CMS_STR_MSG_COL_MESSAGE_OBJ 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 "Format for Return Code and its corresponding Message" 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_CMS_STR_MSG_COL_MESSAGE_OBJ TYPE CMS_STR_MSG_COL_MESSAGE_OBJ.
The CMS_STR_MSG_COL_MESSAGE_OBJ table consists of various fields, each holding specific information or linking keys about Format for Return Code and its corresponding Message data available in SAP.
