  To resolve this error, you can take the following steps:
  
  Check Routing and BOM: Ensure that the routing for the production order is correctly defined and that all necessary operations and successors are included.
  Review Master Data: Verify that the master data (like material master, work center, etc.) is correctly set up and that there are no missing or incorrect entries.
  Check Production Order: Look at the specific production order or planning object that is causing the error. Ensure that all operations are correctly sequenced and that successors are defined.
  Adjust Planning Parameters: Review and adjust the planning parameters in the system to ensure they align with the production process.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the error message and related configuration settings.
  Debugging: If you have access to technical resources, consider debugging the process to identify where the token is failing to find successors.
