I am writing punchout support for a number of SAP OCI Customers.
I have the 2003 SAP OCI Guide (has anyone got a link to a more current one.)
Looking at the contents - it seems pretty straight forward. One thing is not tpo clear however is how I should handle a rejection.
for example the intial incomming request for a catalog contains user and password etc and can be either a HTML Post of HTML Get.
so if they have an invalid password or a service isnt available then what do I do?
Do I redirect tem to my own error screen? or try and return them so status codes?
