What the data for this category looks like
Yield rate and market data for solid waste treatment projects hosted by financial institutions mainly comes from internal project operation ledgers, local ecological environment department released disposal guidance prices, and third-party clearance settlement documents. The core data update cycle is daily. Guidance price data for some regions is updated weekly.
Most documents are structured tables, with each row corresponding to single-category single-day disposal data. Fields include solid waste category identifier, daily total disposal volume, unit total disposal cost, unit disposal operating revenue, daily net profit amount, month-on-month change amount, and others.
The unit of total disposal volume is tons. The units of cost and operating revenue are yuan per ton. The unit of net profit amount is yuan per ton.
What constraints do these characteristics impose on form and interaction
Data sources include internal project operation data and external public industry guidance prices. This requires the form to support multi-source data import and field verification, and meet the data compliance requirements of financial institutions.
The single-day data update cycle requires the form to limit single-batch processing to single-day data. Batch import across multiple days is not supported, to prevent confusion in data dimensions.
Fields include category identifiers and multiple numeric contents. This requires the form to bind fields to corresponding units, to avoid unit confusion during input.
The structured requirement for multiple fields requires the form to provide field mapping configuration, to adapt to differences in field names from different source documents.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DATA_IMPORT_BATCH_SIZE | 200 records/batch | The category coverage and detailed entry volume of single-day solid waste treatment data fit this batch limit, avoiding system overload |
FIELD_MAPPING_MODE | Custom matching | Field names of documents from different sources vary, requiring manual binding of core fields such as solid waste category identifier and total disposal volume |
DATA_UPDATE_CRON | 0 6 * * * | Matches the pre-update requirement for daily report broadcasting, ensuring that data from the previous day is finalized before 6:00 daily |
VALIDATE_FIELD_UNIT | Enabled | The units of solid waste data are tons and yuan per ton; verification can avoid unit confusion during input |
MAX_IMPORT_FILE_SIZE | 50 MB | Falls within the conventional size range of single-day solid waste treatment detail files, preventing parsing failures caused by oversized files |
PARSE_TIMEOUT_SECONDS | 300 seconds | Covers parsing time for large detail files, avoiding timeout errors mid-process |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test against your own samples before finalizing settings.
Three common mistakes
- Symptom: A
413 Request Entity Too Largeerror is returned when importing data. Cause: The imported file size exceeds the configuration limit ofMAX_IMPORT_FILE_SIZE. - Symptom: The solid waste category field does not load corresponding content when referencing knowledge base variables in the form. Cause: No field mapping rules are configured, and the solid waste category identifier field in the knowledge base is not bound to the form field.
- Symptom: The daily report data generated after form submission has inconsistent units. Cause: The
VALIDATE_FIELD_UNITconfiguration is not enabled, and the legality of units such as tons and yuan per ton is not verified.
How to confirm the configuration is complete
- Upload a single-day solid waste treatment data file, and check whether the automatically matched fields by the system are consistent with the actual data fields. Adjust the mapping rules manually if there are inconsistencies.
- View the scheduled task execution log to confirm that the task triggers and completes data updates at the preset time.
- Input test data containing non-compliant units, and check whether the system triggers verification interception.
- Import a small volume of test data, and check whether the number of imported batches meets the configured batch limit requirements.
