How to configure multi dunning procedure to dun the consumers separate percentage if fails to pay

[engr_faizan1073_5]

Need advice from ISU FI-CA functional consultants. We have currently single dunning level where we charged consumers straight 10% of electricity charges if fails to pay within the pre-configured days (for example 14 factory calendar days for regular consumers). Now we have requirement that we need to charge 5% of electricity charges as late payment surcharge if consumer paid after due date within 3 days and after 3 more days (i.e. 17 days), charge 5% of electricity charges (total 10% of initial posted electricity charges).

How can we cater this requirement from Payment terms (or terms of payment), or dunning procedure, or dunning level.

hi engr_faizan1073_5, have you had a look at SPRO Business Transactions → Dunning → Dunning by Dunning Procedure → Configure Dunning Procedure? The dunning procedure is the driver for dunning.
You can define different dunning levels for each dunning procedure to determine the dunning frequency, and the calculation and posting of charges and interests. You can define minimum amounts and dunning activities for each dunning level. You can define minimum interest due for each dunning level so that it is posted. You can allocate a dunning procedure to contract accounts or for each individual line item. Your scenario almost falls into an 'interest' type scenario where x amount is charged at y interval. You will need to look at what you have configured and what may be appropriate to configure under either charges or interest. 

The dunning levels and appropriate dunning activities are determined based on the dunning groupings and items for dunning. The dunning activity run can result in a charge or interest posting, or updates in the dunning history and dunning activity history.
