Delete Button is disabled in Check status

Hi Experts,

We are on SRM 7.0 . In Check status POWL, if the shopping cart is in 'Awaiting approval' stage requisitioner can only display the cart , we want him to able to delete the cart as well but the delete button is disabled.

We have assigned 'medium' level authorization in 'BBP_WFL_SECURITY' then the user can go into the details edit it and delete it..

But we want the 'Delete' button to be enabled on POWL screen. It is enabled if the SC is in 'Saved' status.

Any clues to achieve this?

Thank you,

Lavanya
