• What is the cause and solution for SAP error message AU026 - You cannot specify main asset number with internal number assignment ?

  The SAP error message AU026 ("You cannot specify main asset number with internal number assignment") typically occurs in the Asset Accounting (FI-AA) module when there is an attempt to manually assign a main asset number while the system is set to use internal number assignment for asset numbers.
  Cause:
  The error arises because:
  
  The asset master record is configured to use internal number assignment, which means that the system automatically generates asset numbers.
  When trying to create or modify an asset, the user is attempting to specify a main asset number manually, which is not allowed under the internal number assignment setting.
  
  Solution:
  To resolve this error, you can take one of the following approaches:
  
  
  Use Internal Number Assignment:
  
  If the asset is set to use internal number assignment, do not specify a main asset number. Allow the system to generate the asset number automatically.
  
  
  
  Change to External Number Assignment:
  
  If you need to specify a main asset number, you can change the asset number assignment method to external. This can be done in the configuration settings:
  
  Go to the SAP Customizing Implementation Guide (SPRO).
  Navigate to Financial Accounting (New) > Asset Accounting > Master Data > Define Number Ranges for Assets.
  Here, you can configure the number range settings to allow for external number assignment.
  
  
  
  
  
  Check Asset Master Data:
  
  Review the asset master data settings to ensure that the configuration aligns with your business requirements regarding number assignment.

  Documentation:
  
  Refer to SAP Help documentation for Asset Accounting for more detailed information on asset number assignment and configuration.
  
  
  
  User Roles and Authorizations:
  
  Ensure that the user has the necessary authorizations to create or modify asset records, as this can also lead to errors if permissions are insufficient.
  
  
  
  By following these steps, you should be able to resolve the AU026 error and proceed with your asset accounting tasks in SAP.
