Requisition Notification Customization in 11.5.10.2

Hi guys,

I need to add few columns to our existing Requisition Notification in 11.5.10.2

We has this customization in 11.5.7 and the way we did that time was to modify database package 'PO_WF_REQ_NOTIFICATION' which was called from Workflow.

Now we did the same change to 11.5.10.2 but the change in not showing up.

Can you please suggest me the steps to modify this notificaiton.

Thanks in advance.

Bobby
