  WA652 Receiver function module &: Invalid name for a function module
  
  Cause:
  This error occurs when the system tries to call or reference a function module whose name is invalid or does not conform to SAP naming conventions. The function module name might be:
  
  Empty or missing.
  Contain invalid characters.
  Exceed the allowed length.
  Not exist in the system (typo or incorrect name).
  Not properly maintained in the configuration or interface settings.
  
  In the context of ALE/IDoc processing or RFC calls, this error typically means that the receiver function module name specified in the partner profile or in the program is incorrect or missing.
  
  Solution:
  
  
  Check the Function Module Name:
  
  Verify the function module name being called.
  Ensure it exists in the system (use transaction SE37 to check).
  Confirm the name follows SAP naming conventions (starts with a letter, no special characters, max length 30).
  
  
  
  Check Partner Profile / ALE Configuration:
  
  If this error occurs during IDoc processing, check the partner profile (transaction WE20).
  Verify the receiver function module name configured for inbound processing.
  Correct any typos or missing entries.
  
  
  
  Check the Program or Interface Code:
  
  If the function module name is dynamically determined in code, debug to see what name is being passed.
  Fix the logic to pass a valid function module name.
  
  
  
  Transport or System Issues:
  
  If the function module exists in the development system but not in the target system, ensure transports are properly imported.
  Check for missing or incomplete transports.
  
  
  
  Recreate or Correct the Function Module:
  
  If the function module is custom and missing, create or restore it.
  If standard, check SAP Notes or support for missing standard function modules.
