Hardcoded Messages PO_PO_APPROVE in Forward Documents form.

Hello,

We have a situation where we needed to create a new branch inside the Notify Approver Subprocess.  If the PO contains a specific value in the po distribution, we need a message sent to the approver with details that include, say, ABC in the body of the message.   When the PO doesn't contain a specific value in the po distribution, we need a message sent to the approver with details that include, say, DEF in the body of the message.

Since Oracle only has messages for approvals:  PO_PO_APPROVE, PO_PO_APPROVE_PDF, and PO_PO_APPROVE, and PO_PO_APPROVE_PDF_OAF, we needed to create our own messages.
