• What is the cause and solution for SAP error message CM_EHHSS_INC_COMMON247 - Multiple entries exist for e-mail address &1 ?

  The SAP error message CM_EHHSS_INC_COMMON247 indicates that there are multiple entries in the system for a specific email address. This typically occurs in scenarios where the system expects a unique email address for a user or a contact, but finds duplicates instead.
  Cause:
  
  Duplicate Entries: The primary cause of this error is that the email address in question is associated with more than one record in the database. This could happen due to:
  
  Data entry errors where the same email address was entered for multiple users or contacts.
  Migration of data from another system that did not enforce unique constraints on email addresses.
  Manual updates or imports that did not check for existing records.
  
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicate Entries:
  
  Use transaction codes like SE16 or SE11 to access the relevant database tables (e.g., USR21 for user master records) and search for the email address in question.
  Run a query to find all records that contain the duplicate email address.
  
  
  
  Review and Clean Up Data:
  
  Once you have identified the duplicate entries, review them to determine which records are valid and which can be deleted or merged.
  If necessary, update the records to ensure that each email address is unique. This may involve changing the email address for some users or contacts.
  
  
  
  Implement Data Validation:
  
  To prevent this issue from occurring in the future, consider implementing data validation rules that enforce unique email addresses at the point of entry.
  This can be done through user exits, BAdIs, or custom validation logic in your SAP system.
