• Key Concepts: 
  Primary key integrity is a feature of the ABAP Dictionary in SAP that ensures that each record in a database table has a unique identifier. This identifier, known as the primary key, is used to identify and access records in the table. Primary key integrity ensures that no two records have the same primary key value. 
  
  How to use it: 
  When creating a database table in the ABAP Dictionary, you can define a primary key for the table. This primary key can be composed of one or more fields from the table. When you define a primary key, SAP automatically creates an index for it and enforces primary key integrity. This means that when you add new records to the table, SAP will check to make sure that the primary key value is unique before allowing the record to be added. 
  
  Tips & Tricks: 
  When defining a primary key for a database table, it is important to choose fields that are unlikely to change over time. This will ensure that the primary key values remain unique and that records can be easily identified and accessed.
