Converted items were updated with dunning lock effective 04/01/2012 until 12/31/9999. Dunning ran on 04/02/2012 with issue date of 04/02/2012. These converted items were not excluded even though the documents have dunning lock at the document level. What would be the reason why this happened?
Please check the below thing.
In FPL9 open the particular dunning item, go to the "Dunn Data" tab, there is a field called "DunnLockReason", next to this field there is "Right Direction" arrow, click the same, and check the validity date, check the other details.
