Relating child records to parent records has stopped working

Hello all,


I have an app currently in development that relates a lot of records using expressions in PowerApps. I've just added a new screen and realised that suddenly this has stopped working. For example, we have vehicle logs that are related to individual vehicles. The vehicle log has a parent record of the related vehicle. The data is in Dynamics 365/Common Data Service.


Below is an example which was working but now is not (I've taken out the additional fields):


Patch('Vehicle Logs',Defaults('Vehicle Logs'),{

Vehicle: First(Filter(Vehicles,new_registrationnumber = VehicleReg))

Hi @chris61 ,


Please explain what are "Vehicles", "new_registrationnumber" and "VehicleReg" referring to? Make sure that you all included connectors are connected correctly.
