I get this error when I tried to check in an inbound TU
The transportation unit has a related provisional appointment in SAP Dock Appointment Scheduling. Arrival at checkpoint cannot be posted for a TU with a provisional appointment in SAP Dock Appointment Scheduling.
I am not using Dock appointment schedule.
I debug and found the error due to checking the status of ISR38 and see if the status is not active. Please advise me
