• What is the cause and solution for SAP error message /SCWM/MIGRATION120 - Storage bin &1 already exists; it will be overwritten ?

  The SAP error message /SCWM/MIGRATION120 Storage bin &1 already exists; it will be overwritten typically occurs during the migration process in the SAP Extended Warehouse Management (EWM) module. This error indicates that there is an attempt to create a storage bin that already exists in the system, and the system is warning that the existing storage bin will be overwritten.
  Cause:
  
  Duplicate Storage Bin: The primary cause of this error is that the storage bin you are trying to create or migrate already exists in the system. This can happen if the migration process is being run multiple times or if there are inconsistencies in the data being migrated.
  Data Migration Issues: If the data being imported or migrated contains duplicates or if the migration logic does not account for existing records, this error can occur.
  
  Solution:
  
  
  Check Existing Storage Bins: Before running the migration, check the existing storage bins in the system to ensure that the one you are trying to create does not already exist. You can do this by using transaction codes like /SCWM/LS01 or /SCWM/LS02 to view storage bin details.
  
  
  Modify Migration Data: If you find that the storage bin already exists, you may need to modify your migration data to either:
  
  Exclude the existing storage bins from the migration process.
  Update the existing storage bins instead of trying to create new ones.
  
  
  
  Use Overwrite Option: If overwriting the existing storage bin is acceptable, you can adjust the migration settings to allow for overwriting. However, be cautious with this approach as it may lead to loss of existing data associated with that storage bin.
  
  
  Data Cleanup: If there are unnecessary duplicates in your data, consider cleaning up the data before migration to avoid such conflicts.
  
  
  Consult Documentation: Review the SAP documentation related to the migration process for any specific guidelines or best practices that may help in resolving this issue.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM for managing storage bins and migration processes.
  SAP Notes: Check for any SAP Notes related to this error message for additional insights or patches that may address the issue.
  Testing: Always perform migration in a test environment before executing it in production to identify potential issues without impacting live data.
  
  By following these steps, you should be able to resolve the error and successfully complete your migration process in SAP EWM.
