XML Cannot Import New Record

I have an export/import routine.

It can export all record.

It can import existing records to modify them.

It blows up when it tries to import a new record.

It says “Salesperson/Purchaser” does not exist. Code = “036”. The only place this value appears is as the Code for a new record.

Maybe this is a trigger from somewhere else in the system?

I can go into NAV and manually enter the record.
