What is Pattern-Matching Validation used for?

Pattern-Matching Validation enables a user to input a specific string of characters to confirm if they are present in the data string. For instance, a user could enter the pattern 17V which is used in DI formats to identify the manufacturer's Enterprise Identifier. If the characters 17V are present in the code, the reader will signal a pass for validation for that code. If the characters are not present, the reader will signal a failure for validation.

You must use a Regular Expression as pattern for pattern validation.
