Ability to add new Requistion Line in Incomplete Requisitions

Summary:

I am not able to add a new line to the Requisition in Incomplete status.

Content (required):

I would like to know why Oracle has designed it in such a way that we are not able to add a new line to Requisitions in Incomplete status. We are able to duplicate an existing line. But we are not able to update the item.
