Comparing DDMs

This document covers the following topics:

Prerequisites

See also General Prerequisites for Comparison Functions.

If Natural Security is installed and the file (DDM) has been defined to the Security system, only administrators may compare the file. Also, if the file object in Natural Security has an Owner list, the DDM may be compared only by one of its owners. No countersignatures are necessary.
