What this category's data looks like
In the scheduling and class consumption scenario of training institutions, the materials entering the data version and change maintenance function include: class schedules, class consumption records, schedule adjustment applications, as well as the version ledger and change records themselves. The class schedule is the current version carrier of the scheduling result, the class consumption record is the proof of actual consumption, and the schedule adjustment application is the source of change; the fields, dates, and signatures of the three must be consistent. The material sources are academic affairs system exports, manual reporting, and external system callbacks; the update cadence is triggered per class session or per day, and when changes occur, the old version must be retained and traceable. The class schedule focuses on course, class, teacher, and time slot; the class consumption record focuses on student, class session, consumed quantity, and signature; the schedule adjustment application focuses on the original class session, target class session, approval, and receipt. When these materials enter the HTTP interface and external system stage, each serves as the data source for the request body or path parameters, sent by workflow nodes according to the convention, and the response body and returned fields then return to the version ledger and change records, used to determine that the current version is unique, the old version is traceable, and references are synchronized.
Configuration and implementation checks
This step is executed by the HTTP node in the workflow, outputting the response body, status code, and returned fields. The version ledger and change records are parsed from the response by subsequent nodes, or the external system processes them according to the convention to complete the follow-up. The HTTP module sends requests to the target address; path parameters, request body, and request headers can all use variable placeholders, and the variables come from global variables, system variables, or the output of preceding nodes.
| Object | Check | Verification action |
|---|---|---|
| Class schedule | Course, class, teacher, time slot, and date must match the class consumption record and schedule adjustment application item by item; the version number must be unique and the old version traceable | In the request preview, view the complete rendered address, check the path parameters and request body fields, and confirm that the placeholder variables resolve to actual values |
| Class consumption record | Student, class session, consumed quantity, date, and signature or receipt must correspond to the class schedule and schedule adjustment application; the same record must not have inconsistent name, quantity, or date across two materials | Check the request header names and value sources; authentication information must be passed in according to the external system's requirements; compare the returned fields with one sample request |
| Schedule adjustment application | The original class session, target class session, approval status, and receipt must be synchronized with the class schedule and class consumption record; after changing one content item, references update synchronously | In the variables panel, check the source of each placeholder and confirm that the variable comes from a global variable, system variable, or the output of a preceding node |
| Version ledger and change records | The current version is unique, the old version is traceable, references are synchronized, and the change records include the fields before and after the change and the signature or receipt | Compare the response with one sample request and check whether the version number and reference fields in responseData are updated synchronously |
Three common errors
- Symptom: The name, quantity, or date of the same class consumption record does not match between the class schedule and the schedule adjustment application. Cause: The materials are maintained separately, changes are not written back, and versions are not synchronized.
- Symptom: After changing one content item, the version number does not change, and the old version reference still points to the old content. Cause: The version ledger is not updated, and reference synchronization is missing.
- Symptom: The schedule adjustment application lacks a signature or receipt, and the class consumption record has no corresponding proof. Cause: The approval step is not closed-loop, and the external system does not call back according to the convention.
How to verify the setup
Preview the rendered request, check the status code and returned fields, then compare the result against one sample; confirm that Authorization is passed in according to the external system's requirements, that each placeholder in variables can be traced to its source, and that responseData contains the version number and reference fields.
Business test: change one content item and see whether the version number and references are updated synchronously.
- In the request preview, check the complete rendered address, request headers, and request body, confirm that the placeholder variables resolve to actual values, and that authentication information is passed in according to the external system's requirements.
- In the variables panel, check the source of each placeholder, confirm that the variable comes from a global variable, system variable, or the output of a preceding node, and compare the returned fields and version ledger with one sample request.
