What the documents look like
Warehouse picking and packing handles order outbound work. It does not handle supplier arrivals. The data sources named in the brief are the WMS, the order system, the electronic waybill platform and weighing equipment. Updates occur per order and hourly. The documents involved in operating reports and exception reviews are wave picking lists, review records, waybills and packaging consumable sheets.
The citation tracing step depends on how retrieved references are returned. According to the official knowledge base search node documentation, reference content is output as an array, and its length can be zero. Even when no content is found, the output path continues. This means an exception record in a report may correspond to an empty reference, and a person must check the original documents by hand. An empty array is not a business exception on its own.
Constraints at the citation tracing step
The knowledge base search node can select one or more knowledge bases that use the same vector model. Knowledge bases using different vector models cannot be associated together. The knowledge base identifier must be checked first, and those that do not meet the condition must be excluded. This same-vector-model requirement applies to the associated knowledge bases. It does not extend to industry registration sites or other external systems.
The minimum relevance setting is a filter threshold. It takes effect only in semantic retrieval or when result reranking is used. It is not a permission filter and does not separate entities. The dataset engine document states that this value filters out low-relevance search results. It does not exclude unauthorized warehouse records. Retrieval is not authorization.
The search output is passed to the answering step. Each answer must be checked against the cited original text. The thinking process shown by a model is not a substitute for source evidence. Whether a reference is adopted still requires review against the valid document version.
Hypothetical drill sample: A warehouse operations group prepares an exception review draft on 10 June 2025. The three source sentences are as follows. First sentence: "Wave picking list W-0610-07 was picked by picker A, completed at 09:12; review record R-0610-07 was signed by reviewer B at 09:40 confirming the quantity matched." Second sentence: "Waybill SF-0610-07 was printed at 09:45; the weighing equipment recorded a package weight of 1.8 kilograms." Third sentence: "Packaging consumable sheet M-0610-07 shows one medium carton was used." The draft sentence to be assessed: "This order has completed review and the packaging material matches the waybill, so it can be judged as a normal outbound." Two points need checking: whether "completed review" in the draft sentence is supported by the review record signature; whether "packaging material matches the waybill" is supported by a same-order-number correspondence between the waybill and the consumable sheet. Neither document states a comparison field between the waybill and the consumable sheet. That consistency is not supported.
Configuration and implementation checks
| Configuration item | Relevant setting or check on this page | Explanation |
|---|---|---|
| Associated knowledge bases | Select only knowledge bases using the same vector model | Check the knowledge base identifier; different models are not associated together |
| Reference content output | The reference array length may be zero | An empty array does not mean the workflow has errored and stopped |
| Reference input handling | Search output is passed to the answering step | Check each answer against the cited original text |
| Reference display check | Use a traceable sample to check the original text display | Do not replace source evidence with the thinking process |
| Document timeliness check | Test sources with the current version and a historical version | Whether a reference is adopted still requires review against the valid version |
| Minimum relevance | Takes effect only in semantic retrieval or result reranking | A filter threshold; does not perform permission isolation |
Three common errors
- Treating an empty reference array as a business exception. Input is the search node output
[]. The comparison object is the business exception judgment rule. The observable result is whether the downstream step marks the empty array as a picking failure. An empty array only means no content was found; the output path still continues. - Treating minimum relevance as a permission filter. Input is the minimum relevance setting value. The comparison object is whether unauthorized warehouse records appear in the retrieval results. The observable result is whether unauthorized records still appear in the references. This value only filters low-relevance results.
- Treating "completed review" in the draft sentence as fact. Input is the three source sentences in the hypothetical sample and the draft sentence. The comparison object is the review record signature field. The observable result is whether the signature confirming the quantity matched covers the full meaning of "completed review." A signature confirming the quantity matched and a completed review are different fields.
How to verify the setup
- Input the three source sentences and the draft sentence from the hypothetical sample. Compare whether "packaging material matches the waybill" in the draft sentence has a same-order-number correspondence field between the waybill and the consumable sheet. The observable result is that neither document states this comparison field, so that consistency is not supported and the evidence gap should be recorded.
- Input the search node output
[]and the downstream exception judgment configuration. Compare whether the downstream step marks the empty array as a picking failure. The observable result is that if the downstream step does not mark it as a failure, the handling is correct; if it marks it as a failure, the downstream rule needs correction. - Input the hypothetical sample sentence "review record R-0610-07 was signed by reviewer B at 09:40 confirming the quantity matched." Compare "completed review" in the draft sentence with the signature field. The observable result is that the signature confirming the quantity matched only supports the quantity check, not the full meaning of "completed review." That statement remains to be verified.
