Physical Inventory

Hi All

On the Item master. On hand form there are two feild

Physical Inventory

Available Physical

What is thedifference between two. WHen i am generating the "on Hand Inventory" and "physical inventory by item dimension" reports in"on hand inventory" under "available physical" the value is 16750.But on "physical inventory by item dimension" report under "on hand" it is showing 21750 and under picked it is showing 5000. This 5000 value i found on the SO which is at the status picked and the qty is 5000.

 thanks
