Use
If you do not want to send the dunning notices to the customer or vendor that owes the receivable in question, you can send the dunning notice to an alternative recipient.
Prerequisites
Ensure that you have created a master record for the business partner to be dunned and for the alternative dunning recipient. Enter the account number of the alternative dunning recipient in the field
Dunning recipient under Correspondence in the company code-specific area of the customer or vendor to be dunned.
