Adding characteristic to an existing DSO
I need a clarification in adding objects to an existing DSO.
I want to add 2 characteristics one as key field and other one as data field in DSO that is existing. The characteristics are not present in the DSO now.
This DSO in Production system has millions of records in it.
So my questions are
1. Is it possible to add info objects to the existing DSO?
2. Even if I am able to add, due to millions of records in production systems for this DSO will there be any problem while transports?
We are using BI 7.0
