When configuring a Data Source Connection in App Store Connect you have the option to specify username and password credentials. However, this may not always be desired.
Rather than specify explicit credentials in the connection object, you may prefer to have the underlying App Store Connect Windows Service employ an account that has data access permissions.
The following instructions describe how to enable this process:
1. Do not specify user credentials in Data Source Connection
If left blank the default behaviour is to use App Store Connect service account.
2. Service Account Security
As well as PI Access, the service account should have rights configured on the local server folder:
3. Modify the App Store Connect Service Account
3.1 In Windows Services, select: Intelligent Plant Data Core Service
3.2. Change default Local System account to preferred alternative.
