• What is the cause and solution for SAP error message FDT_EXPRESSIONS637 - Result data object in aggregation mode should be an element ?

  The SAP error message FDT_EXPRESSIONS637 indicates that there is an issue with the configuration of a data object in an aggregation context. Specifically, it suggests that the result data object being used in an aggregation mode should be defined as an element rather than a structure or a table.
  Cause:
  This error typically arises in the context of using the SAP Fiori Design Time (FDT) or when working with expressions in SAP applications. The root cause is usually one of the following:
  
  
  Incorrect Data Object Type: The data object you are trying to use in an aggregation function (like SUM, AVG, etc.) is not defined as a single element (scalar value) but rather as a complex type (like a structure or a table).
  
  
  Misconfiguration in Expression: The expression or formula you are using may be incorrectly set up to reference a data object that is not suitable for aggregation.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Object Definition: Ensure that the data object you are trying to aggregate is defined as a scalar value (element) in your data model. If it is a structure or a table, you will need to adjust your data model accordingly.
  
  
  Modify the Expression: If you are using an expression in your application, review the expression to ensure that it references the correct data object. Make sure that the data object being aggregated is indeed an element.
  
  
  Review Aggregation Logic: If you are using a custom aggregation logic, ensure that it is correctly implemented and that it only operates on elements.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the requirements for data objects in aggregation contexts.
  
  
  Testing: After making the necessary changes, test the application to ensure that the error is resolved and that the aggregation works as expected.
