• Key Concepts: 
  A check table is a type of table in the SAP ABAP Dictionary that is used to store valid values for a field. It is used to ensure that only valid values are entered into the system. The check table is linked to a field in the database table and the values stored in the check table are compared with the values entered into the field. If the value does not match, an error message is displayed.
  
  How to use it: 
  To use a check table, first create a database table and add a field to it. Then create a check table in the ABAP Dictionary and link it to the field in the database table. Finally, enter valid values into the check table and save it. When users enter data into the field, they will be prompted with an error message if they enter an invalid value.
  
  Tips & Tricks: 
  When creating a check table, make sure that all of the valid values are entered into it. This will ensure that only valid values are accepted by the system. Additionally, make sure that all of the fields in the check table are properly linked to their corresponding fields in the database table. This will ensure that all of the data is properly validated.
