ESH_S_SEARCH_INPUT 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 "Search Input" 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_S_SEARCH_INPUT TYPE ESH_S_SEARCH_INPUT.
The ESH_S_SEARCH_INPUT table consists of various fields, each holding specific information or linking keys about Search Input data available in SAP. These include CONNECTOR_REQUEST_ID (Connector Request ID), CONNECTOR_REQUEST_ENABLE (Connector Request ID is enabled), CONNECTOR_REQUEST_ID_INVISIBLE (Connector Request ID for subrequest and related request)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
