UPS_YS_EVENTLONG is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Structure of Database for Event Coupling" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_UPS_YS_EVENTLONG TYPE UPS_YS_EVENTLONG.
The UPS_YS_EVENTLONG table consists of various fields, each holding specific information or linking keys about Structure of Database for Event Coupling data available in SAP. These include TEILPLAN (Subplan in STS), VERSION (Planning Session/Version), ORGVL (Org. Value for Status and Tracking System), FROMEVENT (Status in Status and Tracking System)...
