We have a request of changing the GL Account for a service. Now we have the same GL accounto associated to a Valoration class but all services created use the same Valoration classs, and we need to create a new validation class with an specific GL Account. We now Valoration and GL accounts are related to materials not services. Can you help us to create a new Valoracion class and GL account for a service? we create a new service with a valuation class as we show on the next image, but the system is not using it, it always uses the valuation class with no value. ¿Can you tell us how can we change this?
