CMS_STR_LR_DE_DB 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 "Structure for Persistency Layer" 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_LR_DE_DB TYPE CMS_STR_LR_DE_DB.
The CMS_STR_LR_DE_DB table consists of various fields, each holding specific information or linking keys about Structure for Persistency Layer data available in SAP.
