Short Employee Profile in MSS

HI ALL,

I have one question on Short Employee Profile under Profile Application under MSS .

Contract Data for employee profile is fetching data from PA20 Infotype 0001, but we need to change the config/code such that it fetches data from Infotype 0016 instead.

Can anyone please help me in finding place where I need to change such that Contract Data fetches data from Infotyp;e 0016

Thanks

Anu
