  The SAP error message BRAIN303 indicates that there is an issue with the aggregation level of an InfoProvider in SAP BW (Business Warehouse). This error typically arises when you are trying to execute a query or perform an operation that requires a simpler aggregation level than what is currently defined for the InfoProvider.
  Cause:
  The error occurs due to the following reasons:
  
  Complex Aggregation Level: The InfoProvider has a complex aggregation level that cannot be processed in the context of the query or operation you are trying to execute.
  Incompatible Query: The query you are trying to run may not be compatible with the defined aggregation levels of the InfoProvider.
