Reading a purchase order is different from being authorized to create a sales order. A dependable document workflow needs controls between those two events.
Preserve the source
Keep a traceable relationship between the incoming document, the extracted fields, and the resulting business record. Reviewers need to see where a value came from.
Validate against business records
Check required fields and formats, then compare relevant values with authorized master data. A readable item description may still refer to the wrong item code. An extracted price may still require review under the organization’s rules.
Handle uncertainty explicitly
Missing values, duplicate orders, conflicting totals, and ambiguous matches should enter a visible exception path. Define who reviews them and what evidence they need. Do not silently substitute plausible values.
Separate recommendation from action
The intelligence layer can propose structured data. Business rules, permissions, and required human approval determine whether a downstream action is allowed. The system update is one controlled step in a larger workflow.
Design for recovery
Consider what happens when the ERP is unavailable, a request times out, or an update partially succeeds. Idempotency, clear status, and reconciliation help teams recover without creating duplicate business records.
This is an engineering approach to a reference workflow, not a claim of a deployed customer result.
