overlap on the automatic generate header/footer.

Accounting-related modules were updated to match a newer way of loading company chart of accounts data. This keeps enterprise features and Belgian payroll demo data aligned with the underlying accounting changes, reducing setup and test inconsistencies.

The manufacturing work order module now uses the updated planned date field name in the manufacturing order view. This keeps the screen aligned with related system changes and helps avoid confusion or display issues for users planning production.

Rename production field in inherited view.
