Problem Mail-Adapter attachment with specified name

Question

Hi,
We have the following scenario:
We have some EDIFACT-suppliers which we have to connect over Mail-adapter.
We have to fullfill several specifications by sending the mail.
So we have to create a specific filename for the EDI-attachment and the subject. Therefore I used the adapterspecific attribute THeaderSUBJECT, which we set in Mapping. This works fine.
Now the problem: We have to send only the payload-document as attachment of the mail with the same name as the subject of the mail. So we can't use the keep-attachment flag because then all attachments of this message would be sent in the mail.
How is it possible to send only the payload as attachment without any other documents and with specified filename in the attribute THeaderSUBJECT?
Has anybody an idea how to solve this problem?
Regards

Hi,
I have found a solution.
In a new module I copy the original paload to the payload of a new message object without attachments.
After calling this module I call the standard module MessageTransformBean to transform the payload into the attachment of the message.
Here the code of my module:
String fileName = msg.getMessageProperty("http://sap.com/xi/XI/System/Mail","THeaderSUBJECT");
// Generate new message object
Context ctx = new InitialContext();
ConnectionFactory cf = (ConnectionFactory) ctx.lookup(com.sap.aii.af.ra.ms.api.ConnectionFactory.JNDI_NAME);
MessageFactory factory = cf.createMessageFactory("XI");
Message msgnew = factory.createMessage(msg.getFromParty(),msg.getToParty(),msg.getFromService(),msg.getToService(), msg.getAction());
msgnew.setConversationId(msg.getConversationId());
msgnew.setDeliverySemantics(msg.getDeliverySemantics());
msgnew.setCorrelationId(msg.getMessageId());
msgnew.setMessageProperty("http://sap.com/xi/XI/System/Mail","THeaderSUBJECT",fileName);
String contentType = new String("text/plain;name="" + fileName + """);               
// Copy original message to the new message
XMLPayload payload = (XMLPayload)(msg.getDocument());
payload.setContentType(contentType);
payload.setDescription("file");
payload.setName(fileName);
msgnew.setDocument(payload);
Now it works like it should work.
