Exit of Contract Accounts from Dunning Procedure

Hello,

I need to identify the moment when a contract account comes out of the dunning procedure.

In other words, when the open items of a contract account are paid, the dunning run does not processes it anymore, but no trace of the exit from the procedure remains directly in the system.

Is there a way to locate the exact date in which a contract account comes out of the dunning procedures?

Thanks and regards,

Ermanno
