## Summary - **Root cause**: The UBL schema template used string `"0"` placeholders for numeric fields, causing the MLLM to return locale-formatted strings (e.g. Swedish `"2,34"`) instead of JSON numbers. AL's `AsDecimal()` then stripped the comma, turning `"2,34"` into `234`. - **Fix 1** (`ubl_example.json`): Changed all numeric string `"0"` placeholders to `0` (JSON numbers), teaching the model to return proper numeric values. - **Fix 2** (`EDocMLLMExtraction-SystemPrompt.md`): Added explicit rule requiring XML decimal format (period as decimal separator, no thousands separators). - **Fix 3** (`EDocMLLMSchemaHelper.Codeunit.al`): Replaced `AsDecimal()` with `Evaluate(…, AsText(), 9)` in `GetDecimal()`, which parses XML-format decimals locale-independently — consistent with how `GetDate()` already handles date strings.
