latest update -- only do dunning on invoices, not on storno or credit . I ( my software ) recently sent dunning to customer on credit I learned that the hard way. Dunning Level 1 fully automated , then 2,3 ( Inkasso ) manually inside dunning in Idempiere .
Our idea btw : Simplify that guy so a simple user is able to manage -- only 3 DunningRun MAX , called "Level 1","Level 2", "Level 3".
They have their entries, which are managed by user.
Here user 1) activates specific dunningrunentry, also unsets "processed", then klicks "Create dunning run" . thats it
