  The SAP error message G00056 indicates that there is an issue with the task group configuration in a project or process. Specifically, it states that the last task in a task group cannot have any successor tasks.

  Reorganize Tasks: If you need to add more tasks after the last task, consider restructuring your task group. You may need to create a new task group or adjust the sequence of tasks.
  
  
  Consult Documentation: Refer to SAP documentation or guidelines related to task groups and project management to ensure compliance with best practices.
