• What is the cause and solution for SAP error message AM320 - Sequential number & already exists; entry in & ignored ?

  The SAP error message AM320 indicates that there is a duplicate entry for a sequential number in the Asset Accounting (FI-AA) module. This typically occurs when you are trying to create or modify an asset master record, and the system detects that the sequential number you are trying to use already exists in the database.
  Cause:
  
  Duplicate Sequential Number: The most common cause is that the sequential number you are trying to assign to an asset already exists in the system.
  Incorrect Configuration: There may be issues with the configuration of the number ranges for asset numbers, leading to overlaps or duplicates.
  Data Migration Issues: If data has been migrated from another system, there may be conflicts with existing records in SAP.
  
  Solution:
  
  
  Check Existing Entries: Verify the existing asset records to see if the sequential number you are trying to use is already assigned to another asset. You can do this by using transaction codes like AS03 (Display Asset) to look up the asset master records.
  
  
  Use a Different Sequential Number: If the number is already in use, you will need to select a different sequential number that does not conflict with existing records.
  
  
  Review Number Range Configuration: Check the configuration of the number ranges for asset accounting. You can do this using transaction code OAOA (Define Number Ranges for Assets). Ensure that the number ranges are set up correctly and that there are no overlaps.
  
  
  Data Cleanup: If the error is due to data migration, you may need to clean up the data to remove duplicates or adjust the sequential numbers accordingly.
  
  
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance related to your system configuration and setup.
