ESS - Qualification catalog

Hi,

I am new to ESS, my requirement is to add a link to existing list on ESS (Personal data, address etc.,) for the employees to update the languages they speak.

I have gone through some posts and created the required language catalog (OOQA), cross checked the entries in T77S0 for QUALI, maintained an entry QUALI ESSST in Define root qualification group of SPRO ESS.

But, i am not sure of the steps to add the link on ESS and update the backend. Would really appreciate if someone can advise me on the steps to follow and prerequisites.

Thanks,
