What the data for this category looks like
Intelligent due diligence reports for coatings and inks are primarily used by financial institutions for credit due diligence on coatings and ink manufacturers within their supply chains. Data is sourced from public industry association ledgers, safety production license documents from manufacturers, compliance test reports from third-party testing institutions, and quotation records from upstream raw material suppliers.
Update frequencies vary across data types: raw material price data is updated weekly, enterprise production capacity and compliance reports are updated quarterly, and batch quality inspection data is generated synchronously with production batches. Most documents are in PDF format. Core fields include raw material proportion ratios, VOC emission concentrations, production batch numbers, and compliance test grades. Common units are milligrams per cubic meter, kilograms, and percentage.
What constraints do these characteristics impose on workflow orchestration
The multi-source and varied update cadence of coatings and ink due diligence data requires workflows to be configured with differentiated trigger rules per data type. This avoids repeatedly pulling old data or missing the latest updates.
The mixed text and structured table format of PDF documents requires workflow nodes to prioritize calling the table parsing module. This ensures accurate extraction of core fields.
Differences in units across fields — such as milligrams per cubic meter for VOC concentrations and percentage for raw material proportions — require built-in standardized conversion rules in workflows to unify output formats.
Batch-level real-time quality inspection data requires workflows to support dynamic binding of production batch variables. This avoids conflicts between global variables and batch variables.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Coatings and ink due diligence documents often contain complex tables, and take longer to parse than general documents. 300 seconds covers parsing time for most long documents |
chunk_split_size | 800–1200 characters | Preserve complete row context for raw material proportion tables, to avoid splitting and breaking table fields |
GLOBAL_VAR_VALIDATE_LEVEL | Dynamic validation based on current context | Adapt to variable requirements across different workflows, and avoid conflicts from required variable validation across workflows |
API_ENABLE_GLOBAL_VAR | Enabled | Support passing dynamic variables such as production batch numbers and test dates via API, to adapt to batch-level due diligence requirements |
workflow_save_retry_count | 2 retries | Offset save failures caused by network fluctuations, and reduce the probability of configuration loss |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After switching from a workflow node configured with required global variables to a node without required variables, the system still triggers a "missing required global variables" error. Cause: The global variable validation context for the current session was not reset, and validation rules from old configurations were not cleared when switching across workflows.
- Phenomenon: Workflow configuration changes show as saved successfully, but the configuration reverts to its pre-modification state after refreshing the page. Cause: The page was closed before waiting for the save API to return a 200 status code, or network fluctuations caused the save request to not be fully submitted. This issue is relatively common in version V4.8.10.
- Phenomenon: Global variables passed via API calls to the workflow are not recognized, and the workflow output fields are empty. Cause: The
API_ENABLE_GLOBAL_VARconfiguration item was not enabled, or the passed variable name did not match the variable name defined within the workflow.
How to confirm the configuration is correct
- Upload a standard industry-compliant coatings and ink due diligence PDF document, trigger workflow execution, and verify that the parsed output fields cover the preset core due diligence content.
- Switch the global variable configuration associated with the workflow, verify that the system's required variable prompt matches the current configuration, and there is no redundant cross-configuration validation.
- Use an API call tool to pass test variables, confirm that the workflow can correctly read and apply the passed variable values.
- Wait for the workflow configuration save to complete, then refresh the page to verify that the configuration is retained, with no abnormal rollback.
