  Solution:
  
  Check Existing Addresses: Use transaction codes like BP (Business Partner) or XD03 (Display Customer) to check if the address number is already assigned to another entity.
  Use a Different Address Number: If the address number is indeed in use, you will need to select a different address number that is not currently assigned.
  Address Deletion: If the address is no longer needed, you may consider deleting the existing address (if permissible) to free up the address number.
  Data Consistency Check: If this issue arises after a data migration, perform a consistency check to ensure that there are no duplicate entries in the database.
