• What is the cause and solution for SAP error message CAWUSL145 - Aggregate function 'average' only possible for numeric fields ?

  The SAP error message CAWUSL145 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.
  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 aggregate function. 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 the average calculation.
  
  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 to a numeric type before performing the average calculation.
  Check Data Model: Review the data model to ensure that the fields are correctly defined and that the data types align with the intended calculations.
