ABAP: Validate Email Addresses Using CL_BCS_EMAIL_ADDRESS

Don’t write custom regex for email validation — SAP provides a standard class that validates against RFC 5322.

Using cl_bcs_email_address=>validate()

CLASS lcl_email DEFINITION CREATE PUBLIC.
  PUBLIC SECTION.
    CLASS-METHODS validate
      IMPORTING iv_email        TYPE string
      RETURNING VALUE(rv_valid) TYPE abap_boolean.
ENDCLASS.

CLASS lcl_email IMPLEMENTATION.
  METHOD validate.
    TRY.
        cl_bcs_email_address=>validate( iv_email ).
        rv_valid = abap_true.
      CATCH cx_address_exception.
        rv_valid = abap_false.
    ENDTRY.
  ENDMETHOD.
ENDCLASS.

Usage

IF lcl_email=>validate( 'user@example.com' ) = abap_true.
  " Valid email
ELSE.
  " Invalid email
ENDIF.

Test Cases

Email	Result
user@example.com	Valid
user.name+tag@domain.co	Valid
user@domain	Invalid (no TLD)
@domain.com	Invalid (no local part)
user@	Invalid
plaintext	Invalid

Why Use the Standard Class?

• Implements RFC 5322 — the actual email standard
• No maintenance — SAP keeps it up to date
• Handles edge cases that custom regex often misses (quoted strings, internationalized domains)
• Works in both on-premise and BTP ABAP Environment

One try-catch, one method call — clean and reliable.
