Replace the workitem while executing

Hello Everyone,

I am sending a workitem for the release of PO to multiple approvers at a time. As per the process, If one of the approver starts executing the workitem, the others will not be able to do so.

If the approver who executes the workitem first is not going to release the PO, but just comes back from the ME29N screen. Now the workitem wd be reserved for the approver and the others will not be able to do anything. Only this approver will have to release the PO. My requirement is to replace this workitem so that the other approvers can release the PO.

Is this feasbile or not.... I have tried to do the same using the function modules in the method SINGLERELEASE which is used to release the PO. But was unable to get the result.

Please do help me out.

Thanks,

Samson
