Stock ageing

Hi all!!!

I have made a stock ageing report based on the current location of stock e.g. if I bought a stock of 300 kgs on 1/April/2019 and it is transferred on 05/Nov/2019 it shows the ageing as 0D on the current date and location, but I want the ageing from 1/April/2019 irrespective of how many times it has been transferred.

Any kind of help would be much appreciated.
