What this category's data looks like
This page focuses on the deployment, operations, and application handover of laboratory hazardous chemical procurement and ledger management. The materials come from three types of paper or electronic forms: hazardous chemical procurement applications, usage registration, and inventory ledgers. The update cadence follows each procurement, usage, return, and inventory count. Field characteristics include product name, specification, quantity, date, handler signature, and receipt number. After deployment status and operation records enter the conversation record interface, procurement applications serve as the demand source, usage registration serves as the consumption basis, and inventory ledgers serve as the balance baseline. The three are pulled as a message list by application and session dimension, for manual or external systems to register, export, and review accordingly.
Configuration and implementation checks
This step is executed by the conversation record interface (by application and session dimension), outputting a session message list and total record count, including role and reference information. The handover-ready deployment status and operation records are then completed by manual or external systems. The message list is not a version ledger of business materials; it serves only as conversation evidence for registration and review.
| Object | Check | Verification action |
|---|---|---|
| Hazardous chemical procurement application | The same product name, quantity, date, and signature in the application form and the ledger are consistent | Retrieve the procurement application form, compare it item by item with the ledger records by product name and date, and check whether signatures and receipts are complete |
| Usage registration | The deduction quantity, usage date, and handler in the usage record are consistent with the inventory ledger | Check the registration book by usage date, verify the deduction quantity against the ledger balance, and inspect the user's signature |
| Inventory ledger | The ledger balance is consistent with the summary of procurement, usage, and return, and the version is synchronized | Verify the balance by inventory count date, compare the procurement and usage summaries, and confirm that the ledger version matches the handover form version |
| Conversation record interface output | The total record count matches the pagination offset, and role, reference, and time are queryable | Pull pages by chatId, verify the dataId and value fields, and confirm total and response code of 200 |
Three common errors
- Symptom: The name, quantity, and date of the same hazardous chemical do not match between the procurement application and the inventory ledger. Cause: The two materials are registered separately, not compared item by item against the same record, and only totals rather than details are checked during handover.
- Symptom: The usage registration and the ledger deduction quantity are inconsistent, and signatures or receipts are missing. Cause: The ledger is not backfilled in time after usage, the handler omits a signature, and receipts are not archived, so the record cannot be closed.
- Symptom: The deployment status and operation record versions are not synchronized, and the handover form is missing items. Cause: Records are not updated after the application and session identifiers change, only the first page is fetched during pagination, and reference and elapsed-time fields are not verified.
How to verify the setup
This feature's acceptance: page through all records by total, sample one record to verify role, reference information, and time, confirm response code of 200, record the array item count separately, and verify reference text tokens separately.
Business test: check item by item against the handover form once, see which record is missing, and focus on verifying the fields, dates, and signatures of the procurement application, usage registration, and inventory ledger.
- Pull the session message list by
chatIdwith pagination, pull two consecutive pages and compare total and offset, and confirm the record counts are consistent. - Open one record to verify
dataIdandvalue, and check whether the role, reference, and elapsed-time fields are complete.
