ESH_S_ADM_LOGSYS 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 "Logical system and RFC destination" 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_LOGSYS TYPE ESH_S_ADM_LOGSYS.
The ESH_S_ADM_LOGSYS table consists of various fields, each holding specific information or linking keys about Logical system and RFC destination data available in SAP. These include RFCDEST (Logical Destination (Specified in Function Call))...
