• What is the cause and solution for SAP error message WA670 - Receiver type determination function module & not found ?

  The SAP error message:
  WA670 Receiver type determination function module & not found
  typically occurs in the context of IDoc processing or ALE (Application Link Enabling) when the system tries to determine the receiver partner type but cannot find the specified function module.
  
  Cause
  
  The system is configured to use a custom or standard function module for determining the receiver type in partner profiles or distribution model.
  The function module name specified in the partner profile or distribution model does not exist or is not active in the system.
  Possible reasons:
  
  Typo or incorrect function module name entered.
  The function module was deleted or not transported to the system.
  The function module is not released or not properly implemented.
  The system expects a standard function module, but none is assigned.
  
  
  
  
  Where it occurs
  
  In partner profiles (transaction WE20) under the outbound parameters, when the "Receiver type determination" is set to use a function module.
  In the distribution model (transaction BD64) or in the ALE configuration.
  During IDoc processing or message sending, when the system tries to determine the receiver type dynamically.
  
  
  Solution
  
  
  Check the function module name:
  
  Go to transaction WE20.
  Select the partner profile and outbound parameters.
  Check the "Receiver type determination" function module name.
  Verify the function module name is correct.
  
  
  
  Verify the function module exists:
  
  Use transaction SE37 to check if the function module exists.
  If it does not exist, you need to create or import it.
  
  
  
  If a custom function module is used:
  
  Ensure it is properly implemented and released.
  Check the code for correctness.
  Transport it to the system if missing.
  
  
  
  If no custom function module is needed:
  
  Remove the function module name from the partner profile.
  Use standard receiver type determination methods (e.g., fixed receiver type).
  
  
  
  Check the distribution model:
  
  In transaction BD64, check if any function module is assigned for receiver type determination.
  Correct or remove it if invalid.
  
  
  
  Check SAP Notes:
  
  Sometimes SAP releases notes related to this error for specific versions or scenarios.
  
  
  
  
  Additional Information
  
  The receiver type is important for IDoc processing because it defines how the system processes the IDoc for the receiver (e.g., whether the receiver is a logical system, a port, or a partner).
  The function module used for receiver type determination must have the correct interface and return the expected receiver type.
  Standard SAP function modules for receiver type determination include:
  
  IDOC_RECEIVER_TYPE_DETERMINE
  SOME_CUSTOM_FUNCTION_MODULE (custom implementations)
