CMS_RE_STR_EXT_TYP 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 "External type 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_CMS_RE_STR_EXT_TYP TYPE CMS_RE_STR_EXT_TYP.
The CMS_RE_STR_EXT_TYP table consists of various fields, each holding specific information or linking keys about External type data data available in SAP.
