How to verify that at least 1 record is entered in a portal

[Normand]

I have a Contact layout (table Contacts) which also displays a portal (table ContactTypes) allowing the user to enter many contact types for a Contact. I need to make sure that at least one record is always entered by the user in the portal for each contact that is created or modified. Where should I put this validation on the Contact layout, and what would be the commands ?

Similarly, I would need to create a script that would scan all Contact records, and create a record in the portal (ContactTypes) for this contact if none was found. The new record created would be assigned a static contact type value (ex: "General").

Thanks

You can check if there is a record in portal with IsValid () function and to check if there is only one or more records you can use Count () function.

You could also use the IsEmpty(RelatedTable::RelatedField) Function.
