• What is the cause and solution for SAP error message FDT_EXPRESSIONS204 - Units are unequal (&1,&2) and implicit conversion is turned off ?

  The SAP error message FDT_EXPRESSIONS204 indicates that there is a mismatch in units of measurement in a calculation or expression, and implicit conversion between these units is not allowed. This typically occurs in scenarios where you are working with different units that cannot be automatically converted by the system.
  Cause:
  
  Unit Mismatch: The error arises when you are trying to perform operations (like addition, subtraction, etc.) on two values that have different units (e.g., meters and kilometers).
  Implicit Conversion Disabled: The system is configured to not allow automatic conversion between these units, which means you need to handle the conversion explicitly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Units: Review the units of the values involved in the expression. Ensure that they are compatible for the operation you are trying to perform.
  
  
  Explicit Conversion: If the units are different, you need to convert one of the values to match the other. This can be done using appropriate conversion functions or by manually converting the units in your expression.
  
  
  Modify Configuration: If it is appropriate for your business logic, you can consider enabling implicit conversion for units in the system settings. However, this should be done with caution, as it may lead to unintended consequences if not managed properly.
  
  
  Debugging: If you are unsure where the error is occurring, you can use debugging tools in SAP to trace the execution and identify the specific line or operation causing the issue.
  
  
  Related Information:
  
  Unit of Measure (UoM): Understand the units of measure used in your SAP system. Familiarize yourself with the conversion factors between different units.
  SAP Documentation: Refer to SAP Help documentation for more details on handling units of measure and expressions in your specific version of SAP.
  Custom Code Review: If the error is occurring in custom code (e.g., ABAP), review the code to ensure that unit conversions are handled correctly.
  
  By following these steps, you should be able to resolve the FDT_EXPRESSIONS204 error and ensure that your calculations are performed correctly with compatible units.
