• What is the cause and solution for SAP error message EH303 - AMI and non-AMI devices cannot be selected at the same time ?

  The SAP error message EH303 indicates that there is an issue with selecting both AMI (Advanced Metering Infrastructure) and non-AMI devices simultaneously in a transaction or process. This error typically arises in the context of utilities management, particularly in the handling of meter data and device management.
  Cause:
  The primary cause of this error is that the system does not allow the simultaneous selection of AMI and non-AMI devices due to differences in their data handling, processing, and operational requirements. AMI devices are typically smart meters that provide real-time data and advanced functionalities, while non-AMI devices are traditional meters that may not support such features.
  Solution:
  To resolve this error, you should ensure that you are only selecting either AMI devices or non-AMI devices, but not both at the same time. Here are the steps you can take:
  
  
  Review Your Selection Criteria: Check the criteria or filters you are using to select devices. Make sure that you are filtering for either AMI or non-AMI devices exclusively.
  
  
  Separate Transactions: If you need to work with both types of devices, consider performing separate transactions for AMI and non-AMI devices. This means running one process for AMI devices and another for non-AMI devices.
  
  
  Check Configuration Settings: If you believe that the selection should be allowed, review the configuration settings in your SAP system. There may be settings that restrict the selection of both types of devices together.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources specific to your version of SAP for any additional guidelines or restrictions regarding device selection.
  
  
  Contact Support: If the issue persists and you are unable to resolve it, consider reaching out to your SAP support team or consulting with an SAP expert who can provide further assistance.
