Using MANDT in tables.

[Rick Sample]

We are creating tables for a new application. While some of it 
should have gone directly to ABAP like creating the DB (tables) 
and programs.
 
We created some tables with MANDT and was asked why we decided to use 
MANDT in our tables. 
 
Not sure if this was a trick question so I need to ask why wouldn't we 
want to use MANDT? 
When I created a new Business Object it checks for Mandt by default. 
 
Pros / cons?
