IDR Invoice Routing Issue

Summary:

IDR Invoice Processing Issue – PO Number Blank

Content (please ensure you mask any confidential information):

Hi All,

We are facing a recent issue with IDR invoice processing. Invoices with a PO number are processing successfully, even if the PO contains special characters like ".". However, when the PO Number field is blank, the invoice fails with errors such as INVALID QTY INFO and INVALID LINE TYPE LOOKUP.

Previously, invoices without a PO number were processing successfully, and we did not encounter these errors.

Could anyone please advise if there has been any recent change in IDR validation or configuration that requires a PO number? Any guidance on the root cause and resolution would be appreciated.
