EG31 - Device location created does not have premise populated

Hi experts,

Need your help or experience if you have seen this problem before:

When I'm installing a device using t-code EG31 by specifying installation or Connection object and Device, a new device location is created but that device location is not populated with the premise information although premise is a mandatory field in the device location.

I'm not sure if its standard SAP bug. I've tried to look for an SAP note but couldn't find any.

Is it standard behavior? It doesn't seem to me because how can an object be created without populating all the mandatory fields in the transactions unless its a direct insert in the table instead of going through all the validation check either through a BAPI or a other check routines.

Any input will be helpful..

Thanks,
