• What is the cause and solution for SAP error message BRAIN058 - Cannot calculate character key figures ?

  The SAP error message BRAIN058: "Cannot calculate character key figures" typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an attempt to perform calculations on key figures that are defined as character data types. Character key figures are not suitable for mathematical operations, which leads to this error.
  Causes:
  
  Data Type Mismatch: The key figure you are trying to calculate is defined as a character type (CHAR) instead of a numeric type (NUMC, DEC, etc.).
  Incorrect Query Design: The query may be incorrectly designed to include character key figures in calculations or aggregations.
  Data Source Issues: The underlying data source may have character fields that are being treated as key figures in the query.
  Aggregation Issues: Attempting to aggregate or perform operations on character fields that do not support such operations.
  
  Solutions:
  
  
  Check Key Figure Definitions: Review the definitions of the key figures in the InfoObject and ensure that they are defined with the correct data type. If a key figure is meant to be numeric, it should be defined as such.
  
  
  Modify the Query: If the query is attempting to perform calculations on character key figures, modify the query to exclude these key figures from calculations. Ensure that only numeric key figures are included in calculations.
  
  
  Data Source Review: Check the underlying data source (e.g., InfoProvider, DSO, etc.) to ensure that the data types are correctly defined and that character fields are not being misused as key figures.
  
  
  Use of Calculated Key Figures: If you need to perform calculations involving character data, consider creating a calculated key figure that converts the character data to a numeric format if applicable. However, this is only feasible if the character data can logically be converted to a number.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling key figures and data types in BW/BI.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered and resolved similar issues.
  Testing: After making changes, test the query to ensure that the error is resolved and that the calculations are performed correctly.
  
  By addressing the root cause of the error and ensuring that the data types are correctly defined and used, you should be able to resolve the BRAIN058 error in SAP.
