How should EDI connect to my ERP?
Orders arriving as 850s should become orders in the operational system without rekeying, and invoices should generate 810s from the same records. The integration that causes trouble is the one where EDI is a separate silo exporting files a person imports, because the two then disagree about order status.
Middleware between an EDI platform and an ERP adds a place for documents to queue invisibly. An 856 stuck in a mapping error is indistinguishable from one never generated, until the chargeback arrives.
