User receives workitem in his In Box and double clicks it to be taken to MIR7 screen. He then navigates to the Purchase Order and then to another invoice on that PO. Then he presses back button till he reaches Do you want to Park the Document Yes No pop up in MIR7. He presses no and then the work item disappears. What is expected is that the user decision option pop up is visible allowing him to decide what he wants to do with the workitem.
Please let me know if I have not been very clear. Any pointers will be welcome.
