Invalid link when clicking on Go To Receiving in cloned instances

Hi.

We are encountering an issue where the 'Go To Receiving' link is not working in a cloned instance.

The link it is trying to go to is :

http://XXXXX.corp.XXXXX.com:8000/pls/FNDBA/OA_HTML/OA.jsp?OAFunc=ICX_POR_LAUNCH_IP&porOrderHeaderId=97560&porMode=confirmReceipt&porRequesterId=2855&porExpectedDate=26-MAR-2013&porOrderTypeCode=PO&porDestOrgId=81&NtfId=501596&transactionid=678194737&oapc=14&oas=aYYcE41zeiJIYYZ_WTNy5w..

If I remove the /pls/FNDBA where FNDBA is the R12 instance and give it an address as such, I can get to receiving.
