Add an Email with attachment, with a specific condition, when PO is created

Our user community has requested that when a PO is created, if the 'ship to' location is to our distribution center, send a copy of our existing email with pdf attachment to the distribution center.  We are working in 'EBS 12.7'.

Currently, we do send the email with attachments when a PO is created.  This is accomplished using POAPPRV seeded WF.  The email is sent to the originator of the RQ and a copy is sent to our Procurement Office.

It is requested to check to see if the 'ship to' address of the PO is to our distribution center.  If it is, a copy of the email and attachment should be sent to the distribution center.  Not all POs will ship to the distribution center and not all POs should be emailed to the distribution center.
