3812003 - Error: Concur was unable to obtain a cancellation number for your hotel.This could be because you are outside the cancellation window or the hotel did not return a cancellation number in time

Why did I receive this message in Concur, but when I called my Travel Agency and the hotel they had the cancellation number?

Concur did not receive the cancellation number from the hotel so was unable to provide it to the user. , KBA , CON-CA-ADM , Administration , CON-CA , Cross Applications , CON-MOB-TRV-HTL , Hotel , Problem
