Approval type user workflow (NAV2016)

Good morning,

I set up on the condition approval type workflow usergroup.
I also set up the edit approval user set up .

I wonder if I is there a place a I need to give the name or the code of the workflow user group a create ?



You can create workflow User Group in “Workflow User Groups”.
Departments/Administration/Application Setup/Workflow/Workflow User Groups

IN a workflow user group you can have multiple users and sequence in which they will receive approval request.

My question how can I link my workflow purchase journal batch to a my usergroup workflow.
My workflow purchase journal batch is enabled.
I already set up on the condition approval type : usergroup workflow.
But I dont see how to link it .
Could you tell my what I m missing or what I should do?
