Last Dunning Data not generated for customer account

Hi Gurus,

I have run the Dunning for a customer, it was successfully data generated to the customer account and able to see dunning history until 1st and 2nd runs, but 3rd and final dunned but no data generated for the particular customer.

In this time i find few other line items are additioned to the previous line item.

The 3rd dunning days are already exceeded the grace days, but not data generated because of additional items are not eligible for dun this time they have good enough time as grace days.

So this is caused, and no data generated to the for the respective line item which has to get the data for it's 3rd dun.

When i run for some future time 3rd dunning was successfully got and data updated, for additional items also got dunned 1st reminder this time because they are also eligible this time..

In my dunning procedure i have selected for always dun for all intervals and print line items for last dun.

Your inputs are highly appreciated.

Thanks in advance, points are avails.

Thanks,

Vyas
