What this category of data looks like
Data for this category primarily comes from procurement systems, supplier quotation documents, budget sheets, and contract systems. Daily associated documents include purchase requisitions, price comparison records, formal contracts, and acceptance receipts. Data updates follow individual procurement workflows, with updates and archiving completed after the full workflow runs from application to acceptance. Fields typically include purchase order numbers, supplier qualification numbers, contractually agreed amounts, acceptance completion times, and more. There is no unified mandatory format, and it adjusts based on internal enterprise workflows.
What constraints these characteristics impose on the HTTP Interfaces and External Systems link
This page is written based on the configuration logic of FastGPT v4.17.0. Data for this category is scattered and has inconsistent formats. It requires HTTP interfaces to support flexible field mapping, and conversion rules for fields from different sources can be passed via variables. Data updates follow individual procurement workflow cycles, so interface call frequency does not need to be high. The setup can adapt to low-frequency batch synchronization requirements. The need to synchronize multiple types of documents requires interfaces to support metadata binding for different documents such as purchase requisitions and contracts. Failures directly affect procurement progress and compliance, so interfaces must have clear failure callbacks and retry mechanisms to ensure the stability of the data synchronization link.
How to configure settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {procurement system-specific API key} | Complies with the identity verification rules of the procurement system to ensure legitimate interface call permissions |
variables | {"purchase order number": "${external.purchase_no}", "contract amount": "${external.contract_amount}"} | Adapts to field mapping requirements for multi-source data, unifying the format of business parameters received by the interface |
responseData | {"status": "success", "purchase_id": "${local.purchase_id}", "timestamp": ${current_time}} | Matches the response format of internal enterprise systems, facilitating quick identification of call results during troubleshooting |
| Interface timeout period | 600 seconds | Adapts to the low-frequency call rhythm of individual procurement workflows, avoiding timeout interruptions caused by large volumes of business data |
| Retry trigger threshold | 3 consecutive failed calls | Balances data synchronization reliability and system resource usage, avoiding ineffective retries |
| Document upload size limit | 1000 MB | Adapts to the maximum size requirements of documents such as procurement contracts and acceptance slips, avoiding synchronization failures |
| Batch synchronization batch limit | First 20 entries | Adapts to the number of documents in individual procurement workflows, avoiding excessive data volume in a single call |
Three common misconfigurations
- After calling the interface to complete knowledge base creation, the target procurement management application cannot be associated, and the returned associated fields are empty. Cause: The purchase order ID was not bound as knowledge base association metadata via
variables, causing the system to fail to identify the business ownership. - The API call returns a 514 status code. Cause: A valid
Authorizationparameter was not configured, or the key expired without being updated, triggering permission interception by the procurement system. - A timeout error occurs when synchronizing procurement documents in batches. Cause: The interface timeout period was set too short, failing to adapt to the processing duration of multiple documents in a single batch.
How to confirm the configuration is correct
- Call the test interface, pass simulated purchase order data, and check whether
responseDatareturns field content that meets business expectations. - Verify the validity of the
Authorizationparameter, call the public verification interface of the procurement system to confirm that permissions are normal. - Submit a batch document synchronization task, observe the interface response duration, and adjust the timeout period to meet the actual needs of the current business.
- Check the knowledge base list to confirm that the created knowledge bases have bound the association identifiers of the corresponding procurement management applications.
