SAP Note 16546 - Dunning letter - printing interest

Symptom:

Although the interest record MHND-ZINSS is filled in the print data, no interest is printed in the layout set.

Cause and prerequisites

Whether interest is printed or not depends on the dunning level.

Solution
In the MHND print data, field XZINS is decisive for printing the interest. If this field is set to "X", the interest amount is set to zero.
You should check the settings for each dunning level (with or without interest) for the selected dunning procedure. If no interest was defined for a dunning level, MHND-XZINS is always set to "X" by the dunning program whenever this dunning level is selected.
