CMS_STR_GEN_GUID 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 "General Guids for checks" 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_GEN_GUID TYPE CMS_STR_GEN_GUID.
The CMS_STR_GEN_GUID table consists of various fields, each holding specific information or linking keys about General Guids for checks data available in SAP.
