Standalone SAP Queued IDoc Destination Endpoint Quick Start

Demonstrates the sap-qidoc-destination component running in a standalone camel runtime.
SAP Tool Suite

Author: William Collins - Fuse Team
Level: Beginner
Technologies: SAP, Camel, Spring
Summary: This quickstart demonstrates how to configure and use the sap-qidoc-destination component in a standalone Camel environment to send Intermediate Documents (IDocs) to SAP. This component sends documents to SAP using the Queued RFC (qRFC) protocol.
Target Product: Red Hat Build of Camel Spring Boot Source: http://github.com/jboss-fuse/sap-quickstarts/

What is it?

This quick start shows how to integrate Apache Camel with SAP using the JBoss Fuse SAP Queued IDoc Destination Camel component. This component and its endpoints should be used in cases where a camel route is required to send Intermediate documents (IDocs) to an SAP system and ensure that the documents are processed in the SAP system in the same order that they were sent.

This quick start contains a route with an initial timer endpoint which triggers and executes that route once. The route uses processor beans to build FLCUSTOMER_CREATEFROMDATA01 type IDoc documents to create Customer records in SAP. These documents are routed to sap-qidoc-destination endpoints which use the qRFC protocol to send these documents to the inbound queue QUICKSTARTQUEUE in SAP. When this queue is triggered, the documents are delivered in order to the ALE subsystem in SAP which creates the Customer records. The route logs to the console the serialized contents of the documents it sends.

In studying this quick start you will learn:

  • How to configure the Camel runtime environment in order to deploy the JBoss Fuse SAP Queued IDoc Destination Camel component.
  • How to define a Camel route containing the JBoss Fuse SAP Queued IDoc Destination Camel component using the Spring XML syntax.
  • How to use the JBoss Fuse SAP Queued IDoc Destination Camel component to send IDocs to SAP.
  • How to configure connections used by the component.

System requirements

Before building and running this quick start you will need:

  • Maven 3.6.2 or higher
  • JDK 11
  • Red Hat Build of Camel Spring Boot
  • SAP JCo3 and IDoc3 libraries (sapjco3.jar, sapidoc3.jar and JCo native library for your OS platform)
  • SAP instance with Flight Data Application setup.

Configuring the ALE Subsystem

To send IDocs from the quick start's route to your SAP system, you must first configure the Application Linking Enabling (ALE) subsystem in your SAP system:

  1. Using the SAP GUI, run transaction SALE, the ALE Implementation Guide.

  2. Ensure that Logical Systems for the quick start and your SAP client have been defined:
    a. Run the Define Logical System step (Basic Systems > Logical Systems > Define Logical System).
    b. Click New Entries and create and save the following logical systems:

     | Log.System | System     |   
 | ---------- | ---------- |     
 | QUICKSTART | QUICKSTART |      
 | QUICKCLNT  | QUICKCLNT  |

    c. Return to the SALE transaction main screen (Goto > Back).

  3. Ensure the QUICKCLNT logical system has been assigned to you SAP client:
    a. Run the Assign Logical System to Client step (Basic Settings > Logical Systems > Assign Logical System to Client).
    b. Select the QUICKCLNT for your client's Logical system and save your changes.
    c. Return to the SALE transaction main screen (Goto > Back).

  4. Ensure the destination QUICKSTART has been defined:
    a. Run the Create RFC Connections step (Communication > Create RFC Connections).
    b. Create a new destination (Edit > Create):
    1. RFC Destination : QUICKSTART.
    2. Connection Type : T.
    3. Technical Settings :
    i. Activation Type : Registered Server Program.
    ii.Program ID : QUICKSTART.
    4. Unicode:
    i. Communication Type with Target System : Unicode
    c. Return to the SALE transaction main screen (Goto > Back).

  5. Ensure that a Model View for the message flow from the quick start to your SAP system has been defined:
    a. Run the Maintain Distribution Model and Distribute Views step (Modelling and Implementing Business Processes > Maintain Distribution Model and Distribute Views).
    b. Ensure a QUICKSTART model view has been created with the technical name QUICKSTART (Edit > Model view > Create).
    c. Ensure the QUICKSTART model view has a BAPI call configured (Edit > Add BAPI):

    1. Sender/client : QUICKSTART.
    2. Reciever/server : QUICKCLNT.
    3. Obj.name/interface : FlightCustomer.
    4. Method : CreateFromData.
      d. Ensure Partner Profiles have been generated for the quick start and your SAP client (Environment > Generate Partner Profiles).

Configuring the Quickstart for your environment

To configure the quick start for your environment:

  1. Deploy the JCo3 library jar and native library (for your platform) and IDoc3 library jar to the lib folder of the project.
  2. Ensure that the SAP Instance Configuration Configuration Parameters in the parent pom.xml file (../../.pom.xml) of quick starts project has been set to match the connection configuration for your SAP instance.

Build and Run the Quickstart

To build and run the quick start:

  1. Change your working directory to the sap-qidoc-destination-standalone directory.
  • Run mvn clean install to build the quick start.
  • Run mvn camel:run to start the Camel runtime.
  • In the console observe the contents of the IDoc processed by the route.
  • Execute the queued IDocs waiting in the inbound queue QUICKSTARTQUEUE. Using the SAP GUI, run transaction SMQ2, the Inbound Queue qRFC Monitor:
    a. Select the QUICKSTARTQUEUE queue.
    b. Display the queue contents (Edit > Display Selection).
    c. Select the entry for your Client connection and activate the queue (Edit > Activate).
  • Using the SAP GUI, run transaction SE16, Data Browser, and display the contents of the table SCUSTOM.
  • Search the table (Edit > Find..) for the newly created Customer records: Fred Flintstone, Wilma Flintstone, Barney Rubble, and Betty Rubble.

Stopping the Quickstart

To stop the camel run-time:

  1. Enter Ctrl-c in the console.
