• What is the cause and solution for SAP error message EH301 - Only one AMI device can be selected in a reconnection order ?

  The SAP error message EH301, which states "Only one AMI device can be selected in a reconnection order," typically occurs in the context of Advanced Metering Infrastructure (AMI) within SAP IS-U (Industry Solution for Utilities). This error indicates that the system is expecting only one AMI device to be selected for a specific reconnection order, but it has detected multiple devices instead.
  Cause:
  
  Multiple AMI Devices: The primary cause of this error is that the system has identified more than one AMI device associated with the same reconnection order. This can happen if the configuration or data entry allows for multiple devices to be linked to a single order.
  Data Integrity Issues: There may be inconsistencies or errors in the master data related to the AMI devices, such as incorrect assignments or duplicates.
  Process Misconfiguration: The business process or workflow may not be correctly set up to handle multiple devices in a reconnection scenario.
  
  Solution:
  
  Review the Reconnection Order: Check the reconnection order in question to ensure that it is only associated with one AMI device. If multiple devices are linked, determine which one should be selected for the reconnection.
  Data Cleanup: If there are data integrity issues, clean up the master data related to the AMI devices. This may involve removing duplicates or correcting assignments.
  Adjust Configuration: If the business process allows for multiple devices but the system does not support it, consider adjusting the configuration or workflow to accommodate the business needs.
  Consult Documentation: Review SAP documentation or notes related to AMI and reconnection orders for any specific guidelines or updates that may address this issue.
  Contact SAP Support: If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They may provide patches or additional insights based on the specific version of your SAP system.
  
  Related Information:

  User Roles and Authorizations: Ensure that the user attempting to perform the reconnection has the necessary roles and authorizations to manage AMI devices and orders.
