COMS_ATTRIBUTE_INT_EXT_MAPPING 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 "Mapping of External to Internal Attribute" 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_COMS_ATTRIBUTE_INT_EXT_MAPPING TYPE COMS_ATTRIBUTE_INT_EXT_MAPPING.
The COMS_ATTRIBUTE_INT_EXT_MAPPING table consists of various fields, each holding specific information or linking keys about Mapping of External to Internal Attribute data available in SAP.
