Posted: Tue Apr 01, 2008 5:18 pm Post subject: SAP RFC SDK and C++

В первую очередь хотелось бы узнать кто писал и каких успех добился. Хочу вызвать ФМ средствами C++. ФМ получает информацию из спула и передает в экспортируемую таблицу. на PHP модуль отрабатывает, а средствами C++ удается только запустить ФМ, но не получить выходные данные)))если кто поможет, буду только рад. Хотелось бы увидеть любые исходники и даже кусочки строк.

Примеры и исходники на С идут вместе SAP GUI в архиве RFC.SAR Для распаковки запустите sapcar -xvf [путь к sapgiu]\SDK\NT\I386\RFC.SAR Про C++ почитайте документ RFC C++ Class Library (BC-FES-AIT)

That's okay. Here is an example for retrieving the company code list using BAPI

Запускает ФМ Z_ASM_MON_PERCH(Exporting JOB_NAME, JOB_STEP Import I_BUFF) Входные 2 строковых параметра, на выходе значение взятое из спула фонового задания ZZ_INPUT_DOC_2_STEP2.

Видимые спорные моменты. Почему у экспортных параметров указывается itab?
exporting[0].addr = ltab;

Видимо вы должны создать переменную нужного типа, заполнить ее значением и передать через параметр addr указатель на эту переменную. Например так:

Code:

RFC_STRING input0;
input = RfcAllocString (32);
strcpy ((char *) input0, "ZZ_INPUT_DOC_2_STEP2");
exporting[0].name = "JOB_NAME";
exporting[0].nlen = strlen ((char *) exporting[0].name);
exporting[0].type = RFCTYPE_STRING;
exporting[0].addr = &input0;
exporting[0].leng = strlen((char *)input0);

RFC_STRING input1;
input1 = RfcAllocString (10);
strcpy ((char *) input1, "6");
exporting[1].name = "JOB_STEP";
exporting[1].nlen = strlen ((char *) exporting[1].name);
exporting[1].type = RFCTYPE_STRING;
exporting[1].addr = &input1;
exporting[1].leng = strlen((char *)input1);

С табличными параметрами тоже нужно поаккуратней

Code:

ltab = ItCreate( "I_BUFF", 100, 0, 0 );

tables[0].name = "I_BUFF";
tables[0].nlen = 6;
tables[0].type = RFCTYPE_CHAR;
tables[0].leng = 100;
tables[0].itmode = RFC_ITMODE_BYREFERENCE;
tables[0].ithandle = ltab;
