A package can be linked to a vendor A title can be linked to a package, and this link has those properties : vendor, start date, end date, proxy So it is possible to link - packageA with vendor1 - titleX with packageA AND with vendor2 => what would be the "right" vendor associated with titleX ? It seems strange Maybe the vendor should only be defined at the package level ?
I see that vendor can also be defined at agreement level. I am lost...
