Data Validation in RAP: Ensuring Clean Phone Numbers & Emails

In modern applications, ensuring data integrity is crucial, and phone number and email validation play a vital role in keeping records accurate. When working with RESTful Application Programming (RAP) in SAP, enforcing these validation rules at the application level prevents erroneous data entry and enhances reliability.

A valid email must:

Follow the correct format: username@domain.com
Include @ and a valid domain (e.g., .com, .org, .de)
