Error message
The selected Cost Unit is not currently active in Exact Online.Affected ERP integrations
Exact Online
Cause
This error occurs when the cost unit selected for an expense in Payhawk has reached its End date in Exact Online. When Payhawk attempts to attach the cost unit reference to the expense during export, Exact Online rejects the transaction because the cost unit is considered inactive or expired.
Solution
To resolve this issue:
Log in to your Exact Online account.
Navigate to Master Data > Financial > Cost unit.
Locate and click on the cost unit that is selected in your Payhawk expense.
Review the End date field.
Update the End date to a date in the future to reactivate the cost unit:
If the cost unit must remain active indefinitely, consider removing the End date entirely.
If the cost unit must only be active for a specific period, set an appropriate future date.

Click Save.
Return to Payhawk and attempt to export the expense again. The export must now be successful.
