• What is the cause and solution for SAP error message FDT_EXPRESSIONS757 - For aggregation operation, result should always be numeric ?

  The SAP error message FDT_EXPRESSIONS757 indicates that there is an issue with an aggregation operation in your SAP system, specifically that the result of the aggregation should be numeric, but it is not. This error typically arises in the context of data processing, such as in SAP Analytics Cloud, SAP BW, or other SAP applications that involve data modeling and calculations.
  Cause:
  
  Non-Numeric Data: The most common cause of this error is that the data being aggregated includes non-numeric values (e.g., text, dates, or other non-numeric types).
  Data Type Mismatch: The fields being used in the aggregation may have incompatible data types, leading to an inability to perform the aggregation correctly.
  Incorrect Formula: If you are using a custom formula or expression for aggregation, it may be incorrectly defined, leading to non-numeric results.
  Null or Blank Values: If the dataset contains null or blank values, it may cause the aggregation to fail if not handled properly.
  
  Solution:
  
  Check Data Types: Ensure that all fields involved in the aggregation are of a numeric data type. You can do this by reviewing the data model or the underlying data source.
  Data Cleansing: Clean the data to remove or convert non-numeric values. This may involve filtering out rows with non-numeric entries or converting data types where applicable.
  Modify Aggregation Logic: If you are using a custom formula, review and modify it to ensure that it only processes numeric values. You may need to use functions to handle non-numeric cases (e.g., using IF statements to check for numeric values).
  Handle Null Values: Implement logic to handle null or blank values appropriately. This could involve using functions like COALESCE to replace nulls with a default numeric value.
  Testing: After making changes, test the aggregation operation again to ensure that it works as expected without triggering the error.
  
  Related Information:
  
  Documentation: Refer to SAP documentation for the specific application you are using (e.g., SAP BW, SAP Analytics Cloud) for more details on data types and aggregation functions.

  Debugging Tools: Use debugging tools available in your SAP environment to trace the data flow and identify where the non-numeric values are being introduced.
