Receive CSV attachment via Mail Adapter and process into ABAP proxy

Hi,
I have the following scenario:
1. Receive e-mail with CSV attachment
2. Process through Mail adapter (KeepAttachments = Yes in order to retain the CSV attachment)
3. Receive into ABAP proxy (with CSV attachment)
The next step is to read the attachment in the ABAP proxy and process the CSV attachment data into CRM.
The CSV attachment contains the data I wish to process - the body of the e-mail will not contain this information.
The problem I have is reading the attachment data in the proxy - not sure of the methods/class to call - anyone got any ideas ?
Another question is this the best way to do this and process the CSV attachment data ?
I know I could use the PayloadSwapBean to switch the payload to the attachment but then I am stumped with how the attachment is processed through PI 7.1 - how do you transform the CSV format payload into XML so PI will be able to process it through mapping.
Either option is viable - an answer to either question would be great.
1. How do you read the attachment data in an inbound ABAP proxy ?
2. How do you transform the CSV attachment data after the PayloadSwapBean from CSV to XML ?
Kind regards
Colin.

Hi Colin
As you are not interested in processing the body of email. Swap the payload to the attachment using the PayloadSwapBean
Change the content from CSV to XML using MessageTransformBean. Now pass this information to Proxy. You dont need to deal with attachments in proxy.
It is not possible to read attachment in server proxy because the class and interface you create will not have data type which can refer to an attachment processing interface in ABAP.
Thanks

File attachement in mail adapter

Hi ,
I need to send users an error report which I have captured in the form of a file. Is it possible to attach this file as an attachement via mail adapter. I have been reading that the payload can be sent as attachment by specifying the interface namespace and interface name. But my requirement is to trigger the mail once the file has been completely written and not for every message. The reason being I could have 3000 records in the file and I dont want to send 3000 MAILS out but just 1 mail for the entire 3000 records...
Thanks,
Teresa

Hi Teresa,
I hope, I understand you right.
When you use the file-adapter for sending the file, you can without mapping send this file out to a mail receiver as attachment, there is nothing special to do.

Hi
have a look at this
You can use Java/ABAP proxies to do this job for you..
Java Proxy >> will read the mail(with the attachments) with the help of Java APIs and send the message into XI ABAP Proxy >> for this you will have to first convert the attachment into a message and then you can proceed in the regular fashion.
Not all adapters can process attachments, I'm not sure why you are having trouble with using module processor in the mail adapter. Just check if the service pack that you are using supports this feature.
If you are on WAS 6.10 and above you can achieve this and there is an excellent weblog by Thomas Jung on this topic at
/people/thomas.jung3/blog/2004/09/09/receiving-e-mail-and-processing-it-with-abap--version-610-and-higher

This is regarding CBMA in SAP PI 7.3.1. I have set up the alert mail using default java mail client.I do receive the alerts via mail. But my requirement is to direct all the mails to Business workplace inbox in ECC.

This is regarding CBMA in single stack SAP PI 7.3.1. I have set up the alert mail using default java mail client.I do receive the alerts via mail. But my requirement is to direct all the alert mails to Business workplace inbox in ECC.
So I need to set up PI to redirect mails to ECC Business workplace user inbox (sbwp). From here rules are set up & routed per distribution list.
Please guide me how I can achieve this requirement.

Hi,
yes, it is a little bit different. This is the issue.....
But I am not sure if your links will help:
1) /people/william.li/blog/2008/02/13/sap-pi-71-mapping-enhancements-series-using-graphical-variable
is about a different solution. I do not need to count the number of lines of the source message.
And the second variable is about concat line by line from unbound node to unbound node.
My issue is:
Souce:
Message line (0...unbound) ! ! ! ! ! ! ! !
.    ResultLine   (1..1)
Mapping:
=>   ResultLine1
       ResultLine2
       ResultLine........          => into UDF to an element (1..1) in one mapping operation.
So that all "ResultLine"s are included.
The result is explained in the given link for Mail attachment with UDF.
So I am not sure how to use this thread for my issue.
In the comments of that blog Christoph Gerber writes that the new variable feature can only handle single values.
So it is not suitable for my purposes as I have a list of values here that needs to be moved into the target message field.
2) http://wiki.sdn.sap.com/wiki/display/Java/UsingEditJavaSectioninMessageMapping
shows where to find the button "Java section" which is not available here in 7.1
3) /people/sap.user72/blog/2005/10/01/xi-new-features-in-sp14
too is about the nice little button for Java Section that is no longer existing on PI 7.1 screen for mappings.
So my issue is: How to replace the Java section function with global variables in PI 7.1?

Cannot receive/send emails via Mail on Mac using 10.6.8, keeps asking for password, very frustrating. Any ideas please? Regards

One more time, iCloud mail accounts are .me, .mac and .icloud. New ones are only .icloud.
iCloud mail is a standard Imap account that can be used with any mail client in existence. But You are talking about the ability to automatically setup an iCloud account in mail, which did not exist until 10.7.2.
You can use password or token authentification with iCloud mail (in Mail) it is your choice.
Set the account manually, set it as Imap, use imap.mail.me.com (no P number) for the incoming email and smtp.mail.me.com as the outgoing server.
The full settings (ports and security) are here. Use them and it will work, regardless of domain (mac, me and icloud addresses all use the same settings.
IMAP (Incoming Mail Server) information:
Server name: imap.mail.me.com
SSL Required: Yes
Port: 993
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
SMTP (outgoing mail server) information:
Server name: smtp.mail.me.com
SSL Required: Yes
Port: 587
SMTP Authentication Required: Yes
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
Note: If you receive errors using SSL, try using TLS instead. SSL is required for both IMAP and SMTP connection with iCloud. POP is not supported by iCloud.
For more information on how to use this information with your email application, consult your application's documentation.

How do get an image on a Samsung HD TV via HDMI adapter and cable?
Currently get a static image of the desktop and then a grainy gray picture.

If it's like mine, I used another post's advice. Go to system preferences, then display and click on "mirror". Then in system preferences go to sound and click on "HDMI". I did this while I was connected to my Samsung TV and it worked then.

Wanted to put a file via a drag and drop into applications on my finder sidebar. it missed and landed in the sidebar itself. i can not remove it. i can not even highlight it. how can i remove it from the sidebar.

I wanted to put a file via a drag and drop into applications on my finder sidebar. it missed and landed in the sidebar itself. i can not remove it. i can not even highlight it. how can i remove it from the sidebar.

Try holding down the Command key and dragging the file well off the sidebar.
Hope this helps.

Dynamic attachment name with receiver mail adapter and use mail package

We need to send mapped XML payload as attachment (with dynamic name) to a recepient (recepient email id is part of input xml payload, but not part of the mapped XML payload).
I could probably do this using the adapter module (as per the following link),
http://wiki.sdn.sap.com/wiki/display/XI/Adapter%20Module%20PI%207.0%20Set%20Attachment%20Name?bc=true
I would like to explore if this would be feasible using Mail package and XI payload.I already have a Java mapping that is converting the input XML to required Output format. If I am using Mail package (XI Payload), how do I go about sending this Output XML from java mapping as attachment to email id available in the input payload?

Hi,
1) XML payload as attachment (with dynamic name)
2) recipient (recipient email id is part of input xml payload, but not part of the mapped XML payload)
These two is possible by using Mail Package. You have a standard xsd for mail package which you can download from the SAP Note 748024.
The xml created in you java mapping which will be your attachment should be put into the <content> tag of the mail package xml structure. and the file name can be set in the <Content_Type> tag.
<?xml version="1.0"; encoding="UTF-8"?>
<p2:Mail xmlns:p2="http://sap.com/xi/XI/Mail/30">
<Subject>My Invoice</Subject>
<From>from email address<;/From>
<To>to email address</To>
<Content_Type>text/plain;name="MyFile.csv";</Content_Type> --> file name here
<Content>123;A49;aaa</Content> -> attachment xml here
</p2:Mail>
And you have to select MailPackage in the receiver mail adapter.

Plain text and attachment in Mail Adapter (Receiver)

Hello,
we have to generate a mail in the mail-adapter with a specific text and an attachment.
The attachment is a document in pdf-format, that is generated inside an adapter-module out of the payload-document.
An additional text has to be added to the mail for the receiver in plain-text-format, like "Dear customer ... enclosed you will find ...".
Is it possible to mix plain-text and attachments in the mail adapter? Does anybody know how we can do that?
Regards,
Thorsten

Hi,
yes you can do it very easily inside the adapter module
if you're already using the adapter module then
you can just enhance it a little bit
you can add the pdf to the attachment section and
leave dear customer in the standard payload
you can even make it a little bit more dynamic
and create a module that will take the input from
the communication channel config (modules tab) - for example xml tag name in which you will specify
the dear customer (or any other text) and after this
the pdf creating can use the xml without this tag...

Receive mail with PDF attachment into XI and send to ABAP proxy

Hi,
I have a scenario where I need to receive a mail into XI that has a PDF attachment. This attachment needs to be retained as ultimately I need to send the message into CRM via an ABAP proxy and read the attachment and load against a business partner.
However, as I am only on SP13 I do not have the parameters such "Keep Attachments" available to use.
So I have two questions:
1. How do I receive the mail into XI with the PDF attachment ?
2. How do I read the attachment in an ABAP proxy ?
Any guidance in either question would be appreciated.
Cheers
Colin.

hi,
you say that there's no keep attachment
indicator but does the XI store the attachment or not?
maybe it stores all attachmens
(I work with sp16 and I don't remember how it worked with sp13)
but try maybe it accepts attachments by default
then it would be quite easy
if you use then use the attachement in abap proxy
(like I said you won't have to use any java)

Sender Mail Adapter Configuration - Process Multiple Attachments

Dear sirs,
I need to process several attachments at the same mail message as individual payloads.
In default configuration of sender mail adapter only the body of message is used as payload.
So I added PayloadSwapBean Module at Processing Sequence and it processed the attachment I set in Module Configuration. I'm not able to process all attachments available, just one attachment is sent to PI pipeline.
How can I process all attachments of a single mail message?
Thank you in advance.

From message to attachment in Mail adapter

Hello,
I am searching for information about this issue:
An incoming message from a WebService needs to be mapped to a target structure . SAP PI has to create a file (csv) and add it as an attachment to a mail.
So this is the process:
WebService -> Mapping -> File -> Attachment in eMail
I am not sure if this is possible to move the target structure as a csv-file attachment into the eMail.
Please can anybody help!
This is really appreciated!
Best Regards
Dirk

Thank you, Hareenkumar!
The first link seems to be the right one to help me!
So the solution should be to use a Java mapping to generate the required file structure
and add it then as an attachment to the mail.
And thank you, Abhishek!
I will try this first as it seems to be easier to implement for me.
But this needs some weeks as we are analyzing requirements currenly and need to find out what is possible with PI and what is the effort for impolementation!
So I will come back later!
Regards
Dirk
