Error on approval of PO approval notification

Hi All,

we are upgrading the PO approval work flow from 11i to R12(12.1.3)

we had recived the below error message on trying to approve the po Approval notification in R12(12.1.3 instance)

Error message # 3203 :Attribute NOTE_R does not exist .....( attaching error message)

We had identified the error and added the missing attribute to the PO_PO_APPROVE_PDF message .

Now when we try to approve the po the issue still exist , for this we need to open the workflow status monitor and query the po and perform RETRY process the each po.

Need a script which will perform the automatic retry process so that all pending PO can be approved with need to navigate to workflow status monitor and perform RETRY process.
