Process Integration (PI) & SOA Middleware:Creating File Name from Mail Attachmentusing Standard Beans

Posted by sivasakthi danasekaran Apr 2, 2013Business Driver Purchase and Sales information is sent from a partner via Email as a CSV attachment. PI hasto poll the Email server, retrieve these mails and write the CSV files in PI server directory with exactly the samename as the mail attachment. Solution This requirement has popped up many times in the sdnforumsand the solution to this currently is to deploy a custom adapter modulehttp://wiki.sdn.sap.com/wiki/display/XI/Adapter+Module+PI+7.0+Get+Attachment+Name But the same requirementcan be sufficed with absolutely no coding or creation of adapter modules. This can be achievedwith 3 standard beans: MultipartHeaderBean ,PayloadSwapBean and DynamicConfigurationBeanIn this blog I have highlighted only the specific settings that have to be maintained in thecommunication channels to achieve our requirement, all the other ESR & ID objects should becreated as usual. Sender Email Channel Settings In the sender email communication channel makesure to check the Keep Attachments option , which is required to retain the attachment.Also check the Set Adapter-Specific Message Attributes option to enable the DynamicConfiguration attributes to be available.

The MultipartHeaderBean enables us to access the attributes of other payloads that areappended to the XI message asan additional attachment. In the Module tab add the MultipartHeaderBean with the followingparameters:Parameter Name Parameter Value

requiredHeaders All

dcNamespace http://sap.com/xi/XI/System/Mail

Using the PayloadSwapBean here we can replace the application payload of the XI messagei.e. email content, with another payload that is appended to the XI message i.e. the attachmentAdd the PayloadSwapBean with the following parameters:

Parameter Name Parameter Value

swap.keyName Payload-Name

swap.keyValue MailAttachment-1

Receiver File Channel Settings

Now in the Receiver File adapter we are going to use the DynamicConfigurationBean to retrieve the

attachment name.

The attachment file name is available in the Dynamic configuration attribute Part[1].Content-Description, which

we will write to the PI message interface name.

To the 'Module' tab add the DynamicConfigurationBean with the following parameters:

Parameter Name Parameter Value

key.0 write http://sap.com/xi/XI/System/Mail

Part[1].Content-Description

value.0 message.interface

Using Variable Substitution, create a variable fname referencing the message interface name and access this

variable in the file name field.

Testing

The configurations are complete. Its time to test our scenario.A sample mail is sent to the mail account which the sender email adapter is polling with the attachment name

MyAttachment1.CSV

Pic 3.1

Integrated configuration was used in this scenario, so we can see the Dynamic Configuration message

attributes in message monitoring.

Note that Part[1].Content-Description has been set to MyAttachment1.CSV at runtime.

The payload was swapped successfully and the attachment data has been set to the main payload as shown

below.

Hi Sivasakthi,

Is it possible to pick the .PDF files from Emails and place them on FTP server with the same file name?

thanks-

Ramesh

Hi Sivasakthi,

Your blog helpmed me a lot in creating the same with SOAP attachments.

Everything worked fine, except the file name generation. In dynamic configuration the file name is coming as

. As '' are not permitted in creation of file name, PI is generating it with underscores

(_filename.ext_).

I rectified this issue by using an UDF. But just want to know is there any other way to get the correct file name

in adapter level.

Nice blog siva

One clarification:

If it is FTP folder instead of NFS any specific change need to do or only the adapter selection is enough.
