This error message means that an asset has been created without the mandatory Intacct dimensions. In this case 'Department'. When an asset does not have the required dimensions for your Intacct setup, Intacct won't accept the journal lines.
This can be fixed by ensuring all assets have a value for the 'Department' dimension;
- Then delete the current journal,
- Re-run the journal,
- And post the new journal to Intacct.
