How to use Credit Card in B2B

Hi,

We are using ECO 5 in a b2b scenario. I get this error

"No authorization carried out<br>Use another credit card or payment method"

when I try to create an order with payment type credit card or even Electronic check. Don't know what I'm missing.

I've checked all the settings in xcm, isauseradm and shopadmin but cannot find anything to turn 'authorization' on/off.

Is there is CC number for testing?

Any help is highly appreciated.

Thanks,

Rajiv.
