SPKO1 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 "Communication table (Partner and address management)" 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_SPKO1 TYPE SPKO1.
The SPKO1 table consists of various fields, each holding specific information or linking keys about Communication table (Partner and address management) data available in SAP. These include TABNAME (Table Name), KEY1 (First key field), ADRNR (Address number), ADRTYP (Type of partner address)... 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. .
