Assigning Dunning proc to CA and Document Items : Configuration question.

Hi There,

How is a dunning procedure assigned to Contract Account or Documents.

There appear to be three places where we can assign dunning procedures

1) When we define and parametrize external transactions.

2) On the Contract Account Object

3) On the document Item Object

If the dunning procedure is assigned to Contract Account level, the Contract Account will be dunned.

If the dunning procedure is assigned to the document at item level, the item is dunned.

How are these two assigned (other than manually opening each CA or Item and assigning them individually)?

1) How do we configure so that Dunning can take place at Contract Account level?

and

2) How do we configure so that Dunning can take place at Document item level?

Thank You.
