Can I customized the column view based on a data that is not extracted from the device?
I suggest using the configurable Device Name value for tracking Asset Numbers. For other data you can apply Custom Attributes to the devices manually and then you should be able to use the Custom Attribute name is a column in that view. You can do so in 13.3 at least, so I would expect you could do the same in 14+.
First, You have to create a Custom Attribute that you can assign to devices in the Global Settings.
Next, you have to go back to the device page and assign Custom Attribute Values to your devices. To do this, select a device and while on the "Device Details" tab, scroll down to "Custom Attributes" and Assign a value to the device.
Finally, while on the "View Devices" page, you can click on "Columns View: Default" to change the columns that appear for devices. Your Custom attribute should be in this list. Select it, and it will appear as a column.
If at any point any of this does not work, contact Tech Support and get a Support Case opened. Everything I've mentioned in this post is expected behaviour and any deviation should be considered a Support issue to be fixed.
My next question is,
Is it possible in version 14 to specify the attribute value for each devices through a csv file and will be imported to Mobicontrol server?
