Kanban receipt labor does is not created

I am testing Kanban receipt, I a have a method with and operation that as a production standard. When I do my Kanban receipt, the materials are backflushed as expected, but the labor does not. A time detail is created for the employee but with a time at zero. I checked the resource group and I have a labor rate. I am very confused that it does not work. Anyone had this problem?

I am seeking help from my Epicor friends.

Thanks in advance

I found the reason
