Hi Anjum,
If you are writing logic in BOL Level, Will have Bol relations for getting Mail Id's and all.
From me->typed_context you ll get the current value, either Trans id or anything related to that View.
So if u got the current entity, then by using Relations we can easily get the Mail Id's.
For that u need to find relations from GENIL_MODEL_BROWSER, Put ur component set and search relations.
Let me know if u need more help.
Thanks & Regards,
Arunpandi.
