• What is the cause and solution for SAP error message FDT_EXPRESSIONS781 - Source object conversion into target (position &1) is data-dependent ?

  The SAP error message FDT_EXPRESSIONS781 indicates that there is an issue with the conversion of a source object into a target object during a data transformation process. This error typically arises in the context of SAP Data Services or SAP Financial Data Transformation (FDT) when the conversion is dependent on the data being processed.
  Cause:
  The error occurs when the conversion from the source data type to the target data type cannot be performed because it is dependent on the actual data values. This can happen for several reasons, including:
  
  Data Type Mismatch: The source and target data types are incompatible, and the conversion logic cannot handle the specific data values.
  Null or Invalid Values: The source data may contain null or invalid values that cannot be converted to the target type.
  Complex Expressions: If the transformation involves complex expressions or calculations, the result may vary based on the input data, leading to conversion issues.
  Conditional Logic: If the conversion logic includes conditions that depend on the data, it may fail if the conditions are not met.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  Check Data Types: Ensure that the source and target data types are compatible. Review the data types in the transformation logic and make necessary adjustments.
  Validate Input Data: Check the source data for null or invalid values. You may need to clean or preprocess the data to ensure it meets the requirements for conversion.
  Simplify Expressions: If the transformation involves complex expressions, consider simplifying them or breaking them down into smaller, manageable parts.
  Add Error Handling: Implement error handling in your transformation logic to manage cases where conversion may fail. This could involve using default values or conditional checks.
  Test with Sample Data: Run tests with different sets of sample data to identify specific cases that trigger the error. This can help you pinpoint the exact cause and make necessary adjustments.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidance on data transformations and error handling in SAP Data Services or FDT.
  SAP Community: Engage with the SAP Community forums to seek advice from other users who may have encountered similar issues.
  Debugging Tools: Utilize debugging tools available in SAP to trace the data flow and identify where the conversion is failing.
  
  By following these steps, you should be able to diagnose and resolve the FDT_EXPRESSIONS781 error effectively.
