RFC Function Module

Connector Type RFC Function Module is used to call Function Modules on remote SAP Backend systems. It follows principle of passing Function Module input in a XML representation package into common Connector envelope:

XML

<FunctionModuleCall name="BAPI_PO_GETDETAIL1" rfcdest="ED1">
	<InputPayload>
		<IMPORTING>
			<PURCHASEORDER>4500024151</PURCHASEORDER>
		</IMPORTING>
		<TABLES>
			<RETURN/>
			<POITEM/>
		</TABLES>
		<EXPORTING>
			<EXPHEADER/>
		</EXPORTING>
	</InputPayload>
</FunctionModuleCall>

Key values to be passed in the call:

@name - name of the Function Module to be called
@rfcdest - RFC Destination pointing to the system when Function Module must be executed - passed from Business Object template in field DESTINATION
InputPayload - under this node full Function Module input needs to be specified.

To specify TABLES that should be populated as a result of Function Module execution transformation needs to initialize them using <TABLENAME/> there is no need of providing more detail information.

Result of RFC Function Module Connector execution are return in format as below:

XML

<FunctionModuleCall name="BAPI_PO_GETDETAIL1" rfcdest="ED1">
	<Result>
		<IMPORTING>
			<PURCHASEORDER>4500024151</PURCHASEORDER>
		</IMPORTING>
		<TABLES>
			<RETURN>
              <BAPIRET2>
                <TYPE>S</TYPE>
                <ID>06</ID>
                <NUMBER>017</NUMBER>
                <MESSAGE>Standard PO created under the number 4500024328</MESSAGE>
                <LOG_NO/>
                <LOG_MSG_NO>000000</LOG_MSG_NO>
                <MESSAGE_V1>Standard PO</MESSAGE_V1>
                <MESSAGE_V2>4500024328</MESSAGE_V2>
                <MESSAGE_V3/>
                <MESSAGE_V4/>
                <PARAMETER>POHEADER</PARAMETER>
                <ROW>1</ROW>
                <FIELD/>
                <SYSTEM>T90CLNT090</SYSTEM>
              </BAPIRET2>
            </RETURN>
		</TABLES>
		<EXPORTING>
			<EXPHEADER>
              <PO_NUMBER>4500024328</PO_NUMBER>
            </EXPHEADER>
		</EXPORTING>
	</Result>
</FunctionModuleCall>

RFC Function Module Connector specific parameters:

Parameter Counter	Parameter Function
1	Function Module name - check against XML input @name to verify if correct Function Module is being called
2	Commit work flag - if set to “X”, commit work will happen after Function Module execution
