custom HRESS_CC_PER_CONFIG brings no data available on ESS Personal Data

Hi Gurus,

I am looking for some guidance for a issue I am encountering on ESS Personal Data (Over view screen / Biz card):

This was the original settings which was working fine:

And as the result of this setting, I am getting this data on the ESS Personal data as shown:

Now, when I change my Custom App CC setting to say: From "HRESS_CC_PER_OVR_PERSDATA_XX" to "ZHRESS_CC_PER_OVR_PERSDATA_US" (Please note, the Z version is a copy of the standard "HRESS_CC_PER_OVR_PERSDATA_US"), I am getting a message as "No data available" as shown below:

Am I missing anything other than changing the Custom App CC and including it in my custom Application ? Anybody any suggestions are most welcome.

Thanks!
Karthik Kumaaravel.
