COMS_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 "Help Structure for Copying" 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_COMS_COPY TYPE COMS_COPY.
The COMS_COPY table consists of various fields, each holding specific information or linking keys about Help Structure for Copying data available in SAP. These include ATTRIBUTE_NAME_TO (Char 20), SETTYPE_NAME_FORM (Text field length 14), SETTYPE_NAME_TO (Text field length 14)...
