If you’re using debt collection you might want to apply a processing fee against the borrowers. First add the charge code for this fee, and then apply the charge to the borrower categories. Then select this charge code as a processing fee when you set up the debt collection parameters.
For example, you might specify "DCN" as the code for the charge, and "Debt collection fee" as the description. Set Allow manual removal/setting to Yes, and leave all the other parameters as null or No.
Rather than apply the charge to specific borrower categories, you might want to apply it to the default category and then inherit all the charges from the default.
