User Defined Message Search in SAP CPI
INTRODUCTION
User-Defined Message Search allows one to search a message based on the content in the incoming payload. This feature is not available in SAP CPI as a standard configuration. However, it can be achieved by using the two header parameters mentioned below.
Table Of Content
- SAP_ApplicationID : This header parameter is assigned a Key value from incoming message using Xpath condition/expression.
- SAP_MessageType : This header parameter is used to give a description about SAP_ApplicationID or to specify from which element the value is being taken. This usually is a constant.
HYPOTHETICAL SCENARIO
The source is triggering ‘n’ messages where each message is differentiated by Order Number field in the payload as below
Message 1 :
<Order_MT>
<orderNumber>1</orderNumber>
<supplierName>Walt1</supplierName>
<productName>Timber1</productName>
</Order_MT>Message 2:
<Order_MT>
<orderNumber>2</orderNumber>
<supplierName>Walt2</supplierName>
<productName>Timber2</productName>
</Order_MT>And so on…
Say you want to Find a message with Order Number = 5 in monitoring out of processed thousands of messages,
In this case,
- SAP_ApplicationID : //orderNumber
- SAP_MessageType : Order Number
Sample Integration Flow would look as below:
EXECUTION STEPS
Step 1: Create an Integration Flow with HTTPS connection.
Step 2: Use a Content Modifier to add SAP headers as stated above.
Step 3: In In Message Body, use ${in.body} to add an incoming message.
Step 4: Save and Deploy the flow.
Step 5: Copy the endpoint from Overview Window once the Deployed flow is started.
Step 6 : Trigger some 10 messages from POSTMAN by changing the <orderNumber> value.
Step 7: Check that all your messages are successful in Overview Window.
Step 8: Now, In order to search a message with Order Number =5, you just have to type 5 in the ID search bar and hit enter as shown below. All the messages with Order Number = 5 in the incoming payload will be Displayed.
This simple Custom step makes searching a message a lot easier.
A practical Example could include searching a message using Document Number in IDOC to any scenario.
