Preference rule remains active for procurement information

Preference rule indicates the preferred option when there are multiple purchase data from the same supplier.

For example, if there is a purchase data per unit and a purchase data per box, it is possible to purchase both per unit and per box. The checkbox 'Preference rule' then indicates the preferred option when making a purchase.

If there is only 1 purchase data from a supplier, that is always the preference, because there is no other purchase information that could be preferred. In that case, it is not possible to uncheck the preference rule.

There is 1 rule per supplier which is the preference rule.
