Hi Mukti
The pac_mnt_resources table contains financial information. It gets the resource entry inserted when the resource financial properties are entered. If your newly created resource is not financially enabled, it will not be in pac_mnt_resources.
Please go to Resource - Properties - Financial and enable the resource financially and you will see it in the table.
Concerning odf_ca_resource and the column jp_active_feed - this is a table containing your custom attributes. You should find your custom attribute jp_active_feed in the Resource properties view and populate it, then you will see it. If the attribute is not in the view, you will have to add it to Resource - Edit and then you will be able to see it and populate it.
Hope this helps -Nika
