MDG-C: DB New Search Enhancement option

Hi Experts,

At initial screen , we have couple of option to search .

We wanted to add new option called Account group search.

Basically user wanted to search based on Account Group.

Can anyone help me on How to add new search options ?

I would like to Query KNA1 and one of our Z table and display at result table .

One option I could see based on my analysis

- Create a class, with this interface IF_USMD_SEARCH_DATA

- Add this class at MDGIMG -> General settings -> Data quality and Search -> Search and Duplicate check -> Define search application 

- Add new Option here

Like for Material we have this document available at SDN

Note : We are at MDG 7.0.

Varun
