Fallback activation time for all VCC / all travel agents
When no activation time is sent via the channel direct integration, VCCs either get charged at a system-side fallback time (in case of Expedia, 6 am DOA) or at the time specified by the applicable rate group's payment policy.
We noticed that bookings via Expedia direct integration seem to not use the fallback if the travel agent is other than Expedia (like Affiliate, Egencia...) and revert to the regular payment policy. I suggest VCC payment fallback time to be tied to type of credit card (virtual vs. physical), or to integration type, or at least be set for all the minor sources as well.
The current solution is to set up individual rate groups for each channel/rate combination which clutters up your settings and may be prone to user errors.
