[SAP CPI] – SCENARIO FOR RFC RECEIVER ADAPTER WITH CLOUD CONNECTOR

Hi guys, in this article I want to discuss about scenario How to send message XML from third party system to SAP backend with RFC adapter receiver, SAP Cloud Connector and SAP CPI. This scenario use for in cases integration with SAP backend system by RFC connection. For clearly, kindly take a look this diagram

A. SAP Cloud Connection Configuration

Step 1 : Add mapping virtual to internal system

• Click Cloud to On-Premise
• Click Add

Step 2 : Add resource for this mapping. Choose function name on SAP backend

• Choose Virtual Host
• Click Add Resource (below)
• Enter function name (Function module or Webservice Define on SAP)
• If have many Function Name, we can add many times

If in integration flow, we check option Send Confirm Transaction, we have to add 2 following function name :

– BAPI_TRANSACTION_COMMIT

– BAPI_TRANSACTION_ROLLBACK

Everything will look as after done

B. SAP CPI Configuration

Step 1 : Add new destination

• Go to SAP BTP
• Click Destinations on left side menu. Under Connectivity
• Click button New Destination

• (1) : Name. This Name will use as connection name in RFC receiver adapter of integration flow

• (2) : Type : RFC
• (3) : OnPremise
• (4)(5) : User / Pass of SAP ERP. This user must be take ROLE accordingly

Step 2 : Add property of destination

Now, we have to add some property of destination which create in step 1. Add following property

jco.client.ashost	Virtual host on SCC
jco.client.client	Client of SAP ERP. EX : 190
jco.client.lang	Language. Ex : EN
jco.client.sysnr	System number of SAP ERP. EX : 00

Step 3 : CPI integration flow design

C. Issues

Issue 1 : If body send request invalid structure XML of Function Module, we ‘ll receive this message.

When take this issue, we have to check structure XML of Function Module and fix it.

D. Test case

For test purpose, we use standard function module : SXIDEMO_AIRL_FLIGHT_CHECKAVAIL

Structure XML of this function module as

<?xml version="1.0" encoding="UTF-8"?>
<ns0:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL
	xmlns:ns0="urn:sap-com:document:sap:rfc:functions">
	<FLIGHT_KEY>
		<AIRLINEID/>
		<CONNECTID/>
		<FLIGHTDATE/>
	</FLIGHT_KEY>
</ns0:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL>

Case 1 : No resource of this function module in SAP Cloud Connector

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL.Exception
	xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
	<Name>Partner signaled an error for conversation ID [69507688] : Access denied for SXIDEMO_AIRL_FLIGHT_CHECKAVAIL on sap-ecd-app:sapgw00. Expose the function module in your Cloud Connector in case it was a valid request.</Name>
	<Text>Partner signaled an error for conversation ID [69507688] : Access denied for SXIDEMO_AIRL_FLIGHT_CHECKAVAIL on sap-ecd-app:sapgw00. Expose the function module in your Cloud Connector in case it was a valid request.</Text>
	<Message>
		<ID/>
		<Number/>
	</Message>
	<Attributes></Attributes>
</rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL.Exception>

Case 2 : Invalid date

com.sap.it.rt.adapter.http.api.exception.HttpResponseException: An internal server error occured: 
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL.Exception

	<Attributes>
		<V1> 0000 20220202</V1>
	</Attributes>
</rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL.Exception>.

Case 3 : Invalid structure xml in Body request

com.sap.it.rt.adapter.http.api.exception.HttpResponseException: An internal server error occured: <?xml version="1.0" encoding="UTF-8" standalone="no"?><rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAILs.Exception xmlns:rfc="urn:sap-com:document:sap:rfc:functions"><Exceptions>

</Exceptions></rfc:SXIDEMO_AIRL_FLIGHT_CHECKAVAILs.Exception>.
The MPL ID for the failed message is : AGI7Xs4vl3zVENgi_6XYmcdoSr6E

Case 4 : OK

<?xml version="1.0" encoding="UTF-8"?>

	xmlns:ns0="urn:sap-com:document:sap:rfc:functions">

		<FLIGHTDATE>20021221</FLIGHTDATE>
	</FLIGHT_KEY>
</ns0:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL>
