Hi Vered,
There is an option of changing the dunning level of a particular dunning item through FPM3.
Give the date ID, identification and the contract account for which you want to make changes in the dunning level in FPM3.
On executing, select the line item for which you want to change the dunning level and select dunning line items (Shift+F4) from the Goto menu
A next screen will pop-up, which would display the dunning at the document level.
Select the document for which you want to reduce the dunning level and select next dunning level (Shift+F4) from the Goto menu.
A pop-up will come up and will ask for setting the new level and saving it.
so during the next proposal run, the item will get dunned at the new level.
Hope it helps.
Thanks,
Amlan
