My PunchOut catalog fails during testing with the following error message:

Cannot parse XML response.

SAP Ariba Catalogs

Some possible causes are the following:

• The time stamp is formatted incorrectly.
• The DOCTYPE element is missing from the Commerce Extensible Markup Language (cXML) PunchOut setup response.

For example, here is a response that contains both these errors:

<?xml version="1.0" encoding="utf-8" ?>
<cXML timestamp = "2011-11-21T06:44:52.6791797-05:00" payloadID = "2011-11-21T06:44:52.6791797-05:00">
<Response>
<Status code = "200" text = "success"/>
<PunchOutSetupResponse>
<StartPage>
<URL>http://www./URL>
</StartPage>
</PunchOutSetupResponse>
</Response>

Ensure you consider the following in your PunchOut setup response:

• The time stamp attribute must be formatted as: 2011-11-21T12:59:09-07:00
• The DOCTYPE element must be present.
