• What is the cause and solution for SAP error message EM456 - Migration object &1 is referenced from companies &2 and &3 ?

  The SAP error message EM456 indicates that a migration object is being referenced by multiple companies, which can create issues during the migration process. This typically occurs in the context of data migration activities, such as when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error arises when:
  
  A migration object (like a customer, vendor, or material) is linked to more than one company code or entity in the system.
  The migration process expects that each migration object should be unique to a single company code, but the object is found in multiple company codes.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Migration Object: Check the migration object referenced in the error message (indicated by &1) and the companies (indicated by &2 and &3) that are causing the conflict.
  
  
  Review Data: Examine the data for the migration object in the respective company codes. You may need to look into the relevant tables or use transaction codes like SE16 or SE11 to analyze the data.
  
  
  Decide on the Migration Strategy:
  
  If the object should only exist in one company code, you may need to delete or adjust the references in the other company codes.
  If the object needs to exist in multiple company codes, consider creating separate entries for each company code in the migration data.
  
  
  
  Adjust Migration Data: Modify your migration data file (e.g., CSV, Excel) to ensure that each migration object is only associated with the intended company code.
  
  
  Re-run the Migration: After making the necessary adjustments, re-run the migration process to see if the error is resolved.
