SIMP_PARAMETERS_1 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 "IMP: Parameters as Key Values Pair" 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_SIMP_PARAMETERS_1 TYPE SIMP_PARAMETERS_1.
The SIMP_PARAMETERS_1 table consists of various fields, each holding specific information or linking keys about IMP: Parameters as Key Values Pair data available in SAP. These include PARAM_NAME (IMP: Parameter Name (Free Format)), PARAM_VALUE (IMP: Parameter Value (Free Format))...
