I'm very much beginner to Adobe Target . I have implemented adobe target using Adobe Launch with extension at.js and passing a default global variable sitename in to Target. Now I got a new request asking about to setup a Propertie. I'm confused that I have already done the implementation using launch but what is the need of properties and how it is helpful.
Basically you can for example ensure that somebody with access to Target can only adapt the American website and not the German website. You would then create 2 different workspaces:
America workspace ===> linked to property A
German workspace ==> linked to property B
So you would put the property code using your tag manager on the different websites and in the Admin console you link the property to the right workspace. You can then give your users access to the workspaces they need.
