In order to find the reason for the OTA reservation not being in eRes the below steps need to be followed:

1. GDS Exception Report
The first step would be to look at the GDS Exception Report. Navigate to Tools -> System Administration -> Interfaces -> GDS -> Exception Reports.
- Next check the "Conf Nbr" column and the date the reservation was made to search for error messages.
- The Confirmation number is what eRes receives from the OTA's.
- To view the error message highlight the relevant message and click on the "View Detail" button. This view will stipulate the error details.
- Once the errors have been resolved the messages can be deleted.
