Field help (EECFLOPHY) 

This field is used to specify whether the line identifies a physical flow playing a role in the Customs document file statement. An invoice line not linked to a physical flow can be declared for regulation if an EEC rule and/or an EEC transaction nature is entered on the invoice (Customs information option).
The initialization of this field is carried out differently whether it concerns a product managed in stock or not:

1/ Product managed in stock

2/ Product not managed in stock
