Currently, when the Accounting Category linked to a Rate is changed, this update is not applied retroactively to the existing Service Orders (reservations) created with that rate.
This means that if a rate was initially linked to the wrong Accounting Category, all existing bookings will keep the incorrect category, even after the rate setup is corrected.

Example:
If a rate was first linked to Leisure instead of Accommodation, and later the Accounting Category is fixed, the previous reservations still show Leisure and therefore report incorrect revenue data.

Request:
Please allow the system to automatically update the Accounting Category for all existing Service Orders when the linked Rate’s Accounting Category is modified.

Why this matters:

-Ensures accounting and reporting data consistency

-Avoids the need to cancel and recreate bookings to fix errors

-Reduces manual work and the risk of integration mismatches (e.g. with Optimand)

-Provides a more reliable data flow for connected systems and APIs

Thank you for considering this improvement!
