  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:
