BAPI_EHAUADR 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 "CRM: Address Connection Object" 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_BAPI_EHAUADR TYPE BAPI_EHAUADR.
The BAPI_EHAUADR table consists of various fields, each holding specific information or linking keys about CRM: Address Connection Object data available in SAP. These include TPLNR (Functional Location), BUILDING (Building (Number or Code)), STREET1 (Street), STREET2 (Street)... 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. .
