• What is the cause and solution for SAP error message FDT_EXPRESSIONS760 - Result data type does not match the table line type ?

  The SAP error message FDT_EXPRESSIONS760 indicates that there is a mismatch between the result data type of an expression and the expected line type of a table in your SAP application. This error typically occurs in the context of using expressions in the Field Data Tool (FDT) or when working with data transformation and mapping in SAP.
  Cause:
  
  Data Type Mismatch: The expression you are using is returning a data type that does not match the expected data type of the target table line. For example, if the target table expects a numeric value but the expression returns a string, this error will occur.
  Incorrect Mapping: If you are mapping fields from one structure to another, ensure that the data types of the source and target fields are compatible.
  Field Configuration: The configuration of the fields in the FDT might not align with the data types defined in the underlying database tables.
  
  Solution:
  
  Check Data Types: Review the data types of both the expression result and the target table line. Ensure that they are compatible. You may need to cast or convert the data type in your expression to match the expected type.
  Modify Expression: If necessary, modify the expression to ensure it returns the correct data type. For example, if you need to convert a string to a number, you can use conversion functions like CONVERT_TO_NUMBER.
  Review Field Mappings: Go through the field mappings in your FDT configuration to ensure that all mappings are correct and that the data types align.
  Debugging: Use debugging tools to trace the execution of the expression and identify where the mismatch occurs. This can help you pinpoint the exact location of the issue.
  Consult Documentation: Refer to SAP documentation or help resources for specific details on data types and expressions in the context of your version of SAP.
