1/15

All Exercises

Prerequisites

- Good understanding of XI features- Good understanding of BPM features

Overview

The business case for the complete process is a simplified selling of spare parts. The spare partsare selected in a non-SAP Catalog/CRM-System, which is in our exercises simulated by a WebDynpro user interface. Since the non-SAP Catalog/CRM System sends the spare part items inindividual messages, the process starts with a collect pattern (exercise Receive Order Items). Inthe Receive Order Items exercise the order items are merged into a single message which is then

used in the Preparations exercise where the preparations in the SD system are done. ThePreparations exercise consists of a synchronous call to the SD system to check whether missingmaterials have to be created. If so, the materials are created in the Create Materials exercise bylooping through a list of missing materials and sending each material to the receivers, which arefound using a receiver determination step (MM and SD system). In the Create Orders exercise, asales order and a purchase order are created. The last exercise - Send Purchase Order toSupplier- covers the communication with the supplier who receives and confirms the purchaseorder. Exception handling is also part of the exercises.

In order to focus on the modeling of the process we hide complexity. Therefore, we have simplemessage types and there are no mappings between process interfaces and the interfaces usedby the business systems. In fact, we simulate the business objects (e.g. create Material, createOrder) using ABAP proxies in the business systems, which are physically the clients 811(Supplier), 812 (SD), 813 (MM) in the Integration Server box. Moreover, the Integration Directory

configuration is preconfigured and so does not have to be done by the participants.

The following graphics show the business scenario, which is separated in five exercises:

1. Receive Order Items2. Preparations3. Create Materials4. Create Orders5. Send Purchase Order to Supplier

At runtime, the following business systems are used:

Exercise 1: Receive Order Items

The aim of the exercise is to collect three incoming order items. The incoming messages arrivefrom the SOAP adapter. This is triggered by a Web Dynpro application.

Part 1 Find your own business process and check theenvironment

1. Log on to the Integration Server: http://:/rep .The instructor will provide you with the names of the and the .

2. Navigate to your business process: software component

SELLSPAREPARTS Business Scenarios & Processes Business Processes

If you are in Group XY, your business process is SellSpareParts_0XY.(Process SellSpareParts_000 is reserved for the instructor and demo purposes)

SellSpareParts_0XY is the only repository object you are allowed to change.

Initially, your process template only contains one receive step. If you run into trouble during thecreation of the exercises, you can open the exercise solution in a second window for guidance.If you are not able to finish an exercise, you can delete your process and recopy it from thesolution template. Make sure that you use exactly the same process name as before. Forexample, if you want to start with exercise 3, you can start by resetting you process from theSolution_2 process. Make sure that you activate the process.

Part 2 Test the initial state of your business process

By executing this step you test the system environment.

1. Select the urlhttp://:/webdynpro/dispatcher/local/OrderSparePartItem/OrderSparePartItem

The server and port names are the same as above. They are provided by the instructor.

2. Enter the name of your business process in the Process Definition field.This is very important; otherwise you will send the data to a different process.

NOTE:

You might run into problems with endless running processes caused by the wrongprocess design. In this case, the workflow log shows an older protocol time stamp. Toavoid interference with these process instances use a different Customer Number.

3. Click SendItem .OrderItem has been submittedis displayed.

4. Log on to the Integration Server (ABAP stack, client 800) and check intransaction SXMB_MONI whether you can see your SparePartItem message.The Receiver Service column must display the name of your process .

You may use the/SPAREPARTS layout for the list layout:

5. Check the Workflow log (refer to the screenshots below):

6. Select your process instance by calling transaction sxmb_moni_bpe.Enter the name of your process in the Service field on the selection screen, thenchoose Execute.

Double-click the process instance to open the Workflow log:

Use the transaction SXMB_MONI_BPE to find your process instances.

Step 3 Building the collect pattern

1. Delete the receive step in your scenario.

2. Insert the following block:

3. Define a container element counter, (type xsd:integer):

4. Insert a loop with the condition counter 3:

5. Create a correlation CorrCustomer::

Make sure that in the XPath expression the Multiline check box (lower right corner) isdeselected. This is necessary for all XPath expressions you create in correlations or ifyou use/activate a correlation in a send or a receive step.


13/15

6. Define a container element item in the process container:

7. Define a receive step:

Make sure that in your XPath expression the Multiline check box is deselected (lowerright corner).

8. Define a container operation on the element counter:

9. Create a container multiline element itemlist:


14/15

10. Define a container operation to append a single item from container element item to thelist of items in container element itemlist:

Make sure that the Multiline check box is deselected.

11. Save and activate your process. Next, send three items to your process by using theWeb Dynpro user interface. (submit three times):


15/15

12. Check the workflow log of your process. It should look as follows:

As you send three items with the same customer number they are collected by theprocess. After the third item, the condition becomes TRUE; therefore the loop is finishedand the process is complete.
