All feed clients need to make changes to their listing on their feed interface as the feed will always overwrite manual changes made on Private Property directly. Extending the expiry date of a listing is a change that has to be fed through to us.  If you are using Entegral, you can follow the steps below.

STEPS

1)  Open your expired listing on the OMS system

2)  Untick the Private Property box 

3)  Change the expiry date of the listing and make sure that the listing status is set to 'Active'

4)  Tick the Private Property box again and feed the listing through to Private Property.  All changes will update after about 30min.
