Dunning Locks 

Definition

Processing lock that causes items due for dunning to be restricted or not dunned by the dunning programs.

Use

You can lock individual items or entire contract accounts for dunning by specifying the relevant dunning lock reasons at the required level. You can also restrict the validity of a dunning lock to a specific period. If you set a dunning lock for a line item, only that item is excluded from the dunning run. A dunning lock at the business partner-contract account relationship level means that all items posted to this contract account are not dunned until the lock has expired or has been removed. If an item has a deferral date, it is not dunned until the deferral date has been exceeded.

You define dunning locks in the Customizing activity Define Dunning Lock Reasons. If you designate a dunning lock as dunnable and assign it to an item:

·        The item itself does not trigger a dunning notice; it can, however, be dunned with other items

·        The item is included in the dunning balance, but is not used for the amount limit check

·        The item does not change its dunning level
This means that it remains at dunning level zero, or retains a higher dunning level and does not contribute to the dunning level of the dunning notice

SAP recommends using this type of dunning lock for interest and charges. If you set such a dunning lock in the contract account, this has no effects. See also the documentation for the indicator.

 Items or contract accounts that have an incoming payment method but no incoming payment lock are excluded from the dunning run. In this case, the system assumes that the item or contract account concerned is to be paid via the payment run.
If the contract account of a business partner has a payment lock, and the payment method is only in the item and not in the account, neither the payment program nor the dunning program take account of the item.

In the industry component Insurance, you can set dunning locks at insurance object level. The rules and restrictions described above apply to these dunning locks.
