Issue In Stock Transport Order

Hi Friends,

I am facing the below issue and need your help

Purchase order created(Stock transport plant to plant within same co.code)

Goods Issue done from supplying plant for Qty-12  and when the user does the goods receipt for the same qty he gets an error

"PL Stock in transit exceeded”, even not able to cancel the GI of the same(error is the same).

and this is happenning in one particular plant and one material.

I could see there is stock in transit(MB5T)for the same material,Qty,and plant.

Note : When replicated the scenario in qulaity environment this issue doesn't exist.
