Hi ,
Yes, Suman & Vinod are right to the point but to add few things with that :
If you are adding new object to an MASTER DATA then after added before moving to different land scape plz make sure to delete the data from the Target systems(i,e P,M,tables).
Coz the structure is gonna change so it might fail in the target systems.
Moreover you will be be doing a full load again to get historical data for newly added fields so it wouldn't be a problem,just you need to confirm if have the authorization to delete MASTER DATA or not.
Thanks,
Bobby
