PARTY_POSTAL_CODE 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 "City/Street postal code, with update indicator" 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_PARTY_POSTAL_CODE TYPE PARTY_POSTAL_CODE.
The PARTY_POSTAL_CODE table consists of various fields, each holding specific information or linking keys about City/Street postal code, with update indicator data available in SAP. These include UPDATE_INDICATOR (Indicator whether an element carries an updated value or not), VALUE (City/Street Postal Code)... 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. .
