But, what about the historical data?? Can we think in a remodeling process that allow us to complete the old records with this new field without thinking of deleting all, neither doing a initialization?
A remodeling process is used when you need to fill a new field with a value/formula based on data that's already available in your InfoProvider. Since you don't have 0MATERIAL in it yet, I think it's safe to say remodeling is not an option for you.
That doesn't mean you need to delete all data if you're very careful. You could work with full repair loads (if you can assure you can easily identify all historic records for which you need to add the value of 0MATERIAL). That process is (in my opinion) a whole lot more complicated than a new init/complete reload, but it could be possible...
