What does GR-R-001-4 mean? When Supplier is Greek, the Invoice Id third segment must be a positive integer
Why did my invoice fail GR-R-001-4?
For Greek suppliers, the third segment of the Invoice number must be a positive integer. This segment carries a numeric component of the Greek composite invoice identifier (such as the branch/installation code), and non-numeric, zero-padded-invalid or negative values break automated parsing.
