It is possible to setup both a list view and a notification filter that will show you when data items are assigned to you. To do this you need to use the following path (if you are interested in cells being assigned)
This path can be added to a list view, or a notification filter. Examples of both are shown below:
To use these example save the files and use file --> Import. For the notifier you will need to make sure it is enabled.
This works by comparing the user name that you (or the console more specifically) used to login into the gateway with the name of the user assignment, an example of which is shown below.
The match on whether an assigned item will appear in the above list or notifier is based on your login to the gateway. You can the user namethis by building the following path in the path editor (tools --> path editor --> dataitem Path Editor'
This should also highlight whether the domain for the username is included or not. I.E. Domain/Username vs just username. If the domain is included you should try the following path instead.
