Adding new field in DSO and CUBE without deletion of Data

Hi to all,

I have one scenario; please can any one tell me the solution for that.

Example: I have enhanced the standard extractor with field A, and I have replicated the datasource to BI production system.

But my DSO and CUBE already contain the data in Production system and I can’t delete the data from DSO and CUBE, due to huge amount of data.

Now I want to add new field A in DSO and CUBE with out deletion the existing data from DSO and CUBE, so that old data comes with new field data.

How to do that in production system, and without deletion of data, is that practically possible.

if it is possible, does it will Corrupts the delta initialization in DSO.

Please can any one share some light on it.

I shall be thankful to you for this.

Regards
