How to set up payment service for demo purposes (credit card processing)

Hello,

I'm trying to set up a payment service in AX2012 R2 (account receivable module) to demo the credit card processing functionality. When I use the 'Test connector' and try to set it as the default processor for new credit cards, I receive the following error: "Invaild property value for TestDecimal(21002)".

I need to set at least one payment service as the default, otherwise I cannot enter credit card information on a customer or sales order.

Does anybody have experience with setting up credit card processing for demo purposes and/or knows the solution for the error-message?

The following white-papers did not answer my questions:

- Credit card processing (MDAX 2012)

- Changes to credit card processing in MDAX 2012 R2

Thank you for your response in advance,
