  Error Message
  WZRE_IDOC007: Specify a message type
  
  Cause
  This error occurs when the system expects a message type to be specified for an IDoc processing step, but it is missing or not provided. In SAP IDoc processing, the message type is a crucial parameter that defines the kind of business document or message the IDoc represents (e.g., ORDERS for purchase orders, INVOIC for invoices).
  Common causes include:
  
  The IDoc processing function module or program is called without specifying the message type.
  Configuration or mapping missing in the partner profile or port definition.
  Custom code or middleware interface not passing the message type parameter.
  Incorrect or incomplete IDoc generation or inbound processing setup.
  
  
  Solution
  To resolve the error, ensure that the message type is correctly specified wherever the IDoc is created, processed, or transmitted.
  Steps to fix:
  
  
  Check Partner Profile (WE20):  
  
  Verify that the partner profile for the sender/receiver has the correct message type assigned for the relevant message function.
  Ensure inbound and outbound parameters include the message type.
  
  
  
  Verify Port Definition (WE21):  
  
  Confirm that the port used for IDoc communication is correctly configured and linked to the appropriate message type.
  
  
  
  Review IDoc Generation Code or Middleware:  
  
  If custom programs or middleware generate IDocs, check that the message type is passed correctly in the function module calls (e.g., MASTER_IDOC_DISTRIBUTE or IDOC_INBOUND_ASYNCHRONOUS).
  For example, when calling MASTER_IDOC_DISTRIBUTE, the OBJECT_TYPE and MESSAGE_TYPE parameters must be filled.
  
  
  
  Inbound Processing Configuration:  
  
  Check the inbound process code and message type assignment in transaction WE42 or WE57.
  Make sure the inbound processing function module is linked to the correct message type.
  
  
  
  Reprocess the IDoc:  
  
  After correcting the message type, reprocess the IDoc via transaction WE19 or WE02/WE05.
