I found the product move in product template view and I check with product move for each location. I filter with source location and destination location of one particular location and get the 25 quantity. But When I check with this location in on hand quantity ,on hand quantity is 20. I think that must be the same,right? What situation make not equal. When I check not for every product, some product are equal and some product are not equal.Why? Welcome for any opinion.
