  The SAP error message AU030 ("Enter a main asset number when using external number assignment") typically occurs when you are trying to create or manage an asset in the Asset Accounting (FI-AA) module, and the system requires a main asset number to be specified, but it has not been provided.
  Cause:
  This error arises when:
  
  You are using external number assignment for asset creation, which means that the system expects you to provide a specific asset number.
  The main asset number field is left blank or not filled in correctly during the asset creation process.
  
  Solution:
  To resolve the AU030 error, you can take the following steps:
  
  
  Provide a Main Asset Number:
  
  When creating or modifying an asset, ensure that you enter a valid main asset number in the appropriate field. This is typically done in the asset master record screen.
  
  
  
  Check Configuration:
  
  If you are consistently encountering this error, check the configuration settings for asset accounting in your SAP system. Ensure that the settings for external number assignment are correctly configured to allow for the entry of main asset numbers.
  
  
  
  Use Internal Number Assignment:
  
  If external number assignment is not a strict requirement, consider switching to internal number assignment. This way, the system will automatically generate the asset number for you, and you won't need to manually enter a main asset number.
  
  
  
  Review User Permissions:
  
  Ensure that the user has the necessary permissions to create or modify asset records. Sometimes, restrictions in user roles can lead to issues in data entry.
