  SAP Error Message:
  WT236 - Error while starting RFC: No PBT resources configured in the system
  
  
  Cause:
  This error occurs when the system tries to start an RFC (Remote Function Call) connection related to the Process-Based Transport (PBT) framework, but no PBT resources have been configured in the system. Essentially, the system expects certain PBT resources (like transport routes, transport layers, or related configuration objects) to be set up, but they are missing or incomplete.
  PBT is used in SAP Solution Manager and CTS+ (Change and Transport System Plus) scenarios to manage transports in non-ABAP systems or complex landscapes. If the PBT infrastructure is not properly configured, attempts to start RFCs related to PBT will fail with this error.
  
  When does this error typically occur?
  
  When using CTS+ for transporting objects in non-ABAP systems.
  When the system tries to communicate with PBT resources via RFC but finds none
