This setting is NOT available for Twinfield and Visma eAccounting
In addition to the creditor/debtor level, it is possible to set a default journal for purchase and sales invoices at the administration level.
Go to Settings (Cogwheel) and click on Administrations. Click on the Pencil behind the relevant administration and click on Settings tab.
Here you can set the default journal for purchase invoices (purchase journal) and for sales invoices (sales journal)
The standard journal is always used, unless the debtor/creditor indicates on which journal the invoices must be posted. In that case, the setting at the creditor/debtor level will be used.
