I need to be able to change case to current case owner's manager using standard manager ID field on User object. As shown in the screenshot below. Process Builder

I am getting following flow error every time flow executes and meet entry criteria.

This error occurred when the flow tried to update records: The flow failed to access the value for myVariable_current.Owner:User.ManagerId because it hasn't been set or assigned.. You can look up ExceptionCode values in the SOAP API Developer Guide.

I made sure that my manager lookup on user record is populated with value.

I have also tried creating formula field on case to get owner manager id and try changing owner with that id but I am getting the same error. Please note that I am system admin and have Manage internal user permission.

Can someone please help me resolving this issue?

  • when is this process builder running (on update or insert)? Is it possible there's no owner assigned which is the issue? You checked the user had a manager, but do you know what the value of the owner is on the case before this point? Oct 9, 2019 at 18:48
  • @KrisGoncalves This executes on update. And yes I assigned that case to myself. So I am the owner.

  • Well, I was going to suggest trying it using a formula type instead of field reference to see if you get the same error. I'd guess that it must somehow not be the value you're expecting - is there any trigger or WF update on owner that would run before PB? Oct 9, 2019 at 20:01
  • Yes I also tried using formula type within PB and same result. There is no workflow or trigger executes on owner field.

I've experienced this before where I swear process builder would throw an error on a related objects' field even though the field has a value. I included the post above to show this is not just something I made up.

I think a good test would be to (in a test environment), just create a formula field on case that includes the Manager ID of the owner of the case to confirm that process builder can change owner with a custom field on the same object without error. This way, you can isolate the issue to navigating through the related object.

Whether this is a necessary workaround, I'm not sure. It might be worthwhile to put in a case with Salesforce or test out activating the critical update concerning process builder and relationship fields (this is related to null values, but worth it in a dev box to give it a try to see if it helps).
