• Key Concepts: 
  A table key is a set of fields in a database table that uniquely identifies each record in the table. It is used to ensure data integrity and to prevent duplicate entries. In SAP, a table key is defined in the ABAP Dictionary and consists of one or more fields that are marked as key fields. 
  
  How to use it: 
  Table keys are used to ensure that each record in a database table is unique. When creating a new record, the system checks if the combination of values for the key fields already exists in the table. If it does, the system will not allow the new record to be saved. 
  
  Tips & Tricks: 
  When defining a table key, it is important to consider which fields should be included in the key. The more fields that are included, the more unique each record will be. However, including too many fields can make it difficult to find records in the table. 
  
  Related Information: 
  Table keys are closely related to primary keys and foreign keys. A primary key is a field or set of fields that uniquely identifies each record in a database table. A foreign key is a field or set of fields that references a primary key in another table.
