  SAP Error Message:
  
  WES_OUTBOUND068 – "You cannot use structure &1"
  
  Cause:
  This error typically occurs in the context of SAP PI/PO (Process Integration/Process Orchestration) or SAP middleware when dealing with IDoc or proxy message mappings. The message indicates that a particular structure (denoted by &1, which is replaced by the actual structure name in the runtime message) cannot be used in the outbound processing.
  Common causes include:
  
  The structure is not allowed or supported in the outbound interface or message type.
  The structure is marked as inbound-only or is restricted for outbound use.
  The mapping or interface definition is trying to use a structure that is not part of the outbound message schema.
  There is a mismatch between the message type or namespace expected and the structure being used.
  The structure is deprecated or not released for outbound processing in the system.
  
  
  Solution:
  To resolve the error:
  
  
  Check the Structure Name:
  
  Identify the structure name (&1) from the error message.
  
  
  Verify Interface and Message Type:
  
  Confirm that the structure is valid and allowed in the outbound interface/message type you are working with.
  
  
  Review the Message Mapping:  
  
  Ensure that the mapping does not use structures that are inbound-only or not part of the outbound message.
  Adjust the mapping to use the correct structure(s) as per the outbound message definition.
  
  
  
  Check IDoc or Proxy Definitions:  
  
  For IDocs, verify that the segment/structure is part of the outbound IDoc type.
  For proxies, check the generated proxy classes and ensure the structure is available for outbound messages.
  
  
  
  Adjust Interface or Message Type if Needed:
  
  If the structure is required but not allowed, you may need to extend or adjust the interface/message type definitions to include the structure for outbound use.
