• What is the cause and solution for SAP error message VN123 - No mail user found for personnel number & ?

  SAP Error Message:
  
  VN123 No mail user found for personnel number &
  
  Cause:
  This error occurs when the SAP system tries to send an email notification or workflow message to a personnel number (employee) but cannot find an associated email address or mail user in the system for that personnel number.
  In other words, the system expects that the employee (personnel number) has a valid email address maintained in the SAP HR master data or in the communication system, but it is missing or not properly linked.
  
  Detailed Explanation:
  
  The personnel number is used to identify the employee in SAP HR.
  For sending emails (e.g., workflow notifications, alerts), SAP looks up the employee's email address.
  The email address is typically maintained in the Communication infotype (IT0105) or in the User Master Record (SU01) if the employee has a SAP user.
  If no email address is found, the system cannot send the mail and throws this error.
  
  
  Solution:
  
  
  Check and Maintain Email Address in HR Master Data:
  
  Go to transaction PA30 (Maintain HR Master Data).
  Enter the personnel number.
  Select infotype 0105 (Communication).
  Check if the email address is maintained under the subtype Internet or E-mail.
  If missing, maintain the correct email address and save.
  
  
  
  Check SAP User Master Record:
  
  If the employee has a SAP user, check transaction SU01.
  Enter the user ID linked to the personnel number.
  Go to the Address tab and verify the email address.
  Maintain if missing.
  
  
  
  Check Integration with SAP Business Workplace or Workflow:
  
  Sometimes, the email address is derived from the SAP user linked to the personnel number.
  Ensure that the personnel number is correctly linked to a SAP user.
  Use transaction SU01 or PPOSE (Organizational Management) to verify the link.
  
  
  
  Check if the Employee is Active:
  
  If the employee is inactive or has left the company, the email might be removed.
  Confirm the status of the employee in infotype 0000 (Actions) or 0001 (Organizational Assignment).
  
  
  
  Check SMTP Configuration:
  
  Ensure that the SAP system is configured properly to send emails.
  Transaction SCOT is used to configure and monitor email sending.
  However, this error is specifically about missing email address, so SMTP config is less likely the cause.
  
  
  
  
  Related Information:
  
  Infotype 0105 (Communication): Stores communication details including email addresses.
  Transaction PA30: Maintain HR master data.
  Transaction SU01: Maintain SAP user master data.
  Transaction SCOT: SAPconnect administration for email.
  Workflow Notifications: Often require email addresses to notify employees.
  Personnel Number to User Mapping: Sometimes maintained in custom tables or via standard HR user mapping.
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  No email address found for personnel number in HR master data or SAP user record.

  Transactions
  PA30, SU01, SCOT, PPOSE
  
  
  Additional
  Ensure employee is active and email sending is configured properly.
