• What is the cause and solution for SAP error message BRAIN344 - Char. &1 is not a time char.; exception aggregation &2 is not possible ?

  The SAP error message BRAIN344 indicates that there is an issue with the characteristics being used in a query or report, specifically related to time characteristics and exception aggregation. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Incorrect Characteristic Type: The error occurs when a characteristic that is not defined as a time characteristic is being used in a context where a time characteristic is required. For example, if you are trying to perform an aggregation that is only valid for time characteristics (like year, month, day) on a non-time characteristic, this error will be triggered.
  
  
  Exception Aggregation Misconfiguration: The exception aggregation specified in the query or report is not compatible with the characteristic being used. Exception aggregations are specific types of calculations that can only be performed on certain types of data.
  
  
  Solution:
  
  
  Check Characteristic Definition: Verify the definition of the characteristic &1 in the InfoObject. Ensure that it is indeed a time characteristic if you intend to use it as such. If it is not, you may need to adjust your query or report to use a valid time characteristic.
  
  
  Review Query Design: Go through the query design in the BEx Query Designer or the relevant reporting tool. Ensure that the exception aggregation &2 is appropriate for the characteristics being used. If the aggregation is not suitable, consider changing it or using a different characteristic that aligns with the aggregation type.
  
  
  Modify Aggregation Logic: If you need to perform a specific aggregation that is not supported for the current characteristic, you may need to redesign the logic of your query or report. This could involve using a different characteristic or changing the way data is aggregated.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on exception aggregations and the characteristics that can be used with them. This can provide insights into what types of characteristics are valid for specific aggregations.
  
  
  Related Information:
  
  SAP BW/BI Documentation: Look for specific documentation related to the characteristics and exception aggregations in SAP BW/BI. This can provide detailed information on how to configure and use these features correctly.
  SAP Community Forums: Engaging with the SAP community can provide additional insights and solutions from other users who may have encountered similar issues.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide patches or updates that could resolve the issue.
  
  By following these steps, you should be able to identify the root cause of the BRAIN344 error and implement a suitable solution.
