BAPIACCAHD 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 "Add. Contract Accounts Recievable and Payable Header Line" 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_BAPIACCAHD TYPE BAPIACCAHD.
The BAPIACCAHD table consists of various fields, each holding specific information or linking keys about Add. Contract Accounts Recievable and Payable Header Line data available in SAP. These include DOC_TYPE_CA (FI-CA: Doc.Type for Contract Accounts Receivable and Payable), RES_KEY (FI-CA: Reservation Key), FIKEY (FI-CA: Reconciliation Key for General Ledger Accounting), PAYMENT_FORM_REF (FI-CA: Payment Form Reference)... 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. .
