Discover Credit Card

We have added logic to process Discover Credit Cards (Copy function group V21G, function module CCARD_CHECK_AMEX and modified it for Discover credit card processing.)

That is working fine, the issue now is that the Discover Credit card numbers are not masked in VA02.

Visa and Master Card numbers are masked with *********.

Any idea what I'm overlooking to get the Discover cards masked? Is this a BASIS function or something I overlooked in the code?

Thanks,

Allen
