Enhance Standard Selection screen of RPLICO10

Hi Friends,

I am a ABAPer,

I am facing one problem in standard report RPLICO10 or tcode s_ahr_61016362.

Actually My functional team want to add more list when they click on additional data(field selection).

After click ,some list is coming ,they want to add some more information like infotype 21 details .

How can I add in that standard list?

As per my observation it is using PNP ldb ,some structure in standard program .

I try to follow sap notes or thread like http://scn.sap.com/thread/1545430.

But that not helpful.

I am attaching screenshot.

Any help from Functional side ? Anyone faced  this issue?

Does it related to report category?

Thanks

Gourav.
