how to change the Org Data depending on the Person Responsible?

Hi Group,

I have a requirement relating to Org data changing as :

while creating the activities in CRM, by default I was getting the <b>Org data</b> for the person responsible ( whoever has created the <b>Activity</b> ).

there is a provision that, we can change the <b>Person Responsible</b> for the Activity.

and when the <b>Person Resp</b> is changed, the <b>Org data</b> also to be changed accordingly....

But, this was not happening due to some technical reasons....

So please give me some inputs as how to change the <b>Org data</b> according to the changes to the <b>Person Resp</b>.

Thanks in advance.

Regards,

Vishnu.
