IAOM_OBJECT_ATTRIBUTE 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 "Attribute of a Controlling Object - see Documentation" 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_IAOM_OBJECT_ATTRIBUTE TYPE IAOM_OBJECT_ATTRIBUTE.
The IAOM_OBJECT_ATTRIBUTE table consists of various fields, each holding specific information or linking keys about Attribute of a Controlling Object - see Documentation data available in SAP. These include VALUE (Characteristic Value), FIELD_NAME_OREXT (Component Name for Master Data Internal Order Component), FLDNAME_RECEIVER (Component Name for Component for Specified Account Assignmnt), STRUC_NAME_COPA (Table Name)... 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. .
