BAPI_RCOMHRTC 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 "PP-PI-PMA: Return Code for New Messages (Header Data)" 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_BAPI_RCOMHRTC TYPE BAPI_RCOMHRTC.
The BAPI_RCOMHRTC table consists of various fields, each holding specific information or linking keys about PP-PI-PMA: Return Code for New Messages (Header Data) data available in SAP.
