IRR_NOM_F: File name not valid
What it means
PPF reason IRR_NOM_F means the name of one or more files in a delivery to the PPF does not follow the naming rules.
The usual cause
For invoice data (F1) files the name must be <profile>_<file name>.xml, the profile being Base or Full. Chorus Pro also refuses the characters % $ ! & / \ : ; « » # @ and names longer than 256 characters.
How to fix it
Rename the named file to the naming rules and send it again.
