RSISW_S_M_DATAOBJ_GET 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 "Model: Data Object Name and Attribute" 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_RSISW_S_M_DATAOBJ_GET TYPE RSISW_S_M_DATAOBJ_GET.
The RSISW_S_M_DATAOBJ_GET table consists of various fields, each holding specific information or linking keys about Model: Data Object Name and Attribute data available in SAP. These include TXTSH (Short description), TXTLG (Long description), IOMODE (Data Object: I/O Mode (Imp, Exp, Changing)), CALLTYPE (Data Object Call Type)... 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. .
