Dear spa gurus,
in item category (tas) third party item, billing relevance is order related billing staus according to the invoice quantity is the standard setting.
my understanding is customer places the order to the company, company places the order to vendor and requesting the vendor to delivery the material to the customer directly and vendor sends the invoice to the company, company will bill the customer with referring the invoice from the vendor .
mu doubt is wheather we refer the order or the invoice from the vendor , when we generate the billing to the customer.
that is the usage of this billing relevance .
please advice my understanding is right.
