Executing Process having User interaction when Screen is locked

We have created workflow in which SAP transactions are executed and data is extracted in excel format.
This workflow requires interaction with screen. We have created windows scheduled task to run this workflow
Now this works fine if screen is not locked.
But when machine is locked it does not work
We want to run this process at night and all every one hour.
Hence user may not have lock that terminal.
we cannot let computer running without locking it
Is there any solution for this

Just curious…can uipath work on locked pc?
