  The SAP error message DDLS427 indicates that there is an issue with the use of the DECFLOAT data type, specifically regarding the scale of the DECFLOAT type in a return parameter. This error typically arises when you are trying to define or use a return parameter in a function module or method that has a DECFLOAT type with a scale that is not supported.
  Cause:
  
  Unsupported Scale: The DECFLOAT data type in SAP has specific limitations regarding the scale (the number of digits to the right of the decimal point). If the scale specified exceeds the allowed limits, this error will occur.

  Check Scale Definition: Review the definition of the DECFLOAT parameter in your function module or method. Ensure that the scale is within the supported range. The DECFLOAT type typically supports a scale of up to 34.
  Modify Data Type: If the scale is not supported, consider changing the data type of the return parameter to a different numeric type that meets your requirements, such as DECIMAL or FLOAT, depending on your precision needs.
  Update Function Module/Method: If you are developing or modifying a function module or method, ensure that the return parameter is defined correctly and that the data types used are compatible with the expected input and output.
  Check SAP Notes: Look for any relevant SAP Notes that might address this issue. Sometimes, there are known issues or patches that can resolve specific problems related to data types.
  Testing: After making changes, thoroughly test the function module or method to ensure that it behaves as expected and that the error does not recur.
