What This Category of Data Looks Like
Warehouse logistics ledger data mainly comes from Warehouse Management System (WMS), paper inbound and outbound documents, handheld terminal PDA scan records, and transportation positioning data. Data updates are triggered by business nodes, and are updated in real time after inbound, outbound, or inventory count operations. Some batch ledgers are summarized and updated on a fixed cycle. A single ledger entry includes fields such as material code, material name, specification/model, unit of measurement, inbound/outbound time, inventory balance, batch number, and operator. Batch summary ledger documents integrate business data from multiple days or batches.
What Constraints These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering
Warehouse logistics ledger data is scattered across multiple business systems and updated in real time with business nodes. This requires multi-turn dialogue to gradually guide users to clarify the query business cycle and material scope, to avoid calling irrelevant data. Ledger fields include specific units of measurement and business identifiers. Prompts must explicitly require outputs to strictly match field names and units, to prevent unit confusion or missing fields. Batch summarized ledger data has a large volume. Multi-turn dialogue must support batch pagination recall of data, to avoid overloading a single context. The real-time update feature requires reading the latest dataset snapshot first when each dialogue is triggered, without using fixed cached historical data.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Set to {"target_warehouse": "specified warehouse code", "query_period": "last 30 days"} | Clearly define the query subject and time range to filter irrelevant business data |
messages | Set the initial system prompt to "Only generate summary reports based on uploaded warehouse ledger data, strictly match field names and units of measurement, gradually confirm unclear query conditions during multi-turn dialogue" | Restrict model output boundaries, ensure only the provided ledger data is used, avoid generating irrelevant content |
| Maximum context length | 8000–12000 characters | Single batch summarized ledger data can reach thousands of characters, reserve sufficient space for multi-turn dialogue history context and current query |
| Single data recall limit | Top 15 entries | Balance data completeness and context load, avoid processing timeouts caused by passing too much data at once |
chatId | Bind user-specific session identifiers | Ensure conversation records of different users are isolated from each other, only display interaction content from the current user |
Three Common Misconfigurations
- Issue: In shared public applications, unauthorized users can view other users' conversation history. Cause: No independent
chatIdassigned to each user, resulting in unisolated session data. - Issue: After calling the "get conversation record list" interface, the returned message sequence cannot distinguish the corresponding relationship between user questions and AI replies. Cause: Did not match message roles and content according to the order of the
messagesarray, or did not carry the correct session identifier to filter data. - Issue: The global variable value passed in for the first time can be displayed in two components, but the model cannot modify it to a new value during dialogue in the same scenario. Cause: The prompt did not explicitly require the model to update global variables, or the editable permission of variables was not enabled in the configuration, preventing the model from triggering variable updates.
How to Verify Proper Configuration
- Launch a test dialogue, specify a specific warehouse and time range, check that the generated report only includes ledger data within the corresponding range.
- After sharing the application, launch a dialogue using two different accounts, check that each account can only see its own conversation records.
- Call the "get conversation record list" interface, verify that the order of user messages and AI replies in the returned
messagesarray matches the actual interaction. - Try to request modification of global variables during dialogue, check that the variable values are updated as required and applied to subsequent report generation.
