Months ago I added a triggerated Action to Task#Assigment to Change a Text Field on Service Request (Parent Object) and this works fine.
Now I tried somethine very similar: I want to update Targetdate on Service Request when TargetDate on a specific Task changes.
The ChildFold Expression I use looks exactly the same as for the Text Field update that works. But I get the following error:
Fehler bei Auswertung von expression.DataValue.PromoteToCommonType: unexpected second argument type: System.DateTime
Here is the Expression I use for Update Object Action as Value for Service Request TargetDate: $(ChildFold("ServiceReq#", RecId, "Task#Assignment", "$(TargetDateTime)", "+"))
any ideas whats wrong? are date/time filelds not supportet for childfold Expression?
In addition to the expression, here are some screenshots:
Expression: $(ChildFold("ServiceReq#", RecId, "Task#Assignment", "$(TargetDateTime)", "+"))
