SIQM_SX_SOURCE_NODE 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 "IQM source object node" 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_SIQM_SX_SOURCE_NODE TYPE SIQM_SX_SOURCE_NODE.
The SIQM_SX_SOURCE_NODE table consists of various fields, each holding specific information or linking keys about IQM source object node data available in SAP.
