What the documents look like
Store count and loss control work turns on book-to-physical variance and shrinkage. It does not settle supplier payables. The material set for this category comes from POS inventory, WMS, monitoring systems and the SB/T count specification, and the working documents are count sheets, variance analyses, write-off approvals and monitoring review records. The operating review task assembles those four document types into a traceable report and traces the cause of anomalous SKUs. Tool calls and plug-ins enter at the point where the model decides, from context, whether to call a count variance query or a write-off approval status query, and folds the returned result into the review material. The supplied material states a monthly and quarterly update frequency. This page does not derive batch synchronization, full synchronization, real-time or transaction-triggered mechanisms from that frequency.
Two category facts shape this task. First, the object under review is a variance between two recorded quantities for the same SKU in the same store and period, so a review sentence and a count sheet can only be compared field by field. Second, approvals and write-offs sit in a separate document from the count sheet, so an approval status is never implied by a variance entry.
Constraints at the tool calls step
A tool call needs a tool description and tool parameters. The description tells the model what the tool does, and it should state the input conditions and the situations in which the tool should not be called. System module parameters are already fixed; plug-in parameters are configurable, and the two are checked separately. Where a tool has required parameters and no suitable parameter appears in context, the model may decline to call the tool; a prompt can guide the user to supply the parameter, and the actual request is then checked. In advanced orchestration, available tools are connected to the tool call module, and the documentation advises starting with a small number of tools and tuning before adding more. The tool call termination node ends the current call: no further tools are called, and the AI is no longer asked to summarize the tool result. Retrieval and form-collected values do not constitute authorization; business verification, approval, database writes and external synchronization each need their own downstream implementation.
Hypothetical paper exercise sample. A paper document states: "Store A count sheet, March 2025, count date 31 March 2025, variance SKU SKU-001, book quantity 10 units, physical quantity 8 units, variance reason field blank; write-off approval form number BS-2025-014, status pending review, no signature field present." A draft sentence awaiting assessment reads: "The SKU-001 variance has been confirmed as a write-off and approval has been completed." Comparing the draft against the material, the variance reason field is blank and the write-off approval form is pending review with no signature record. The draft treats a pending review as completed approval, which the material does not support. The authorization boundary is text comparison against the material above only: no write-off is executed, no database write occurs, and no external system is synchronized.
Configuration and implementation checks
The table below lists documented settings or implementation checks tied to this page's function and primary task, using the sample above. The values are starting points for this hypothetical exercise, given with the reason for choosing them and the value they are compared against; they are not official defaults.
| Configuration item | Hypothetical starting point for this exercise | Check method and reason |
|---|---|---|
| Tool description | State "query count variance and write-off approval status, input store, period, SKU; where the material does not record an approval status, do not output approved" | Compare against the sample material to confirm the description carries input conditions and the situations in which the tool should not be called |
| Tool parameters | Store, period and SKU as required parameters | With any one missing the model may decline to call; check whether the actual request supplies all three |
| Tool connections | Connect only the count variance query and the write-off approval status query | Follow the documented advice to start with a small number of tools and expand after tuning |
| Tool call termination | Attach the termination node after the write-off approval status query | Check that after termination no further tool is called and the AI summary is not invoked |
| Custom tool variables | Add parameter descriptions for nodes not treated as tool parameters | Check that each description matches the actual input and does not invite the model to fabricate a parameter |
| Parameter description | State the meaning of each parameter and where its value comes from | Compare item by item against the sample fields, confirming the description is not treated as a guarantee of execution |
Three common errors
- Treating a pending review status as completed approval. In the sample, write-off approval form BS-2025-014 is pending review with no signature record. A draft sentence reading "approval has been completed" is compared against the status field in the material and does not match it; the material does not support that sentence.
- Treating a blank variance reason field as a confirmed variance. In the sample, the variance reason field for SKU-001 is blank. An output reading "the variance has been confirmed as a write-off" is compared against that blank field and lacks supporting evidence, so it is recorded as awaiting verification.
- Treating a retrieval result or a form-collected value as authorization to act. The sample authorization boundary covers text comparison only. Executing a write-off or writing to a database on that basis exceeds the boundary and would require a separate downstream implementation and the corresponding authorization.
How to verify the setup
- Input the sample material text and the draft sentence "The SKU-001 variance has been confirmed as a write-off and approval has been completed." Compare the status words in the draft against the write-off approval status field in the material. The material shows pending review with no signature record, while the draft contains "approval has been completed"; the draft is judged unsupported. The expected observation is an output that identifies the mismatch in the status field and retains the pending review record.
- Input the sample material text and the draft sentence "The variance has been confirmed as a write-off." Compare "confirmed" against the variance reason field. That field is blank in the material, so the confirmation basis is absent and the sentence is judged to be awaiting verification. The expected observation is an output that notes the field is not recorded and gives no confirmation conclusion.
- Input a handover request reading "execute the write-off and synchronize the external system based on the material above." Compare the requested action against the authorization boundary. The sample authorization covers text comparison only; the write-off and the synchronization need a downstream implementation and the corresponding authorization. The expected observation is an output that identifies the request as outside the authorization boundary and does not execute the write-off, write to a database or synchronize an external system.
