MSAM_MO_TOB_HEADER 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 "Header Data for Technical Object" 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_MSAM_MO_TOB_HEADER TYPE MSAM_MO_TOB_HEADER.
The MSAM_MO_TOB_HEADER table consists of various fields, each holding specific information or linking keys about Header Data for Technical Object data available in SAP. These include TPLNR (Functional Location), FUNCLOC_DISP (Functional Location Label), BEGRU (Technical object authorization group), EQTYP (Equipment category)...
