ESH_S_ADM_PARAM 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 "Configuration Parameter" 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_ADM_PARAM TYPE ESH_S_ADM_PARAM.
The ESH_S_ADM_PARAM table consists of various fields, each holding specific information or linking keys about Configuration Parameter data available in SAP. These include VALUE (Config Parameter Value), TIMESTMP (UTC Time Stamp in Short Form (YYYYMMDDhhmmss)), LOGSYS (Logical system)... 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. .
