On customer and internal projects Work Package tab, we can assign resources according to their role (Activity Type previously defined). However, on the billing document, it is the material that appears on the billing item, and the materials have the same naming as the activity types (e.g. T002 senior consultant).
Additionally, if no Service Cost Level rate has been maintained, the system takes the activity cost rate for the bookings.
Does anyone know how these objects are linked and if we have access to manage the links between them?
Thanks in advance,
