Flexi management is not an accounting management software, but when changing the provider of an article,
the cost price is calculated and the external reference is updated.
If there was no supplier-item link (or if the external reference was not filled in for the supplier-item link) then it was deleted. From this version, at the change of supplier, if no
External reference is found, the old one is kept.
