New Revenue distribution code - Billing Charge code not updating recurring invoice accounting distri

Recurring invoice is created using billing charge code 280ADM2 with the revenue distribution code as 0010028017. Bills are generated every year with the same distribution code. Due to reorganization, this year there was some change in the revenue distribution code and the user created new revenue distribution code as 0010083523 and added this to a new effective dated row for the charge code 280ADM2.
When the recurring invoice is generated after this change still refers to the old distribution code accounting chartfields. The billing charge code 280ADM2 is used by almost 800 recurring invoice.
