For the Organisation Chart to work, we must configure the root organisation, i.e. the top level of the organisation structure. For you, this might be an organisation called something like "MyCompany"
To complete the set-up follow these steps:
- Define what the top level of the organisation is e.g. MyCompany
- Navigate to EA Support > Essential Viewer > Report Configuration > Report Constant
- Select the Org Model - Root Organisation instance
- Click ADD in the Associated Instances slot and select the Group Actor that has been defined as the top level for this organisation
