FCOMS_ORDER_ADDFIELD 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 "Program positions data and Depreciation simulation 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_FCOMS_ORDER_ADDFIELD TYPE FCOMS_ORDER_ADDFIELD.
The FCOMS_ORDER_ADDFIELD table consists of various fields, each holding specific information or linking keys about Program positions data and Depreciation simulation data data available in SAP.
