ESH_WS_SEARCH_RELATION_DEFINIT 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 "Information for start and end point of a relation" 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_ESH_WS_SEARCH_RELATION_DEFINIT TYPE ESH_WS_SEARCH_RELATION_DEFINIT.
The ESH_WS_SEARCH_RELATION_DEFINIT table consists of various fields, each holding specific information or linking keys about Information for start and end point of a relation data available in SAP. These include TEMPLATE_ID (Identifier for a Search Template), NODE_ID1 (Identifier for the Search Node), MINIMUM_CARDINALITY_VALUE (Minimum Cardinality for Relations of Enterprise Search), MAXIMUM_CARDINALITY_VALUE (Maximum Cardinality for Relations of Enterprise Search)...
