TYP_CMP_IDX 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 "TYP_CMP_IDX" 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_TYP_CMP_IDX TYPE TYP_CMP_IDX.
The TYP_CMP_IDX table consists of various fields, each holding specific information or linking keys about TYP_CMP_IDX data available in SAP.
