Thanks to all of you guys, actually this a requirement for a client of my company a project that will be starting next month, there for I have not got all the information to which extend are they planing to use PD, as far as I know that they are implementing only the PA and PD models!! so there will be no PY or OM or Time and for sure no ESS MSS, from your comments I can note that it is possible to implement PD without OM, it only question of functionality where they will not be getting all the functionality of PD?? can any one guide through the the way of doing that???
FOr example in the case of PA OM need to switch of the integration for IT0001, what is the case for PD?
kind regards, and thanks again for your time and advice
