Get All Parameters in database

Hello all,
I am new to genieacs. I need to set some parameter values. Those parameters are not available in database. So for testing purpose I built those parameter from Device.xml and override the collection devices of mongo. But genieacs api deletes those parameters automatically. How can i get them into database permanently?
For example: DeviceID.Manufacturer
Above parameter we find after connecting the device. But the following parameter i don’t get in the database
Device.Services.FAPService.1.FAPControl.UMTS.AdminState

How can i get that parameter into database?

Any of the DeviceID.* are generated by GenieACS and not part of the CPEs data model.

Have you refreshed the Device.Services parameter?
