Find where is selected all data after a selection of an Account

Hi experts.

I need to find where is selected the data for a BP after you select it on the account search results.

In the component BP_HEAD_SEARCH/MainSearchResult, I understood that system goes with this path

event : EH_ONSINGLESELECTION

outbound plug : OP_SINGLESELECTION

In this OP, we call the MainWindow OP TOOVERVIEW

But when i check the Main window no coding is inside the method OP_TOOVERVIEW so i'm unable to track the data.

So i have to questions :

1. How can i find where the OP_TOOVERVIEW is sending the request

2. After the selection of a BP, does anybody knows where are retrieved the data like completed activities ? Wich component and method ?

Thanks for your help.

Regards,

Helder
