• What is the cause and solution for SAP error message PO368 - Not all device classes match the pool device class ?

  The SAP error message PO368, which states "Not all device classes match the pool device class," typically occurs in the context of SAP's print management system. This error indicates that there is a mismatch between the device classes of the printers defined in a print pool and the device class of the pool itself.
  Cause:
  
  
  Device Class Mismatch: The primary cause of this error is that the printers assigned to a print pool do not share the same device class as the print pool. For example, if the print pool is defined for a specific type of printer (like laser printers), but the printers assigned to it are of a different type (like dot matrix printers), this error will occur.
  
  
  Configuration Issues: There may be configuration issues in the SAP system where the device classes of the printers and the pool are not aligned.
  
  
  Changes in Printer Configuration: If there have been recent changes to the printer configurations or the print pool settings, this could lead to inconsistencies.
  
  
  Solution:
  To resolve the PO368 error, follow these steps:
  
  
  Check Device Classes:
  
  Go to the SAP transaction code SPAD (Spool Administration).
  Navigate to the "Output Devices" section and check the device classes of the printers assigned to the print pool.
  Ensure that all printers in the pool have the same device class as the print pool.
  
  
  
  Modify Print Pool Settings:
  
  If necessary, modify the print pool settings to match the device classes of the printers assigned to it.
  You can do this by going to the "Output Devices" section in SPAD, selecting the print pool, and adjusting its device class.
  
  
  
  Reassign Printers:
  
  If some printers do not match the required device class, consider reassigning them to a different print pool that matches their device class or changing their device class if appropriate.
  
  
  
  Test Printing:
  
  After making the necessary adjustments, perform a test print to ensure that the error has been resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SPAD (Spool Administration) and SP01 (Spool Request) for managing and troubleshooting print issues.
  Documentation: Refer to SAP documentation or help resources for detailed information on configuring output devices and print pools.
  User Roles: Ensure that you have the necessary authorizations to make changes in the SPAD transaction, as some settings may be restricted based on user roles.
  
  By following these steps, you should be able to resolve the PO368 error and ensure that your print configurations are correctly set up in SAP.
