CMS_STR_NOTES_MODIFY_KEY 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 "Key fields required for create/change note (non-dialog)" 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_NOTES_MODIFY_KEY TYPE CMS_STR_NOTES_MODIFY_KEY.
The CMS_STR_NOTES_MODIFY_KEY table consists of various fields, each holding specific information or linking keys about Key fields required for create/change note (non-dialog) data available in SAP. These include TEXTOBJECT (Text Object for the Business Entities in CMS), NOTES_GUID (Key for Identifying the Note)...
