Will the forecast manual override in the worksheets will be erased after the analytical engine is r

Hi

I had run the analytical engine and the forecast is generated in the worksheets. But due to some variance we have maually changed the forecast numbers and saved.

Now if we run the analytical engine again, the manually changed forecast numbers remain the same in the worksheets or it will change according to the forecast generated by the engine.

please share some knowledge on this.
Appreciate your help

Thanks & Regards
