How to read attachment data in mapping

Question

Hi,
In my scenario I receive an XML file with another file as attachment. I need to map both the content of the XML file and the attachment to the target which will be sent as an attachment in a mail.
I have used JavaMapping and I'm now able to send the mail with the attachment. But i'm not sure how to  read the contents of the attachment in the mapping.
Any help would be appreciated.
Thanks,
Bhargav

Hello Bhargav,
It depends on the version of SAP PI you have,
Prior to Version 7.1 there was no support to access attachments in a Mapping Programm, so in that
case the only way to handle it is e.g. to access it in an adapter module (dependent on your scenario).
In SAP PI 7.1 you can easily access an attachment within a mapping.
Within a Java mapping program this can be done with the TransformationInput Class, calling the method getInputAttachments() which will give you all available attachments.
Also see the SAP PI 7.1 javadocs (com.sap.aii.mapping.api):
https://help.sap.com/javadocs/pi/SP3/xpi/index.html
In a graphical mapping you can access attachments within a UDF through the GlobalContainer parameter:
GlobalContainer globalContainer = container.getGlobalContainer();
InputAttachments inputAttachments = globalContainer.getInputAttachments();
With best regards
