ABAP Proxy with attachment --------> Mail (Content + File Attachment)

[Former Member]

Hi,

I have scenario from ABAP Proxy with attachment to Mail. The problem is i cannot send mail both mail content and file attachment.

Because when i tick the "keep attachment" in the mail adapter so both content and attachment become attachment, but if i didn't tick, only mail content is display by the recipient without the attachment.

How can i configure mail adapter so the recipient can receive both mail content and attachment.

Thank you and best regards

Hi William,

Yes, i have resolved the problem already, The workaround is to using module in mail adapter. You can see my code, but you need to modify little bit for your case. Don't tick "keep attachment" in the mail adapter cc.

Let me know if you still have a problem, so far my program running well without problem.

Suddhasatta,

The ex Cape Town man?

No Suddha your solution did not work. Still getting two attachments and no body.

Any other ideas?

[former_member192375]

Hi Fernand ,

Did you ever got this question of yours resolved? If yes please can you expain to me how you did it. I want to achieve exactly the same.

Hi Willie,

Please follow the following steps if you want to send a mail from XI mail adapter with a body and attachments.

For this, your XI message need to have additional attachements to it, which should be sent by the Sender system. Each of these additional XI payloads (XI attachments) will then become an attachment for the mail.

To set these additional XI payloads as attachments,

Check the Keep Attachments check box in the Receiver Mail Adapter Channel.

Now, the main payload of the XI message is by default sent as an attachment of the mail, whether you check the Keep Attachments option or not. To send the main XI attachment as the body of the mail do the following:

1. Go to the "Modules" tab of the receiver mail channel.

2. In the processing sequence area of this tab specify the localejbs/AF_Modules/MessageTransformBean as the first module. Type: Local Enterprise Bean; Module Key: <any_name>

Then in the Module Configuration area enter the following module parameters,

Module Key: <any_name>

Parameter Name: Transform.ContentDisposition

Parameter Value: inline

Module Key: <any_name>

Parameter Name: Transform.ContentDescription

Parameter Value: <any_description>

Module Key: <any_name>

Parameter Name: Transform.ContentType

Parameter Value: text/plain

Be careful while entering the module names and values, do not put any spaces at the end.

Hope this helps.

Suddhasatta

Hi,

I already using MessageTransformBean as the first module and set its module parameter "Transform.ContentDisposition" as "inline" but then both payload still become attachment.

i want to make the MainDocument = body and the attachment still remain as attachment.

Please advise.

Hi,

In Mail adapter u need give

Message protocol as "XIALL"

Regards,

Hi Fernand,

The mail adapter sends the XI payload as an attachment by default. Checking the option "Keep Attachment", sends additional attachment to the XI message as Mail Attachments. For each

additional payload of the XI message, the mail adapter creates an attachment for the

mail; when you select "Keep Attachment".

Although by default, the main payload of the message is also sent as an attachment, if you want to send the payload as Content (Body) of the mail............in module configuration use MessageTransformBean as the first module and set its module parameter "Transform.ContentDisposition" as "inline" (to keep it as attachment you can set the value as "attachment" as well).

You can also use Mail package in message mapping to set the message content in the mapping.

Hope this helps.

Regards,

Suddha

Ur message protocol option is correct. Check this for various options.
