How to remove approved Purchasr Requisition in FIORI

Dear Experts,

Please help me how to remove approved PR in our FIORI. I tried to retrigger the release strategy but it came worst. It doubles the item in FIORI. Then in SBWP the status is ready. And found out the processer username was deleted in task id. I add again the username in task id but i get the same result.

I hope you could extend help.

Thank you,

Bev
