• What is the cause and solution for SAP error message RSCRM_APPL021 - D-U-N-S number &2 already exists for business partner &1 ?

  The SAP error message RSCRM_APPL021 indicates that there is a conflict with the D-U-N-S (Data Universal Numbering System) number for a business partner in the system. Specifically, it means that the D-U-N-S number you are trying to assign to a business partner already exists for another business partner in the SAP system.
  Cause:
  
  Duplicate D-U-N-S Number: The primary cause of this error is that the D-U-N-S number you are trying to assign to a business partner is already associated with another business partner in the SAP system.
  Data Entry Error: There may have been a mistake in data entry, leading to the attempt to assign the same D-U-N-S number to multiple business partners.
  Data Migration Issues: If data was migrated from another system, there may be duplicates in the D-U-N-S numbers.
  
  Solution:
  
  
  Check Existing Business Partners: 
  
  Use transaction codes like BP (Business Partner) to search for the existing business partners that have the same D-U-N-S number.
  You can also use the D-U-N-S number to search for the business partner directly.
  
  
  
  Assign a Unique D-U-N-S Number:
  
  If the D-U-N-S number is indeed already in use, you will need to assign a different, unique D-U-N-S number to the business partner you are trying to create or modify.
  
  
  
  Data Cleanup:
  
  If you find that there are duplicates due to data migration or entry errors, you may need to clean up the data. This could involve merging business partners or correcting the D-U-N-S numbers.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidelines on managing business partners and D-U-N-S numbers.
  
  
  
  Custom Development:
  
  If your organization has specific requirements regarding D-U-N-S numbers, consider discussing with your SAP development team to implement custom checks or processes to handle D-U-N-S assignments more effectively.
