Distribution Set field must be required when the line does not have an associated purchase order

Summary:

Hi Team,

We have a business need for the business that, when we add AP invoice line information, the columns listed below must be required depending if the line has a purchase order asociated:

Distribution Set

We need a personalization to make mandatory "Distribution Set" field, when the type line be "Item" and doesn't have associated a purchase order or when the line be "Item".

I did the follow expresion builder on inputComboboxListOfValues: Distribution Set

#{bindings.OrgId.inputValue == 300000003224307?true:false}

That works, but errors are generated when I select the Freight or Miscellaneous line type.
