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).
ℹ️ About the #Table# pattern — KNIME 5.x vs legacy DB nodes
If you have experience with older KNIME versions, you may be familiar with SQL that includes a SELECT * FROM #Table# AS table placeholder, sometimes followed by ALTER TABLE table ADD XYZ DECIMAL(10,2) and UPDATE table SET XYZ = ... lines. This pattern belongs to the legacy KNIME DB nodes (pre-KNIME 4.3) and is not used in the workflows on this page.
Legacy DB nodes (pre-KNIME 4.3):
- • Used
#Table#as an in-database temp-table placeholder - • Added computed columns with
ALTER TABLEstatements - • Computed values with
UPDATE table SET col = expr - • Required special connector support for DDL operations
KNIME 5.x new DB framework (used here):
- • The DB node chain (Table Selector → Row Filter → GroupBy → Reader) generates a single, clean SQL query
- • No
#Table#placeholder or DDL operations are needed - • Column computations are done in-memory after the DB Reader loads data into KNIME, using Math Formula or Column Expressions nodes
- • The SQL Preview tab in DB Reader shows the final generated query — always check it before running
Bottom line: If you see SQL with #Table# in a KNIME workflow, it was built on the legacy node set and should be migrated to the KNIME 5.x DB framework before deploying to KNIME Business Hub LTS 5.8.2.
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.
KNIME Business Hub Configuration
Scheduling on Business Hub
