• What is the cause and solution for SAP error message CPWB815 - Production resource/tool is displayed in new session ?

  The SAP error message CPWB815, which states "Production resource/tool is displayed in new session," typically occurs in the context of the SAP Production Planning (PP) module, particularly when working with production resources/tools (PRTs) in the Capacity Planning Workbench (CPWB).
  Cause:
  This error usually arises when:
  
  Session Management: The system is trying to open a new session for a production resource/tool that is already being accessed in another session. SAP restricts multiple accesses to the same resource to prevent data inconsistencies.
  Locking Mechanism: The locking mechanism in SAP prevents simultaneous changes to the same object, which can lead to this error if another user or session is already using the resource.
  Configuration Issues: There may be configuration settings that dictate how resources are managed and displayed in the system.
  
  Solution:
  To resolve the CPWB815 error, you can try the following steps:
  
  Close Other Sessions: Check if you have multiple sessions open that are accessing the same production resource/tool. Close any unnecessary sessions.
  Log Off Other Users: If other users are accessing the same resource, coordinate with them to log off or release the resource.
  Use Transaction Codes: Instead of accessing the resource through the CPWB, try using specific transaction codes (like CR01, CR02 for creating or changing resources) to access the resource directly.
  Check for Locks: Use transaction code SM12 to check for any locks on the resource. If you find locks that are no longer needed, you can delete them (ensure you have the necessary authorizations).
  System Restart: In some cases, a system restart may help clear any lingering sessions or locks.
  Consult Documentation: Review SAP documentation or notes related to the specific version of SAP you are using, as there may be known issues or patches available.
