• What is the cause and solution for SAP error message EG105 - You cannot change device group; allocations exist ?

  The SAP error message EG105 ("You cannot change device group; allocations exist") typically occurs when you attempt to change the device group of a device that has existing allocations or assignments. This is common in scenarios involving resource management, such as in SAP PM (Plant Maintenance) or SAP EAM (Enterprise Asset Management).
  Cause:
  The error is triggered because the system has detected that the device you are trying to modify is currently linked to existing allocations, such as maintenance orders, work orders, or other operational activities. Changing the device group while these allocations exist could lead to inconsistencies in data and reporting.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Allocations: Identify the allocations or assignments that are currently linked to the device. You can do this by reviewing the maintenance orders, work orders, or any other relevant documents that reference the device.
  
  
  Remove or Complete Allocations: 
  
  If possible, complete or close the existing allocations. This may involve finishing maintenance tasks or closing work orders that are currently using the device.
  If the allocations are not needed, you can delete or unassign them.
  
  
  
  Change Device Group: Once all allocations have been addressed (either completed or removed), you should be able to change the device group without encountering the error.
  
  
  Reassign Allocations: If necessary, after changing the device group, you can reassign any relevant allocations to the new device group.
  
  
  Related Information:

  Documentation: Refer to SAP documentation or your organization's guidelines for managing device groups and allocations to ensure compliance with internal processes.
