GRRM_OB_S_API_SDM_DATA 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 "Static Data Management Parameters" 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_GRRM_OB_S_API_SDM_DATA TYPE GRRM_OB_S_API_SDM_DATA.
The GRRM_OB_S_API_SDM_DATA table consists of various fields, each holding specific information or linking keys about Static Data Management Parameters data available in SAP.
