Functionality
This function module CACS00_BUILD_ISCD_DOCUMENT_CPD calls the functionmodule CACS00_BUILD_ISCD_DOCUMENT for converting meta document to thestructure of ISCD. It is checked in advance, whether CpD data -alternative payees - are present in the settlement items. If there areseveral alternative payees for each document, a new document number mustbe used, because the later called function module for transferring thedata in ISCD can process only one payment recipient per document. Therecently created document number is marked in the table CACS_CPD_REF.This table is accessed while reversing a document.
