At the last screen of booking a flight, it asks me to enter the frequent flyer number, whereas I had already selected a correct one there.
Original Error Message:
@keremakguen I take it you double-checked the number you have entered on your SAP Concur travel profile, correct? For some reason the system isn't recognizing the number you have listed on your profile. Maybe delete it and then re-add it to your profile.
@Martin71 did you receive this message while trying to book a flight in Concur Travel?
