Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Decision and scope
Missing source records need an explicit operational state. Distinguish not received, rejected, incomplete and awaiting reconciliation. Do not silently convert absence into zero or present the last known value without its age. Define who investigates the exception and which calculations must remain provisional until it is resolved.
Illustrative example
Illustrative example: the shift record for one production line has not arrived. Its output for that interval is marked unknown, while the previous measurement remains visible with its timestamp. A task is assigned to the source owner. The plant total declares partial coverage rather than appearing to represent every active line.
Acceptance check
Test late arrivals, duplicated submissions and corrections after reporting closes. State whether historical reports are recalculated. Accept the handling when users can distinguish missing information from actual results and follow each exception through resolution.
Key takeaways
- Accept the handling when users can distinguish missing information from actual results and follow each exception through resolution.
