• What is the cause and solution for SAP error message WT236 - Error while starting RFC: No PBT resources configured in the system ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  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 configured.
  During transport or change management operations involving PBT.
  In Solution Manager or managed systems where PBT is expected but not set up.
  
  
  Solution:
  
  
  Check PBT Configuration:
  
  Go to transaction STMS or STMS_IMPORT and verify if PBT resources are configured.
  In Solution Manager, check the CTS+ configuration for the managed system.
  Ensure that the PBT transport routes and layers are properly defined.
  
  
  
  Configure PBT Resources:
  
  If no PBT resources exist, create and configure them according to your landscape requirements.
  Use transaction SPRO ? SAP Reference IMG ? Change and Transport System ? CTS+ ? Configure PBT resources.
  Define transport routes, transport layers, and assign them to the relevant systems.
  
  
  
  Check RFC Destinations:
  
  Verify the RFC destinations used for PBT communication (transaction SM59).
  Ensure that the RFC destinations are correctly set up and tested.
  
  
  
  Restart or Reinitialize the RFC Connection:
  
  After configuration, restart the RFC connection or the related services.
  You can test the RFC connection in SM59.
  
  
  
  Check Authorizations:
  
  Ensure that the user used in the RFC connection has the necessary authorizations to access PBT resources.
  
  
  
  SAP Notes and Documentation:
  
  Check for relevant SAP Notes related to PBT and CTS+ configuration.
  For example, SAP Note 1788700 and others related to CTS+ and PBT setup.

  Summary:
  The error WT236 indicates missing PBT resources configuration in the system, causing RFC startup failure. To resolve it, verify and configure the PBT resources properly in your system landscape, ensure RFC destinations are correct, and check authorizations. This is crucial in environments using CTS+ for transport management.
  
  If you need help with specific configuration steps or further troubleshooting, please provide details about your system landscape and the context in which the error occurs.
