CIF_BLOCK 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 "Structure for Block Number of Filter Objects" 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_CIF_BLOCK TYPE CIF_BLOCK.
The CIF_BLOCK table consists of various fields, each holding specific information or linking keys about Structure for Block Number of Filter Objects data available in SAP. These include BLOCKNO (Block Number for Processing Delta Model)...
