Feedback, bug reports (especially messages that should validate but fail, or vice versa) and feature requests are welcome:

Email: [email protected]

When reporting a validation problem, please include:

• which tool you used (VDA 4987 / VDA 4984),
• what the tool reported vs. what you expected,
• if possible, an anonymised sample message (replace real company codes, part numbers and quantities - the structure is what matters).

We read everything and usually answer within a few working days.
