Hi,
Please refer an example:
Item AAA In-stock quantity 3, price 100 there will be posting between 01-01-2014 to 13-01-2014.
If you run above query, the result will be:
Bal : 3 ( Balance quantity as per selected date)
Val : 3 x 100 = 300 ( Value of the item)
0-30 days : 3--- means the above quantity is stock for 0-30 days.
In short, for a given date range, you are calculating balance stock, its values and duration of stock.
Hope you understand.
Thanks & Regards,
Nagarajan
