EAMS_VB_S_NODE_ACTION_DATA 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, the data retreived by an action for the node" 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_EAMS_VB_S_NODE_ACTION_DATA TYPE EAMS_VB_S_NODE_ACTION_DATA.
The EAMS_VB_S_NODE_ACTION_DATA table consists of various fields, each holding specific information or linking keys about Structure, the data retreived by an action for the node data available in SAP. These include NODE_NAME (Node Name), ACTION_NAME (ID of the FPM Event), NODE_DATA_REF (), NODE_DATA_STRUC (Name of Dictionary Type)...
