Supply Plan not decrementing qty on a component pick move order

Content

Hello,

We have on-hand of a certain part for 5.Move order was generated to pick this part to be eventually issued to a WO(the issue has not been done yet). In Supply Plan(SP) when we run collections and then the plan we still see on-hand qty of 5 and not 1 since 4 of the on-hand are reserved against the WO.

We have enabled reservations in the plan options and  move order requests were also collected in the collections along with on-hand and WO supplies so not sure SP why collections and SP continue to show on hand as 5 instead of 1.
