Date cannot be within the period / end of year lock date:
The date being set for the Xero 'Purchase Bill' that was created for this expense report is within the specified lock date set on Xero.
It means that the date being set for the 'Purchase Bill' on Xero for this expense report is within the period and/or end of year lock date set on Xero.
The date used for the 'Purchase Bill' is controlled by the 'Purchase Bill date' setting in the Xero integration configuration. Refer to the Xero integration guide on how the 'Purchase Bill' date is set when an expense report is sync'd with Xero.
Once a lock date is set on Xero, 'Purchase Bills' that are dated on or before the lock date are not allowed to be created. This results in a sync failure for the expense report in question on Travelstop.
You can resolve this error by following these steps:
You can change or remove the lock date set on Xero by following the instructions mentioned here.
