Populating supervisor based on position

Question

Hi friends,
I have an issue while making changes in the custom.pll code. The requirement is when the organization and position are entered in the assignment screen I should populate the supervisor accordingly based on the org and position.(we have a package to get this). I am trying to write this code but somehow it does not populate after the position is enterd. Can some one help.
Following is the code
IF ((event_name = 'WHEN-NEW-ITEM-INSTANCE')and (field_name = 'ASSGT.POSITION_NAME')) THEN
IF(name_in('ASSGT.SUPERVISOR_NAME') IS NULL) THEN
IF ( name_in('ASSGT.POSITION_NAME') IS NOT NULL AND name_in('ASSGT.ORGANIZATION_NAME') IS NOT NULL ) then
     l_sup := pop_sup.getPersonHierarchy(name_in('ASSGT.PERSON_ID'), name_in('ASSGT.ORGANIZATION_NAME'), name_in('ASSGT.POSITION_NAME'));
     fnd_message.set_string(l_sup );
     fnd_message.show;
     copy(l_sup,'ASSGT.SUPERVISOR_NAME');
     END IF;
END IF;     
END IF;

Kiran,
Note: if you are creating a VO just so you can turn around and use it in a data control, you could use the URL data control for your CSV data files.
Otherwise, http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadvvo.htm#sm0341, or if a JDBC driver exists for XLS, you could treat the XLS file like a database.
No, I don't have any examples ;)
