• What is the cause and solution for SAP error message FDT_EXPRESSIONS055 - Data conversion conflict; &1 to &2 (position &3) ?

  The SAP error message FDT_EXPRESSIONS055 indicates a data conversion conflict when trying to convert data from one type to another. The message typically includes placeholders for the source data type (&1), the target data type (&2), and the position in the data where the conflict occurred (&3). This error often arises in scenarios involving data transformation, such as when using SAP Data Services, SAP S/4HANA, or other data processing tools.
  Cause:
  The error can occur due to several reasons:
  
  Incompatible Data Types: The source data type is not compatible with the target data type. For example, trying to convert a string that contains non-numeric characters into a numeric type.
  Data Format Issues: The format of the data being converted does not match the expected format for the target type. For instance, date formats or decimal separators may differ.
  Null or Empty Values: Attempting to convert null or empty values can also lead to this error, especially if the target type does not allow nulls.
  Overflow or Underflow: The value being converted exceeds the range of the target data type.
  
  Solution:
  To resolve the FDT_EXPRESSIONS055 error, consider the following steps:
  
  Check Data Types: Verify that the source and target data types are compatible. Ensure that the data being converted can be represented in the target type.
  Data Cleansing: Clean the source data to ensure it meets the expected format. For example, remove non-numeric characters from strings before converting to numeric types.
  Format Consistency: Ensure that date formats and numeric formats (like decimal separators) are consistent with what the target type expects.
  Handle Nulls: Implement logic to handle null or empty values appropriately. You may need to provide default values or skip conversion for such cases.
  Check for Overflow/Underflow: Ensure that the values being converted do not exceed the limits of the target data type.
  
  Related Information:
  
  Debugging: Use debugging tools in SAP to trace the data flow and identify the exact point of failure.
  Documentation: Refer to SAP documentation for specific data types and their conversion rules.
  Data Services: If using SAP Data Services, check the transformation logic and ensure that the mappings are correctly defined.
  Community Forums: Consider checking SAP community forums or support channels for similar issues and solutions shared by other users.
  
  By following these steps, you should be able to identify the root cause of the data conversion conflict and implement a suitable solution.
