Duet Enterprise - [ERROR] - "Cannot Merge Contents of LobSystem (External System) with Name 'Account' as it appears to be different from preexisting LobSystem in the current load context." - Fix

When using Duet Enterprise (for SAP and SharePoint 2010 Integration) you may receive the following exception when importing Duet Business Connectivity Service Models (as per http://technet.microsoft.com/en-us/library/gg394164.aspx):

"Duet Enterprise - [ERROR] - Cannot Merge Contents of LobSystem (External System) with Name 'Account' as it appears to be different from preexisting LobSystem in the current load context.".

This may occur even after you've used Duet to remove all of the models with the commandline DuetConfig.exe /RemoveBDC.

You can fix this issue by going to:

This may occur even after you've used Duet to remove all of the models with the commandline DuetConfig.exe /RemoveBDC.

SharePoint Central Administration - Your Business Connectivity Services (BCS) Service Application - Manage
Then:

1) Choose "Models" in the "View" dropdown and remove any Duet models if they still exist
2) Choose "External Systems" and Remove any Duet External systems (this is the external system referred to in the error).


You should now successfully be able to import the Duet Enterprise 1.0 out of the box Models.
