Hi Shawn, Thank you very much the time given for your detailed response!
Yeah I can see the Dataverse table column is read-only while others are Read-Write. So guessed this wasn't the approach.
My next thought was to us the Fin & Ops Connector within PowerApps but you cant see the data to check if its read-Only or not and the Same Patch or form Update doesn't seem to work either
My 3rd option is to user power Automate but this requires the Object id but cant find any information on this and how to pass it in via PowerApps.
I Get this error.
Only 1 of 8 keys provided for lookup, provide keys for dataAreaId,WorkOrderId,WorkOrderLineNumber,ScheduleType,WorkerPersonnelNumber,MaintenanceAssetId,WrkCtrId,ScheduledStartDateTime.
Iv tried to satisfy with the fields by doing a Concatenate on all these fields and pass that into the flow then get this error,
Only 9 of 8 keys provided for lookup, provide keys for dataAreaId,WorkOrderId,WorkOrderLineNumber,ScheduleType,WorkerPersonnelNumber,MaintenanceAssetId,WrkCtrId,ScheduledStartDateTime.
When I check the flow run I think its taking the ',' in the Date format and thinking its 9 instead of 8

I feel I am so close.
Best regards
Paul
