This error typically occurs when the brought forward period (e.g. b/f 202600) is not open. During the year-end rollover process, the system needs an open period to post the brought forward balances into. If that period is locked or not yet created, the rollover cannot complete.
How to resolve:
  1. Navigate to the Periods screen in your system.
  2. Locate the relevant brought forward period.
  3. Ensure the period is unlocked and open.
Once the period is open, you should be able to proceed with the year-end rollover successfully.
If you're unsure which period is required or need help unlocking it, please contact support for assistance.

Search for the period (hit the green dot to expose locked periods)



Highlight the period and click the three dots, then unlock.
