• What is the cause and solution for SAP error message BRAIN321 - InfoProvider &1 does not exist or was changed at runtime ?

  The SAP error message BRAIN321 indicates that the specified InfoProvider does not exist or has been modified during runtime. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when trying to access or query an InfoProvider that is either not available or has been altered in a way that the current query cannot process it.
  Causes:
  
  Non-Existent InfoProvider: The InfoProvider you are trying to access may not exist in the system. This could be due to a typo in the name or the InfoProvider being deleted.
  Runtime Changes: The InfoProvider may have been modified or restructured while a query is being executed. This can happen if there are ongoing changes in the data model or if the InfoProvider is being reloaded.
  Authorization Issues: The user executing the query may not have the necessary authorizations to access the InfoProvider.
  Transport Issues: If the InfoProvider was recently transported from another system, it may not have been activated properly in the target system.
  Data Source Issues: If the InfoProvider is based on a data source that is not available or has been changed, it can lead to this error.
  
  Solutions:

  Check for Runtime Changes: If the InfoProvider was modified, ensure that the changes are complete and that the InfoProvider is active. You may need to refresh or re-execute the query after the changes.
  Review Authorizations: Ensure that the user has the necessary authorizations to access the InfoProvider. You can check this in the user roles and authorizations.
