調用函數BAPI_BILLINGDOC_CANCEL1

搞了半天都是cx_sy_dyn_call_illegal_type錯誤。

??CALL?FUNCTION?'BAPI_BILLINGDOC_CANCEL1'
????????EXPORTING
??????????BILLINGDOCUMENT?=?IT_ITEM-VBELN
*?????????TESTRUN?????????=?''
*?????????NO_COMMIT???????=
??????????BILLINGDATE?????=?IT_ITEM-FKDAT
????????TABLES
??????????RETURN??????????=?LT_BAPIRETURN1
??????????SUCCESS?????????=?LT_BAPIVBRKSUCCESS.

到后來才發現是return和success的參數顛倒了，居然沒有報錯，哎
