• What is the cause and solution for SAP error message EN035 - Device &1 is already allocated to installation &2 ?

  The SAP error message EN035 indicates that a device (such as a meter or other equipment) is already allocated to a different installation. This typically occurs in the context of SAP IS-U (Industry Solution for Utilities) when trying to assign a device to an installation that is already in use.
  Cause:
  
  Device Already Assigned: The device you are trying to allocate is already assigned to another installation.
  Incorrect Installation Number: You may be trying to assign the device to an installation that is not valid or does not exist.
  Data Inconsistency: There may be inconsistencies in the database or transaction logs that prevent the allocation.
  
  Solution:
  
  
  Check Current Allocation: Verify which installation the device is currently allocated to. You can do this by checking the device master data in the SAP system.
  
  Use transaction codes like IE03 (Display Equipment) or EAM (Enterprise Asset Management) to view the device details.
  
  
  
  Reallocate the Device: If the device needs to be moved to a new installation, you may need to first remove it from the current installation. This can be done using:
  
  Transaction code IE02 (Change Equipment) to change the allocation.
  Ensure that the device is not in use or locked by any ongoing processes.
  
  
  
  Check for Open Transactions: Ensure that there are no open transactions or processes that are using the device. If there are, you may need to complete or cancel those transactions before reallocating the device.
  
  
  Consult with IT Support: If you are unable to resolve the issue, it may be necessary to consult with your SAP support team or IT department. They can help investigate any underlying data issues or system configurations that may be causing the problem.
