  The SAP error message IDOC_ADAPTER404 "No IDoc type passed" typically occurs when there is an issue with the configuration or the data being processed in the IDoc interface. This error indicates that the system is unable to identify the IDoc type that should be processed, which is essential for the correct handling of IDocs.
  Causes:
  
  Missing IDoc Type: The IDoc type is not specified in the configuration or the data being sent.
  Incorrect Mapping: The mapping between the source and target systems may not be correctly defined, leading to the absence of an IDoc type.
  Configuration Issues: The IDoc adapter configuration in the SAP system may not be set up correctly.
  Data Issues: The data being sent may not conform to the expected structure, leading to the inability to determine the IDoc type.
  Transport Issues: If the IDoc is being sent from one system to another, there may be transport issues that prevent the IDoc type from being recognized.
  
  Solutions:
  
  
  Check IDoc Type Configuration:
  
  Ensure that the IDoc type is correctly defined in the system. You can check this in transaction WE30 (IDoc Types) and ensure that the IDoc type you are trying to use exists and is active.
  
  
  
  Review Mapping:

  Validate Data:
  
  Ensure that the data being sent includes the necessary fields that define the IDoc type. If you are generating IDocs programmatically, make sure that the IDoc type is specified in the code.
  
  
  
  Check Partner Profiles:
  
  In transaction WE20 (Partner Profiles), verify that the partner profile for the sending or receiving system is correctly configured to handle the specific IDoc type.
  
  
  
  Review Application Logs:

  Consult Documentation:
  
  Review SAP documentation or notes related to IDocs and the specific IDoc type you are working with for any known issues or additional configuration steps.
