RDEFCAP_ADMIN 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 "Administration Data for Payment Agreements" 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_RDEFCAP_ADMIN TYPE RDEFCAP_ADMIN.
The RDEFCAP_ADMIN table consists of various fields, each holding specific information or linking keys about Administration Data for Payment Agreements data available in SAP. These include IDUNNBLCK (Dunning Block for Items for Deferral or Capitalization), IIOABLCK (Interest on Arrears Block for Items for Deferral/Capitaliz.), IDUBLDEFI (Dunning Block for Deferral Installments), IIOABLDEFI (Interest on Arrears Block for Deferral Installments)...
