00398: Central office code used where a specific office exists
What it means
SdI code 00398 means 1.1.4 CodiceDestinatario holds a public body's central office code, while the IPA register has one specific office of that body that can be identified for the invoice.
The usual cause
The central code is not used when the invoice can be addressed to a single identifiable office of the public body.
How to fix it
Look up the public body's invoicing office in the IPA register, or ask the body for it, put that office's code in CodiceDestinatario and send the file again.
