from the database. 
  
  How to use it: 
  The primary table key is used to access data from the database in the ABAP Runtime Environment. To access a record in an SAP table, you must specify the primary table key. This can be done by using the SELECT statement in ABAP. The SELECT statement requires you to specify the fields that make up the primary table key. 
  
  Tips & Tricks: 
  When specifying the fields that make up the primary table key, it is important to ensure that they are all specified correctly. If any of the fields are incorrect, then the record will not be found in the database. Additionally, it is important to ensure that all of the fields are specified in the correct order.
