Hi All,
we are trying to setup substitute approval in our project for first, clients were not using this till now. we have added Approver A as substitute for approver B. we can see that Shopping carts are displayed in work overview of both users, but only actual approver is able to approver. And when we try to approve the cart from Substitute approver opening the cart we get "Work item not or no longer valid (might have been already processed)" error and when we try to approver it from preview it gives following error /SAPSRM/CX_PDO_WF_MODE_BAN Work item not or no longer valid (might have been already processed) ....
please help...
