How to store data in data service using UiPath studio

I’m building one automation where in the studio I’m getting some output values that I want to store in data service for example name, USN and marks.
I’m fetching these values from ui automation and I want to store these results into data service. How can I do that?

have a look here:
https://docs.uipath.com/activities/other/latest/workflow/create-entity-record

@ppr I checked this activity but I’m unable to select any entity. It shows no entities found but I’ve created entity in data service

have you referenced the UiPath.DataService.activities?
AND
configured the Data Service Entitites
And
checked the needed permission to get Access
And
is the entitity shown within the Data Manager?

@ppr can you tell me how to provide permission to get access?

However:

with this you can quick-check, if access is available or not
