Org Structure creation for different countries

Hi,

Pls guide me as of how to proceed with the scenario.Client has Organization structure in 2 countries,that is India and srilanka.

1/ While configuring in the system for creating Org structure should i change the MOLG value(in SU3)accordingly for each Country?

2/ India business head and srilanka business head reports to Group MD who sits in Malaysia where there is no Org structure.So how do i maintain this reporting.I mean should i create a Org unit in Malaysian Country grouping.Will this work?

pls guide me

Thanks
