MEFv2

The latest (default) version of the MATRIXX Event File (MEF), introduced in release 5100. MEFv2 reflects changes to the MATRIXX Digital Commerce system architecture. It contains a list of events (both usage and non-usage), however balance tracking information is now contained in events themselves instead of being listed separately within the MEF. MEFv2s contain events that are now organized by the global transaction counter (GTC) value. MEFv1 and MEFv2 are incompatible within the same MATRIXX Digital Commerce environment. You can control when MEFs are generated by specifying limits on time, number of events, or file size. In this documentation the generic term "MEF" refers to both MEFv1s and MEFv2s. Where there are differences the text refers to either "MEFv1" or "MEFv2" specifically.
