ICS_ITEMSV 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 "Attributes of ICLITEMSV" 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_ICS_ITEMSV TYPE ICS_ITEMSV.
The ICS_ITEMSV table consists of various fields, each holding specific information or linking keys about Attributes of ICLITEMSV data available in SAP. These include CURR (Currency of Actual Cash Value), REFNO (Reference number)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
