ERROR at Transfer Journal Process

Hi All,

Can you plz help me out to resolve this ERROR

When i am doing the Transfer Journal Process at the time of Posting(Note: Adv Warehouse Management was Applied)

"20 cannot be picked because only 0 is/are available from the inventory"

and is there any other process, where i am missing before validating & Posting

Have you checked on hand inventory of the item.

Do you have enough inventory in the from dimensions?
