Hi @Steven Boardman,
I managed to remove the error. I added the template to the Change request an it now pulls in the start time and End time.
It has stopped pulling in the summary and description, i assume these are Service request variables? Is there a way to pull them in, i have had a look at the entity viewer on changerequest and i don't see a summary. there is h_disruption_level (Disruption Level) but that doesn't sound like the same thing.
thanks,
Sean
