POSTING_INTERFACE_DOCUMENT解决特别总账'W'类型的过账问题

Error F5246 "Special G/L transactions of type & are not supported" is being raised when trying to post a
document via BAPI (i.e. BAPI_ACC_DOCUMENT_POST).
环境
SAP Release Independent •
ERP Financial Accounting •
General Ledger Accounting •
Posting/Clearing •
Accounting interface •
重现问题
Enter a BAPI (i.e. BAPI_ACC_DOCUMENT_POST). 1.
Inform special G/L indicators class = 'W' (bill of exchange). 2.
Post the document. 3.
The system issues message F5246. 4.
原因
Bill of exchange postings are not supported by accounting interface, therefore a bill of exchange posting via
BAPI_ACC_DOCUMENT_POST is not possible. The reason for error F5246 to be raised is that the interface
posting with special G/L indicator W is not designed for a posting with this indicator for downpayment or bill of
exchange.
解决方案
In this case the bill of exchange documents should be posted manually in financial accounting.
Another option to post bill of exchange documents in an automated process is to use batch-input.

SAP给出的解决方案是采用BDC的方式，其实SAP有提供一个函数实现F-02的BATCH-INPUT，代码如下：
