Transaction /PACG/ECM_TRIG_PRERV serves the purpose of sending person reservations from SAP to the cloud. The only obligatory field is Company ID.
Usually there’s no need to use it since data entered in PA30 as Absences are sent automatically with idocs of type /PACG/ECM_ITYPE_PERSRESERV.
The reservation can be found on the Planning and Dispatching board as a grey and striped field.
The sending report is called /PACG/ECM_TRIG_PERSRESERV. It transfers relevant reservations from the PA2001 table, based on the selection criteria. It can be noticed that all the entries of this table contain a personnel number.
New idocs of type /PACG/ECM_ITYPE_PERSRESERV are generated only if a person reservation is sent with the deletion flag and then resent again. If a reservation already exists, logs inform that no new objects were created.
