• What is the cause and solution for SAP error message /PF1/MSG_FH_GUI406 - Converter not found for format &1, medium &2, channel &3, outgoing PO &4 ?

  The SAP error message /PF1/MSG_FH_GUI406 indicates that the system is unable to find a converter for a specific format, medium, and channel related to an outgoing Purchase Order (PO). This error typically arises in the context of document processing, especially when dealing with electronic data interchange (EDI) or similar document formats.
  Cause:
  
  Missing Converter: The most common cause is that the required converter for the specified format (e.g., IDoc, XML, etc.) is not defined or is missing in the system.
  Incorrect Configuration: The configuration settings for the output medium or channel may not be set up correctly, leading to the system being unable to find the appropriate converter.
  Incompatible Format: The format specified may not be supported by the current system configuration or may not be compatible with the medium/channel being used.
  Transport Issues: If the system has recently undergone a transport or upgrade, the necessary components for the converter may not have been transported correctly.
  
  Solution:
  
  
  Check Converter Configuration:
  
  Go to transaction WE41 (for output types) or WE42 (for inbound processing) to check if the converter for the specified format is defined.
  Ensure that the converter is correctly configured for the specified medium and channel.
  
  
  
  Review Output Type Settings:
  
  Check the output type associated with the outgoing PO. Ensure that it is correctly configured to use the appropriate format and medium.
  You can do this in transaction NACE, where you can find the output type settings for purchasing documents.
  
  
  
  Verify Medium and Channel:
  
  Ensure that the medium (e.g., print, EDI, email) and channel (e.g., FTP, HTTP) are correctly set up in the system.
  Check the configuration in transaction SPRO under the relevant sections for EDI or output processing.
  
  
  
  Check for Missing Components:
  
  If the system has been recently upgraded or transported, verify that all necessary components for the converter are present in the system.
  You may need to re-transport or reconfigure the missing components.
