  The SAP error message /IWBEP/CM_SBMC_MPC029 Transport is not specified for MPC generation typically occurs in the context of SAP Gateway and OData service development. This error indicates that the system is unable to generate the Model Provider Class (MPC) because a transport request has not been specified.
  Cause:
  
  Missing Transport Request: The most common cause of this error is that a transport request has not been assigned to the development object (like the MPC or DPC classes) that you are trying to generate.
  Development Environment: If you are working in a local development environment (like a sandbox), you may not have a transport request created or assigned.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to create or assign transport requests.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Create a Transport Request:
  
  Go to transaction SE09 or SE10 (Transport Organizer).
  Create a new transport request if one does not exist.
  
  
  
  Assign the Transport Request:
  
  Open the relevant development object (MPC or DPC).
  In the object’s properties, assign the newly created transport request.
  Save the changes.
  
  
  
  Generate the MPC/DPC:
  
  After assigning the transport request, try to regenerate the MPC and DPC classes again.
  You can do this by using transaction SEGW (Service Builder) and selecting the appropriate service, then choosing the "Generate" option.
  
  
  
  Check Authorizations:
  
  Ensure that you have the necessary authorizations to create and manage transport requests. If you do not have the required permissions, contact your SAP Basis or security team.
  
  
  
  Check System Settings:
