• What is the cause and solution for SAP error message FDT_EXPRESSIONS620 - No aggregation should be set for this mode ?

  The SAP error message FDT_EXPRESSIONS620 ("No aggregation should be set for this mode") typically occurs in the context of SAP's Flexible Data Import (FDI) or when working with expressions in SAP Analytics Cloud (SAC) or similar environments where data modeling and aggregation are involved.
  Cause:
  This error usually arises when you attempt to set an aggregation method (like SUM, AVG, etc.) on a data field that is not compatible with aggregation in the current context. This can happen in scenarios such as:
  
  Incompatible Data Types: The data type of the field you are trying to aggregate does not support aggregation (e.g., text fields).
  Incorrect Mode: The mode of the expression or calculation you are trying to perform does not allow for aggregation. For example, if you are working with a dimension that is meant to be treated as a categorical variable rather than a numerical one.
  Configuration Issues: There may be a misconfiguration in the data model or the way the expressions are defined.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Data Types: Ensure that the fields you are trying to aggregate are of a numerical type. If they are not, you may need to convert them or use a different field that is suitable for aggregation.
  
  
  Review Expression Mode: Verify the mode of the expression you are using. If the expression is meant to be a categorical or descriptive measure, do not apply aggregation functions to it.
  
  
  Adjust Data Model: If you are working within a data model, check the configuration of the model to ensure that the fields are set up correctly for aggregation. This may involve adjusting the properties of the fields in the model.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific tool or module you are using (e.g., SAP Analytics Cloud, SAP BW, etc.) to understand the rules around aggregation and expressions.
  
  
  Testing: After making adjustments, test the expression or calculation again to see if the error persists.
