  The SAP error message LRM012, which states "Object with business key '&1' already exists," typically occurs in the context of SAP Master Data Governance (MDG) or when working with business objects that require unique identifiers (business keys). This error indicates that you are trying to create or register an object (such as a material, vendor, or customer) that already exists in the system with the same business key.
  Cause:

  Solution:
  
  Check for Existing Object: Before creating a new object, check the database or the relevant application to see if an object with the same business key already exists. You can use transaction codes like SE16 or SE11 to query the relevant tables.
  Use a Different Business Key: If you are sure that the object you are trying to create is new, consider using a different business key that does not conflict with existing entries.
  Data Cleansing: If you are migrating data, ensure that the data being imported is cleansed and does not contain duplicates. This may involve deduplication processes before the import.
  Review Configuration: If the issue persists, review the configuration of the business object in SAP to ensure that the uniqueness constraints are correctly set up.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the business object you are working with.
