From 61d8e7c73b0b55a529fe7e9cb0cccccf50ee967a Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 13 Jun 2018 16:00:11 +0530 Subject: OPP: Identify and mark genpd OPP tables We need to handle genpd OPP tables differently, this is already the case at one location and will be extended going forward. Add another field to the OPP table to check if the table belongs to a genpd or not.
