There are no further explanations for dunning activities here.
Technically, explanations are entries in the dunning activities tableFKKMAKT. Whether an entry is created depends on the function module withwhich the dunning activity is defined in Customizing.
Further explanations are only given for specific dunning activities,such as deactivating an installment plan.
The explanations are only available after you have executed the dunningactivity run as an update run.
