MCLIKPB 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 "Reference Structure from MCLIKP for Function Module" 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_MCLIKPB TYPE MCLIKPB.
The MCLIKPB table consists of various fields, each holding specific information or linking keys about Reference Structure from MCLIKP for Function Module data available in SAP. These include SUPKZ (Statistics update indicator (post in/post out)), MANDT (Client), VBELN (Delivery), ERNAM (Name of Person who Created the Object)...
