PROTOCOL_COPY 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 "Log for Copying Rules Eligible for Cover" 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_PROTOCOL_COPY TYPE PROTOCOL_COPY.
The PROTOCOL_COPY table consists of various fields, each holding specific information or linking keys about Log for Copying Rules Eligible for Cover data available in SAP.
