PNP and PNPCE databases in ESS

HI,

As all you know standard ESS works on PNP logical database.but we have a situation in our project that we should use PNPCE database instead of PNP.

So i would like to get your inputs on the usage of PNPCE in ESS .will there be any bad impact of using that database

helpful inputs will be rewarded
