This feature is currently only available for MYOB Ledgers. We'll let you know when it's available for Essentials Accounting and AccountRight Live ledgers.
When you add a new journal in workpapers, we'll automatically display it in the asset register. It'll show up as New in the Name column.
Click the asset ellipsis next to a new item and select Allocate or Ignore. If you select Ignore, we'll remove it from the asset register, but you'll still see it in your ledger.
