DIW public guides for factories: ERP traceability design

The recovered public-source record states: DIW public guides cover several factory matters, including factory licences, boilers, gas activity and waste movement out of a site. It confirms only the described event, not that a company has obtained eligibility, approval, benefit or a compliance conclusion.

Define the trace object and end point. Use one actual equipment, activity or waste-removal flow to state which outcome must trace back to which source; searchable information is not automatically provable evidence.

For every node in guide source and applicability → obligation or process item → owner → licence or activity record → inspection and transaction evidence → exception → review, define a unique key, state, owner, effective time and evidence type. Append state changes rather than replacing the prior state.

Link master data, request or order, approval, transaction, attachment, accounting entry and external receipt in ERP. An interface should retain source ID, transmission time, result and retry record.

Route missing evidence, duplicate records, entity mismatch, reversed dates, and conflicting amount or quantity into an exception workflow. Correct through approval and reason codes, not by rewriting a summary.

Run one downstream trace and one upstream trace, then reconcile to operational records, external evidence and the ledger. Pass only when the chain is complete and signed-off differences are explainable.
