Update Bill from date to Active subscription from past date to sysdate

Summary:

We have a one time charges for annual billing frequency from Bill-from-date in 1st Jan, 2024. Since, AR period closed for previous months and only current months in active status. We tried to update Bill-from date to sysdate using Import Management. We are getting error to update the field. Also, we tried to update Bill-from date for Draft status Subscription. It's getting updated to sysdate but once we go to active subscription, we need to generate billing schedule. Once done, it will automatically update the Bill-from date back to existing date.
