• Key Concepts: 
  A check field is a field in an ABAP Dictionary table that is used to check the validity of a value entered into another field. It is used to ensure that the value entered into the other field is valid and meets certain criteria. The check field can be used to check for specific values, ranges of values, or even a combination of values. 
  
  How to use it: 
  To use a check field, you must first define it in the ABAP Dictionary. This can be done by selecting the “Check Field” option from the “Fields” tab in the ABAP Dictionary. Once defined, you can then assign it to a field in the table. When a value is entered into the field, the check field will be used to validate it. If the value does not meet the criteria specified in the check field, an error message will be displayed. 
  
  Tips & Tricks:

This includes setting up the correct data type and length for the check field, as well as specifying any additional criteria that should be checked.
