We are aware of an issue around EDI file conversation that impacted four suppliers invoices being generated as back orders instead of pairing to the original order ID.
The transmission issue has now been resolved and invoices are generating as expected since Thursday, we have identified a list of back orders impacted and these may need to be cancelled off to avoid duplication, if you notice unexpected back orders or have any concerns, please reach out to support for a list of impacted orders, sites & suppliers.
