Interactive KNIME Workflow Blueprints
Click any node to see its detailed configuration in a side panel. Each workflow includes a toggleable SQL alternative for use in DB Query Reader nodes. Designed for KNIME LTS 5.8.2 with KNIME Business Hub (Standard Edition).
1. VAT Return Data Extraction
Extract and aggregate all tax data for a specific entity and period. Uses DB nodes for server-side processing — only the small aggregated result is loaded into KNIME.
2. E-Invoice Status Dashboard
Monitor e-invoice submission success/failure rates by country. Includes error analysis branch for troubleshooting. Two outputs: dashboard matrix and error detail.
3. Reverse Charge Transaction Monitor
Pull all reverse charge (self-assessed) transactions from ZX_LINES, enrich with supplier details, and summarize by entity and jurisdiction.
4. Intercompany CIT Flow Analysis
Extract GL journal entries involving intercompany accounts, aggregate by entity pair, and produce a transfer pricing matrix.
5. Tax Data Quality Monitor
Flag anomalies in tax data: missing rates, negative tax on non-reverse-charge lines, zero tax on non-exempt items, rates above maximum known threshold.
