Hi experts!!!
I am going to load new master data in our BI.Our BI consists of some cubes and DSOs which have data from past 3 years and which are based on old master data.Now the Master Data is completely changed to new values and will be loaded into our BI.I have following doubt regarding this:
From past three years the transaction data that is loaded into our cubes and DSOs is based on Old Master data.Now if I suddenly load NEW master data values,what will happen to this old transaction data loaded until today?I can imagine that once I load new values,from now onwards,transaction data will be based on new values only.The question is what will happen to the old transaction data ?
Please assume both cases of Time Independent Master data and Time Dependent Master data while reading my question.
Thanks for your time.
