Over Due Charges in AR

We are looking at the setup for Over Due Charges in AR module and according to the delivered functionality, it appears that when setting up for ODC, we need to set them up based on the entry type. For a given business unit we do both Commerical and Gov clients and we did set them up both to have entry type as IN. So, when this invoice/ item goes to AR would I be able to determine the difference between these two invoices and can ODC be applied against only Commercial? Any documentation is much appreaciated. Thanks!
