Error "Credit card number is not valid. Please check that all digits were entered correctly" when processing Sales Order that were generated from Web Store Orders even when payment method used is Invoice

This error is being encountered when:

1. Process a Sales Order generated from Web Store
2. Sales Order is billed via Transactions > Sales > Bill Sales Order.
3. Customer record have both:
   • Term assigned in the Financial > Terms field.
   • Credit Card number assigned under Financial > Credit Cards and Default Credit Card = T

Solution:

For customers who offer the options to use either Credit Card or Terms/Invoices as payment method during checkout. Ensure that the form assigned for Invoice Form field under Setup > Site Builder > Set up Web Site > Shopping subtab, is not the same with the Credit Card Form. Use or customize an Invoice Form not a Cash Sale Form.
