Dunning notices not printed

Hello Gurus,

I've been trying to run transaction F150. before running this i manually cleared all the dunning data in the vendor master except for the dunning procedure, configured in FBMP.

I run this and get the following message.

>Minimum charges and dunning interest Phase III

>Generate dunning data Phase IV

Step 002 started (program SAPF150D2, variant &0000000000013, user ID MJOHNSON)

> Start print phase

0 dunning notices were read

0 dunning notices have been printed
