What data for this category looks like
Packaging and printing yield and market data comes primarily from enterprise ERP systems, production work order ledgers, raw material procurement ledgers, and terminal order quotation systems. Data updates once daily, generating a T+1 daily report after that day’s production ends. Document formats include structured Excel work orders (each often contains multi-device batch data), PDF production daily reports, and structured API-exported device operation logs. Core fields include order number, product model, printing format, per-sheet production cost, factory settlement unit price, delivery quantity, and raw material usage. Units cover multiple measurement standards such as square meters, kilograms, yuan per piece, and meters.
What constraints these characteristics impose on workflow orchestration
Data sources for packaging and printing are scattered and have inconsistent formats. Workflows require frontloaded multi-source data adaptation nodes to handle imports of different formats and field mapping. Data updates once daily on a fixed schedule. Workflows require configured timed trigger mechanisms to match the business’s daily report generation cycle. Single documents often contain tens of thousands of rows of batch data. Workflows require support for large file chunked parsing and batch loop processing to avoid single-run timeouts. Fields with multiple units of measurement require workflow configuration of unit conversion nodes to prevent unit confusion during yield rate calculations. Additionally, production processes include multi-level relationships between work orders, batches, and equipment. Workflows require support for multi-level loop orchestration to achieve layer-by-layer data summarization.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Packaging and printing work order ledgers often contain tens of thousands of rows of device batch data, requiring adaptation for large file upload and parsing needs |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing large Excel or PDF documents requires longer processing time to avoid mid-run interruptions |
maxLoopDepth | 3 levels | Packaging and printing production processes have three levels of relationships between work orders, batches, and equipment. Limiting nested levels prevents execution errors |
chunkSize | 800–1200 characters | Product model and format description text for packaging and printing is often long, adapting to chunked parsing and context transfer for long texts |
workflowTriggerType | Timed trigger (daily 08:00) | Matches the T+1 generation schedule of packaging and printing yield rate daily reports to enable automated daily report output |
outputFilterMode | Only retain final node output | Only return the final daily report summary result, filtering redundant content from intermediate AI interactions |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material formats, data volumes, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Symptom: Workflow executions return
413 Request Entity Too Largeerrors. Cause: TheUPLOAD_FILE_MAX_SIZEparameter is not adjusted, making it impossible to load Excel work order data with over 15,000 rows. - Symptom: Nested limit exceeded errors occur after loop execution. Cause: The
maxLoopDepthparameter is not restricted, with incorrectly configured nested loops of 4 or more levels for work orders, batches, equipment, and teams. - Symptom: Generated daily report files retain intermediate AI question-and-answer reference markers. Cause: The
outputFilterModereference shielding rule is not configured, and residual context from intermediate steps is not cleaned up.
How to verify correct configuration
- Upload a single Excel test file containing 15,000 rows of data, confirm parsing completes without error prompts.
- Trigger a 3-level nested loop test node, review workflow logs to confirm no nested level limit exceeded errors.
- Run the full workflow, check that the generated daily report file only contains final summary content, with no reference markers from intermediate steps.
- Review scheduled task logs to confirm the workflow automatically triggers execution at 08:00 daily.
