• What is the cause and solution for SAP error message UGMD8126 - RFC conversion exits are not supported ?

  The SAP error message UGMD8126, which states "RFC conversion exits are not supported," typically occurs when there is an issue with the conversion of data types during Remote Function Call (RFC) communication between SAP systems. This error indicates that the system is trying to use a conversion exit that is not supported in the context of RFC calls.
  Cause:
  
  
  Conversion Exits: In SAP, conversion exits are used to format data (e.g., date formats, currency formats) when transferring data between different fields. However, these conversion exits are not supported in RFC calls because they require a specific context that is not available in the remote environment.
  
  
  Data Type Mismatch: The error can also occur if there is a mismatch in the data types between the calling and called systems, especially if one system is trying to use a conversion exit that the other does not recognize.
  
  
  Incorrect Function Module: If the function module being called is not designed to handle the data types being passed, it can lead to this error.
  
  
  Solution:
  
  
  Remove Conversion Exits: Review the code where the RFC call is made and ensure that any conversion exits are removed or replaced with standard data types that do not require conversion. For example, instead of using a conversion exit for a date, use a standard date format.
  
  
  Check Data Types: Ensure that the data types being passed in the RFC call match the expected data types in the called function module. This may involve adjusting the data structure or using appropriate data types.
  
  
  Modify Function Module: If you have control over the function module being called, consider modifying it to handle the data types correctly without relying on conversion exits.
  
  
  Testing: After making changes, thoroughly test the RFC call to ensure that the error is resolved and that data is being transferred correctly.

  RFC (Remote Function Call): A protocol used in SAP to enable communication between different SAP systems or between SAP and non-SAP systems.
  Conversion Exits: Functions in SAP that allow for the conversion of data formats, such as converting a date from one format to another.
  Function Modules: Reusable pieces of code in SAP that can be called from other programs or function modules, often used in RFC calls.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult SAP documentation or reach out to SAP support for further assistance.
