It is possible to view custom variables as a column in Listviews.
First, we need to create a custom variable, see Administrator Manual Overview.
To create a column in listviews for the custom variable:
- Go to Configuration > My Account.
- Add the following to "table host" or "table service".
default, "Asset ID" = custom_variables.ASSETID
The in the example above we use the custom variable "_ASSETID".
