MSAM_MO_USER_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 "User data" 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_USER_DATA TYPE MSAM_MO_USER_DATA.
The MSAM_MO_USER_DATA table consists of various fields, each holding specific information or linking keys about User data data available in SAP. These include PROFILE_ORDER (Order Profile), ORDER_TYPE_PROFILE (Order Type Profile), PROFILE_CONFIRM (Confirmation Profile), PROFILE_NOTIF (Notification Profile)...
