• What is the cause and solution for SAP error message CM_EHFND_FW_CALC_ENG136 - Usage of "&1" not aggregated in equation "&2 = &3" is not permitted ?

  The SAP error message CM_EHFND_FW_CALC_ENG136 indicates that there is an issue with the usage of a specific field or variable in a calculation equation within the SAP system. The message states that the usage of the specified field (represented by &1) is not aggregated in the equation defined by &2 = &3. This typically occurs in the context of calculations in SAP applications, particularly in the areas of analytics, reporting, or data modeling.
  Cause:
  
  Non-Aggregated Field: The field being used in the equation is not aggregated, which means that it is being treated as a single value rather than a summary or total value.

  Incorrect Calculation Logic: The logic defined in the calculation might be incorrect or not aligned with the expected aggregation rules of the system.
  Data Model Issues: There may be issues with the underlying data model or the way the data is structured, leading to this error when trying to perform calculations.
  
  Solution:
  
  Check Aggregation: Review the calculation logic and ensure that all fields used in the equation are properly aggregated. You may need to use functions like SUM, AVG, COUNT, etc., to aggregate the values appropriately.
  Modify Calculation Logic: If the logic is incorrect, modify it to ensure that it adheres to the aggregation rules. This may involve changing the way the equation is structured or the fields that are being used.
  Review Data Model: Check the data model to ensure that the fields being used are correctly defined and that their data types and aggregation settings are appropriate for the calculations being performed.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the calculation framework and aggregation rules relevant to your version of SAP.
  Testing: After making changes, test the calculation to ensure that the error is resolved and that the results are as expected.
