Hello experts,
I am trying to do the customization on SAP ME 15.1 and NWDI had been installed and configured.
However, when I was trying to extend a class ApplicationInterface and it was in SAPMELEGACY SC in SAP ME 6.1. I checked the Official Developer Guide and the LEGACY is not a must one.
I am wondering whether it is OK to go without LEGACY and where I can find the classes from LEGACY.
