Hi gurus,
We are trying to add new dimensions to an already existing model that has been in use for 4 years now and I am wondering what are the precautions we need to take before we go ahead.
The new dimensions capture new set of data but the new reports we will be creating will capture the old data and the new data.
Should we create a new model altogether and copy the old data to it or should we just add the dimensions to the existing model?
Regards,
David
