Org Unit determination based on Emp Resp in Task

Hi...

I am using the standard transaction type TASK, and want to determine the Org Units Sales Org, Distribution Channel and Division based on the value entered for employee responsible. I have these employees to Sales Organization in the Org model under Positions. For the sales Org, I have maintained country as the attribute and released it. My requirement is to see the corresponding Org Units in the TASK transaction depending on the country of the Employee responsible.

Appreciate your help.

Regards
