• What is the cause and solution for SAP error message AY303 - Changing indicators "Manage AuC", "AuC per source struct..." not allowed ?

  The SAP error message AY303, which states "Changing indicators 'Manage AuC', 'AuC per source struct...' not allowed," typically occurs in the context of Asset Accounting (FI-AA) when there is an attempt to change certain indicators related to Asset Under Construction (AuC) settings in a way that is not permitted by the system.
  Cause:
  
  
  Configuration Restrictions: The error usually arises when there is an attempt to change the configuration settings for AuC management after certain transactions have already been executed. For example, if assets have already been created or transactions have been posted, changing the indicators related to AuC management is restricted.
  
  
  Data Consistency: SAP enforces data consistency and integrity, which means that once certain settings are established and transactions are processed, changing those settings can lead to inconsistencies in the data.
  
  
  Authorization Issues: Sometimes, the error may also be related to insufficient authorization to make changes to the configuration settings.
  
  
  Solution:
  
  
  Review Configuration: Check the configuration settings in the Asset Accounting module. Ensure that the indicators for "Manage AuC" and "AuC per source struct" are set correctly according to your business requirements before any transactions are posted.
  
  
  Avoid Changes After Posting: If transactions have already been posted, avoid changing these indicators. Instead, if a change is necessary, consider creating a new company code or a new asset class with the desired settings.
  
  
  Consult Documentation: Refer to SAP documentation or the SAP Help Portal for detailed information on the specific indicators and their implications.
  
  
  Authorization Check: Ensure that you have the necessary authorizations to make changes to the configuration settings. If not, contact your SAP security administrator.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this issue. Sometimes, there are specific patches or updates that can resolve configuration-related issues.
  
  
  Testing in Development: If you need to make changes, consider testing them in a development or sandbox environment first to ensure that they do not lead to errors in the production environment.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like OAOA (for Asset Accounting configuration) to review and adjust settings.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  Consulting SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance.
