Return value of R/3 systme information field.

nIndex: index into a list of R/3 system information fields.

A CRfcData object containing the value of the field whose index is given as argument. This CRfcData object’s content can be integer or character string, and should be extracted using one of its unary cast operators.

None.

The system information is stored in a list and each list element can be accessed by index. The list contains all the fields in the structure export parameter RFCSI_EXPORT of RFC_SYSTEM_INFO and the simple export parameters of RFC_SYSTEM_INFO. This function should be used in conjection with CRfcConnection::R3SystemInfoCount() for iterating through the entire list.
