• What is the cause and solution for SAP error message WUSL145 - Aggregate function 'average' only possible for numeric fields ?

  The SAP error message WUSL145 indicates that there is an attempt to use the aggregate function 'average' on a field that is not numeric. This error typically occurs in the context of reporting or data analysis within SAP systems, such as SAP BW (Business Warehouse) or SAP HANA, where aggregate functions are applied to data fields.
  Cause:
  
  Non-Numeric Field: The field you are trying to calculate the average for is of a non-numeric data type (e.g., character, string, date).
  Data Type Mismatch: There may be a mismatch in the expected data type for the field being aggregated. For example, if the field is defined as a string in the data model, the average function cannot be applied.
  Incorrect Query Design: The query or report may be incorrectly designed, leading to the selection of inappropriate fields for aggregation.
  
  Solution:
  
  Check Field Data Type: Verify the data type of the field you are trying to average. Ensure that it is a numeric type (e.g., integer, decimal).
  Modify Query/Report: If the field is indeed non-numeric, you will need to either:
  
  Remove the average calculation from the query/report.
  Replace the field with a numeric field that makes sense for averaging.
  
  
  Data Transformation: If you need to average a field that is stored as a string (e.g., numbers stored as text), consider transforming the data type in the data model or during the ETL (Extract, Transform, Load) process to ensure it is numeric.
  Use Alternative Functions: If averaging is not applicable, consider using other aggregate functions that are suitable for the data type of the field.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on aggregate functions and data types.
  Data Modeling: Review the data model to ensure that fields are correctly defined and that numeric fields are used where necessary.
  Query Designer: If using SAP Query Designer or similar tools, ensure that the fields selected for aggregation are appropriate for the functions being applied.
  
  By addressing the data type issue and ensuring that the correct fields are used in your queries or reports, you should be able to resolve the WUSL145 error.
