Prerequisites
Logging into the Package
Prerequisites
You need:
Elements account
Space where you are the Space Admin (e.g. if you created the Space)
Salesforce connection established from the Elements app and an Org Model synced
Logging into the Package
Select the Elements App within Salesforce
Select the Elements Settings tab.
Elements Accounts Tab
The Elements Account tab is used to connect a Salesforce Org to an Elements Space. An Org can only be connected to one Space.
Simply log in to the package using your Elements credentials (username & password). The package will then automatically connect to the already synced org model.
That's it! You can now configure SSO for other users in your Org and get field % population data in your Org model.
