• What is the cause and solution for SAP error message FS_BP_PROXY021 - Function &1 is not supported remotely ?

  The SAP error message FS_BP_PROXY021, which states "Function &1 is not supported remotely," typically occurs when a function module or method is being called in a remote context (such as through a remote function call (RFC) or web service) that is not designed to be executed in that manner. This can happen in various scenarios, particularly when dealing with Business Partner (BP) functions in SAP.
  Cause:
  
  
  Function Module Restrictions: The function module or method you are trying to call is not designed to be executed remotely. Some functions are intended for local execution only due to their dependencies on the application server's state or specific session data.
  
  
  Configuration Issues: There may be configuration settings that restrict certain functions from being called remotely.
  
  
  Incorrect Usage: The function might be used in a context that does not support remote execution, such as certain types of transactions or processes that require a user interface.
  
  
  Solution:
  
  
  Check Function Module: Review the function module or method you are trying to call. Check the documentation to see if it is marked as "not remote-enabled." If it is not, you will need to find an alternative approach.
  
  
  Use Alternative Functions: Look for alternative function modules or methods that provide similar functionality and are designed to be called remotely. SAP often provides remote-enabled versions of certain functions.
  
  
  Modify the Call: If you have control over the code, consider modifying the call to use a different approach that does not require remote execution.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide guidance on how to handle it.
  
  
  Debugging: If you have access to the system, you can debug the code to see exactly where the error is occurring and gather more context about the function being called.
