Technical design options for File to File scenario

Dear all,
I need some inputs on the below requirement.
SAP BW system has to send some reporting data to one of the end systems.
1. What are the ways of interfacing between SAP BW and SAP XI. (I mean RFC, IDOC or File based mechanism)
2. The proposed way was File mechanism, BW producing a file and XI picking it up and sending it to the target system.
3. The file size of 1GB, can XI handle such huge amount of data. What is the maximum file size which XI can handle.
4. We need to archive the data after it has been transmitted to the receiver.
1) Do we have any standard way of archiving in XI.How long will the messages be stored in XI.
2) For any extra archival period, do we need to any configuration.
Please provide your inputs in finalizing this design.
Regards,
Younus

Hi,
>1. What are the ways of interfacing between SAP BW and SAP XI. (I mean RFC, IDOC or File based >mechanism)
You can Try Proxy to send the message from BW to PI
>2. The proposed way was File mechanism, BW producing a file and XI picking it up and sending it to >the target system.
    Is the Desicison made to go ahead with File
>3. The file size of 1GB, can XI handle such huge amount of data. What is the maximum file size which >XI can handle.
    The file size depends upon the Hardware ofthe system, If you Chunk and send the message that will be cool
> 4. We need to archive the data after it has been transmitted to the receiver.
As per your Requirement, As a default the messages processed in PI will be stored for 30 days.
> 1) Do we have any standard way of archiving in XI.How long will the messages be stored in XI.
    As a default the messages processed in PI will be stored for 30 days. You can Configure for more days
>2) For any extra archival period, do we need to any configuration.
    Yes, Default is 30 days.

HOW TO DELETE FILES or FOLDERS or Assets from Adobe Creative Cloud Brouser/Web Portal By: Kai Buskirk rev:130626
Adobe now burried deleting or trashing unwanted iteams files or folders in the Archive section of your creative cloud brouser/web portal.
Note!! - No longeer is there a standard TrashCan icon or simple Delete button... its burried in the archive sector: but why i ask?
An archive is an accumulation of historical records, or the physical place they are located.[1] Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative or social activities.
In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost always unique, unlike books or magazines for which many identical copies exist. This means that archives (the places) are quite distinct from libraries with regard to their functions and organization, although archival collections can often be found within library buildings
A person who works in archives is called an archivist. The study and practice of organizing, preserving, and providing access to information and materials in archives is called archival science. The physical place of storage is sometimes referred to as an archive repository.
To delete files folders or individual assests in the current incarnation of adobe creative cloud brouser/web portal rev:130626
1 - Check mark the box on left and select files or folders you would like Deleted/Trashed and move them to the ARCHIVE folder location inside your adobe creative cloud brouser/web portal....Then navigate to the ARCHIVE SECTION
2 - Once the files or folders you have check marked are moved to the ARCHIVE folder location you can select them for Permanant Deletion (Trash)
ps: you can also restore them......if you so choose....
3 - in case you missed this step after selecting/checking the files or folders in the ARCHIVE folder there is a small Triangle Selector drop down that will reviel the Permanently Delete option.... clicking that is the point of no return i think..... so do not be misled my the use of the term ARCHIVE.... DELETING PERMANANTLY IS DELETING YO!
4 - OK DONE NOW YOU GOT IT .....
Good Luck Happy House Cleaning.....
Wamest Blessings,

FTPS or SFTP for file scenario. Suggstions

Hi,
I have searched blog in sdn but do not get good blogs/links.
For File scenario which to use FTPS or SFTP.
How to do the configuration in XI and Visual admin.
Full points will be awarded.

Hi,
1) SFTP (Secure File Transfer Protocol)
"SSH File Transfer Protocol" or SFTP is a network protocol that provides file transfer and manipulation functionality over any reliable data stream. It is typically used with the SSH-2 protocol to provide secure file transfer. SFTP encrypts the session, preventing the casual detection of username, password or anything that is being transmitted. One key benefit to SFTP is its ability to handle multiple secure file transfers over a single encrypted pipe. By using a single encrypted pipe, there are fewer holes in the corporate firewall.
SFTP:
As per the latest SAP PI/XI support pack, it does not support SFTP via File Adapter.
So alternative approach to cater this requirement from XI is to make use of Unix Script at OS level to transfer the files from/to third-party systems.
Inbound Interface - i.e. third-party system ->XI->SAP:
File is transferred to a folder in SAP XI landscape from the third-party legacy system using UNIX Script with secured protocol. Once the file is ready in the XI landscape, File Adapter will poll this directory and file is picked up by NFS protocol.
Outbound Interface i.e. SAP->XI->third-party system:
XI is responsible for writing a file into a folder in the XI landscape. These files are transferred to the third-party system by executing UNIX scripts with secured protocol i.e. via sFTP.
Pre-Requisites:
Public key should be exchanged between external systems and the PI system.
UNIX shell script has to be developed and scheduled.
Advantages:
Highly Secured.
Ability to handle multiple secure file transfers over a single encrypted pipe .By using a single encrypted pipe, there are fewer holes in the corporate firewall.
Disadvantages:
Two-Step process i.e. XI>Temporary folder>External System and vice-versa
Files have to be temporarily stored in XI server.
Multiple failure points i.e. XI and Unix script execution
Maintenance of an external UNIX script.
Difficulty in monitoring the execution of the shell script as it cannot be monitored thru XI.
Need to generate keys and install it in the SFTP site as a pre-requisite i.e. SFTP clients must install keys on the server.
SFTP uses keys rather than certificates. This means that it can't take advantage of the "chains of trust" paradigm facilitated through Certificate Authorities.
Files from the XI server should be deleted/archived in a periodic manner to increase the disc space so that it will increase the performance.
Note: UNIX shell Script can be executed as a background job or' can be triggered from SAP XI through OS command at File adapter level.

          if(confirm == JOptionPane.NO_OPTION)
               return;
          elseWhy do you have a return statement in a void method? there's no need for this you can cut out the no part and just keep the yes

Webservice for File Scenario

HI Everyone,
Can i develop a webservice using .net platform for a file to file scenario using XI. How do i proceed.
I know how to configure file to file scenario using XI, but how shd i replicate the same scenario as webservice.
Any valueable inputs would be appreciated.
Regards,
Varun.

Hi,
I hope the below blog's scenario is similar to your requirement.
and here the RFC should be replaced by the Webservice for your requirement.

Sequence Number By Date Option For File Naming

I would like to see Lightroom have the option to have the sequence numbers be reset when the date changes and increment accordingly. For example, I have the file naming set to use Date (YYYYMMDD) Sequence Number (0001) and the sequence number starting at 1. As Lightroom is now I will end up with 200909010001, 200909010002, 200909020003, 200909020004, 200909030005 200909030006 etc. and what I would like to see is the option for 200909010001, 200909010002, 200909020001, 200909020002, 200909030001 200909030002.
This would make it much faster for renaming or import when using this combination of date and sequence in file names.

Hi
For the Transport Protocol "File Transfer Protocol (FTP)" files are always processed in ascending alphabetical order
If you want the file to be processed in sequence then you can use Quality of Service EOIO in the sender adapter.
The files are processed in the sequence they are picked up.
otherwise use BPM for File Sequencing..
Refer the following Threads

Design Approach for 1:N Multimapping scenario with SAP ECC Receiver

Hi Experts,
I am trying to find the best approach to implement the following scenario. its desribed as follows:
Legacy Database ->XI -> SAP scenario.
1. Pick records from database table with status ='n'
2. The records picked can have one or more RefNos i.e. if 2000 records are picked 1500 can have RefNo :1111 and rest 500 RefNo: 2222
3. 1st condition is to split the records into multiple messages if reference nos are different, so for scenario in point 2 it will be 2 messages. Secondly if the no of records are more than 1000 then split further into 2 message. So 1500 Ref No would be split into messages with 1000 and 500 records. Hence we get 3 messages. I know something similar was achieved in this blog:
</people/claus.wallacher/blog/2006/06/29/message-splitting-using-the-graphical-mapping-tool
4. Once the data is forwarded to ECC and its successfully updated, we need to update the status of the database table on the sender side to 'y';
So the point where i am not very clear as of now is,
1. What alternative I choose for PI-> ECC call? Its a 1:N multimapping split scenario and as far as I know the call has to go via AE, so is RFC the only option or is there a way to have a call with Proxy/IDOC? Or will there be an option to limit such a scenario at the JDBC Adapter level so that split is not needed. I am not sure if that can be achieved and is a better solution.
2. If I go for either of the approaches mentioned above, what is the best way to achieve point 4, i.e. update the database table at the sender. As JDBC Adapter would be async and hence we either use a Aysnc-Sync bridge(for proxy/rfc receiver) or some other option like triggering a outbound interface from SAP side with the update data?
Hope that experts can provide the inputs on the best way forward.Let me know if anything is missing from scenario details perspective.
Best Regards,
Pratik

Use the solution # 2, make it like this:-
DB (async) -> PI -> Proxy (sync) -> PI -> DB (async)
Just out of curiosity, why you breaking the records into 1000's in PI? Why not you select only 1000 records when polling the DB? That will help in improving the overall performance.

Mapping error for file scenario.

Hi ,
I am working with the help of this scenario to pick only selected files.
/people/mickael.huchet/blog/2006/09/18/xipi-how-to-exclude-files-in-a-sender-file-adapter
I am getting error in mapping . Everything i have checked its correct . Mapping is correct . but still its giving error . how can i solve it .
Error : RuntimeException in Message-Mapping transformatio~
Thanks ,
Syed.

Dear Syed Kumar
Based on the blog you are executing the scenario I guess. The scenario is clearly focusing on the picking up the files using the mask attribute in File Access Parameters.
As you mentioned clearly, that you are getting mapping error plz concentrate on how to rectify the mapping errors.
will guide to do so.
1. Go to SXMB_MONI and in the integration server and check for the message you are trying send.( I hope you did this)
2. As it is giving you mapping error, Double click onthe message Flag showing red.
3.Plz check the Payload XML content copy that content and paste in the message mapping Test section of IR.
4. Execute the Test. If you get the message at the receiver side there shouldn't be any error.
If you still get the error let me know.
Best of Luck
Reward Points If found use ful.

Do the Interface mapping test as well if you are successful in message mapping.

Options for File Share

I have a px12 device, and i am looking into migrating data over to this device. the question i have is what is the best way to access the new location to turn this into my file server.
our px12 device is going to be in a central hosted location, and we access files from a Terminal Server, through VPNs, and through Remote Web Workplace.
I have setup an iSCSI the perfomance is great, but it is tied to one server, and that is not what i am looking for. We can do the standard Network share, but the speed on transfers is not the best.
Is there any options between netwrok share and iSCSI that gives good performance on speed?

NFS has the same speed as ISCSI and can connect from the different location you menitioned. NFS is cumbersome when it comes to connecting to Windows. We would not be able to walk you through setting up NFS but if your IT department is familar with it, most likely would work better than ISCSI.

Best option for file storage

I want to archive some of my CAD files and other files on a 'by year' basis. Is a flash drive a good option? They seem neat but then again they are a bit small & could get lost. Any ideas on the best option these days?

A 2.5" external hard drive will hold MUCH more and still fit in a shirt pocket should you choose. Lots of storage for a reasonable price. Remember to make backups of whatever meda you choose. You don't want your files to be in just one place.

Options for file conversion

Hello,
I'm having difficulty putting old presets (CS5.5), the new version (CS6).
I downloaded the trial version, but only came fourth file conversion options, among them F4V, FLV, H.264 and MP3. Where did all the other options (MPG, AIFF, M2V and many others)??
I hope someone has a solution. Thank you!

AME gets installed through a host application. You probably got AME CS6 by installing Flash CS6? If so, Flash Pro or Design applications only support limited set of codecs/formats. If you install Production Premium and launch Premiere Pro, then go back to AME, you will get all supported formats.

EJB Design Pattren For File Transfer Application

hi,
My requirement is Transfer of large files (around 300-500KB) across the network with a central repository.We looking at a Solution from J2EE With EJBs.
At the Central Repository we are looking for ejb-Application Server. But the the issues i come acorss for my requirement are
1.I need to store and access Files on the local hard Disk with ejbs
>> But ejb spec won't allow to access the local file System
2.Based on the certain rukes i need to forward the files to different location
>> But ejb Won't allow to use Sockets in EJB.
I Want to know is there any work around in EJB to meet my requirements.
Any suggestions and ideas are welcome.
Regards
Srinivas

Thanks For Your Feedback. I Will Explain my Requirement more elobarate.
Our System Arch Looks like this
The Current System
|--MiniServ1--Client
Source---Central Server--|--MiniServ2 --Clients
| |--MiniServ3--Clients
Data Base
------ Bidirectional Link
Central Server --With database about all the transcations through the System
Mini Serv*--with Storage info of teh files came to that Server
Where Source / End Elients are Windows Based Clients(Developed in VC++)
The File Size Transfering across different Sources is of Size around 0.5 MB.At the Central Server these Files Will be Stored on the local hard Disk.At Centarl Server based on Some Rules it will be routed through different Mini Servers(Mini Serv*).Mini Server Will Send the file to different Clients. After Working on the files the files will be send back to the central Server via the Mini Server*.At the Central Server we have the latest Copy of the File
Currently Entire System Based on Windows and Central Server Built using COM Components Running on Windows 2000 Advanced Server.
The Problem
We Want to port the existing Sytem in java with out touching the Source and End Clients.We thought of replacing the Central Server with J2EE Application Serevr and COM Components with EJBS.But in Ejb we can't write to Local System and can't use sockets to send the files to MiniServers.
Is there Any Work Around for the mentioned problem using java?

Page Design Options for Microsoft HTML Help Output?

Hello, I am new to RoboHelp. I am almost done designing my first RoboHelp project (which has an MS HTML Help output). I see from my documentation that skins can only be applied to Webhelp or Flashhelp. However, i would like my help output to have a custom look. Is there a tool or method I can use to customize the look of my MS HTML Help?

I'm tempted to say "Yes. Use WebHelp" but there is also AirHelp to consider. You may want to check out this link.

Design options for interfacing RFC as Receiver

hello guys ,
Need some ideas in developing a scenario for interfacing RFC as receiver from a stored procedure call on DB side , what would be best and easy way to interface this RFC?
Best regards
Krishna

hi,
but what do you need to know?
you can call stored procureude with sender jdbc adapter
and put the data via RFC
it's better to use an abap proxy but if you cannot use the rfc
you don't need any BPM as this is a jdbc - rfc flow

Design option for view only AM

We are creating an ItemAM that will be opened, updated, and then closed. There will be two types of users that use this AM, those with edit capabilities and those with view only capabilities. Once the item is closed no updates are allowed, so the item will remain in a view only state. We are looking for some ways to model this. We want to maintain state when the ItemAM is opened by users with update responsibility. However, we do not want to maintain state if the item is opened by a user with view only. Once the item is closed we do not want to maintain state, since you cannot change the item. What's the best way to model this? Can a personalization be used to check the responsibility or item status and not save state when the item is brought up in view only mode? We anticipate that about half the time the item will be brought up in edit mode and the other half in view mode. I am looking for recommendations on the best way to implement this.

It is not correct to think of AM being update allowed or not, VO is the one that captures the updates and applied it to the DB via EO.
As far as your problem is understood, based on the responsibility, you either want the page/field to be update allowed or update not allowed.
For this , you can make the beans render as read only when the page loads based on the responsibility
or
you can always have the page/bean as update allowed and in the submit action discard the changes based on the selected responsibility.
Thanks
