XI-Multiple instance scenario -File & SQL sender communication channels

Hi
i have a basic question regarding how file sender communication channel ( where we poll for a particular file pattern either using file/ftp types in a particular subfolder ) or a sql sender communication channel - ( selecting records from a sql source ) would work in a scenario with two active XI instances and j2EE file and sql adapter services running on both of the J2EE servers ?
1. How would the file polling from both J2EE servers - avoid a conflict looking for the same file pattern ? Is there any inbuilt mechanism from SAP to make multiple instances work with the file polling - without a confict ?
2. Simlar question for SQL sender type communication channel ?
If SAP does have a mechanism to handle multiple instance scenarios for file and sql sender adapter based communication channels, is there a link/document on this ?

Hi Karthik,
Please see my comments.
I am just wondering aloud - what will happen if we use a select for update clause in the sql sender adapter communication channel -
Gouri: Yes you can use select + update. In fact that is the right way.
will this ensure that polling from one J2EE instance will lock the selected records so that the second instance does not select the same set of records from the sql server ? Or should we not use a select for update and use a simple select statement ?
Gouri: Yes. SQL DB will ensure that same data will not be picked by another node. As I mentioned earlier use serilizable option from advanced mode.

File Structure - Sender Communication Channel

Hi All,
My Sender flat file structure is below like this
Filed1|Field2|Field3|Field4|Field5|Field6
Filed1|Field2|Field3|Field4|Field5|Field6
Filed1|Field2|Field3|Field4|Field5|Field6
Filed1|Field2|Field3|Field4|Field5|Field6
Filed1|Field2|Field3|Field4|Field5|Field6
Filed1|Field2|Field3|Field4|Field5|Field6
I did the Sender Communication Channel configuration - Content Conversion
Document Name : XXX
Document NameSpace: XXXX
Recordset Structure: MT_Test,*
Recordset Sequence: Ascending
Key field Type: String Case-Sensitvie
MT_Test.fieldNames: Filed1,Field2,Field3,Field4,Field5,Field6
MT_Test.fieldSeparator: '|'
MT_Test.additionalLastFileds: ignore
MT_Test.endSeparator : 'nl'
ignoreRecordsetName: true.
But its pick the file, In SXMB_Moni show Currect...
But in Runtime workbench, in Communication Channel moni, it show below like this,
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_Test xmlns:ns0="http://XXXXX">
<JOBS />
</ns0:MT_Test>
What is the Issue, where i missed some thing, In message mapping, its correct..
Thanks.
SR

SR,
I am still little confused with your below statement.
But its pick the file, In SXMB_Moni show Currect...
But in Runtime workbench, in Communication Channel moni, it show below like this,
>
> <?xml version="1.0" encoding="UTF-8" ?>
> - <ns0:MT_Test xmlns:ns0="http://XXXXX">
> <JOBS />
> </ns0:MT_Test>
You mean to say that in MONI, the mapping output is fine, but when you check the output at RWB -> CC Monitoring for the Sender Channel, then you get the above mentioned XML?
This means that there is nothing wrong with your source CC settings. If the entry in RWB -> Sender CC is wrong, your MONI entry will never be right. So, this is really weird.
What is the source structure that you have defined in DT?

Neetesh

Issue while archiving the processed file in sender communication channel using SFTP adapter

Hi All,
In one of my scenario (File to IDOC), we are using SFTP sender communicationchannel.
we are facing an issue while archiving the processed file. Some times PI processed the file successfully but unable to archive it and in the next poll PI process & archives the same file successfully which will creates duplicate orders in ECC.
Please let us know how to resolve this issue.

Hi Anil,

Regards ,

1. Check PI id and password is working fine.
Check if the user you are using has SAP_XI_APPL_SERV_USER role.
Another way is to pass id and pwd in URL
Try to pass the User ID and Password in the URL( the URL which is given to the webservice).
Example: http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel &sap-user=xxxx&sap-password=xxxx
2.Provide SOAP URL like -
http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel

Using common SOAP Sender Communication Channel.

Hi,
Env: PI 7.1
Scenario: Same SOAP Sender communication channel is used in more than one scenario.
Properties "Use Encoded Headers" and "Use Query Strings" are checked.
Problem: SOAP channel is getting binded with the first interface/call. Subsequent calls from other interface proxies fails. It always shows the interface which used this channel for the first time.
My aim is to use the common channel in multiple scenarios and do not want to create separate channel for each.
This was working fine in PI 7.0.
Please help.

A workaround would be creating multiple sender agreements using the same channel. For this while creating the sender agreement, use the option "Sender uses virtual receiver". This was u may use same set of sender service and sender interface with same channel.

Prateek

BIC Module Error in Sender Communication channel for EDI to File scenario.

Hi Experts,
We are working on the EDI based scenarion where EDI files come to SAP PI from partner and then through Split 997 Adapter Func Ack is sent back to the Partner . But we are facing a issue in our sender Communication Channel which is a File Adapter Channel and uses BIC Module for the conversion of EDI to XML .Request if any one can provide any guidance on the below issue coming in sender CC.
Error: Error in BICMODULE-module:Temporary error: BIC XI Adapter call failed. Reason: 2 errors occured. First error: EdiSegmentData read(): Edifact Format not correct : segment must end with \"segment delimiter\" (Segment : ISA). DESCRIPTION: EdiSegmentData Error: Your Edifact Format is incorrect the segment must end with \"segment delimiter\". check segment [not specified]. Last error: InhouseDocReader moveNext(): com.seeburger.jucon.dochandler.AnsiX12DocReader, offset[92(read Segment : ISA)]: could not parse segment (wrong format): EdiSegmentData: Edifact Format not correct : segment must end with "segment delimiter" (Segment : ISA) DESCRIPTION: InhouseDocReader Error: [not specified] at position [not specified] could not parse the segment [not specified] Error while reading description - wrong format.
Thanks & Regards,

Hi Abhishek,
Is there any special character present in the EDI file?
the parser is not able to parse the data.
you can check the BIC conversion log for more information.

Problem with Sender File Content Conversion Communication Channel

Hi All,
I am using XI 3.0--SP 16.
I have configured a Sender communication channel with File Content Converison which takes up a Fixed length text file and converts to XML.
My scenario is that I have some 'n' files, out of which one file has error in content conversion.
In a normal scenario I would expect other files to get processed, but they are not.
I can correct the error or even discard the error file. But I am unable to understand why XI is not processing the rest of the good files.
Thanks in advance.
Regards.,
Sudharshan

Hi,
@Renjith
The QOS is EO, thats why I am wondering why it is not picking the rest of the good ones

Files not getting picked up using Sender Communication Channel frm MDM sy

Hi Experts,
XI sender communication channel is configured to pick up any files coming from MDM system from the following path
/XXX/XXX/mdm/mds/XXX/XXX/Material_Master/Outbound/P33/P33_R3_PORT/Ready
Earlier we had the scenario working properly that created idocs in R3 system.(MDM>XI>R3)
Currently i tried to test the scenario again but i don't see an entry in the sxmb_moni or tried checking whether the sender communication channel is working properly it showed polling correctly in RWB.The files are already sitting in the the above path.XI should be picking it up but don't know what the problem is?
I also tried a test in RWB>Integration Engine>Test Message put the payload and it was able to create idocs in R3.So i concluded there is an error in picking up message from MDM.
Is there any log available for the commmunication channel where i can see error info of whether any files picked up or not.
Please suggest me what all can be done to to ensure the CC is picking up the files.
Earlier responses highly appreciated.
B'Rgds,
Sudhansu

Hi,
In addition to the RWB channel check suggested by Aamir, you should also check if the channel is
1) Active in ID
2) Channel is not locked in VA, if it is locked then your status in RWB will show processing started but the files wont be picked up...for more details check the unlocking procedure mentioned in this thread:
JDBC Sender Adapter - NOT FETCHING RECORDS -PROCESSING STARTED
The unlocking procedure is the same for FILE and JDBC....

Sender Communication Channel for Integration Scenario IDoc - XI - IDoc?

Hello All,
One general question. I have to configure an IDoc - XI - IDoc Scenario. For this Scenario I have to configure an Receiver Communication Channel (IDoc Adapter) to the Backend System but what about Sending Communication Channel for the Sending R/3 system.
Is the (IDoc) Communication Channel from Sending system to XI required to configured?
Many thanks in advanced!
Jochen

Hi Jochen,
for sending IDOCs from SAP to XI, sender IDOC adapter is not required. when XI will send the IDOC to a SAP system, then receiver IDOC adapter is needed.
Thanks,
Rajeev Gupta

Inactive Sender Communication Channel still processing Files?

We de-activated the Sender Communication Channel of an interface. However, the file adapter keeps processing?
Anybody know what is going on?
Thank-You.

Hi Tom,
1) Check out Whether you have De-activated the Right Adapter.
2) Refresh the Cache,
a)Start transaction SXI_CACHE.
b)From the context menu XI Runtime Cache select Start Complete Cache Refresh.
c)Call transaction SM58 to check the status of the refresh process.If no entry for function module SAI_CACHE3_REFRESH_BACKROUND is Present any more the cache update is finished.
If you still face issue try this .
Many actions require to access System Landscape Directory content from the Integration Builder. To optimize performance, this content is loaded into a cache so that the System Landscape Directory does not have to be accessed directly each time that System Landscape Directory content is required.
However, this cache is not automatically updated if changes are made to the content of the System Landscape Directory. For this reason that we delete the System Landscape Directory cache if changes have been made to content in the System Landscape Directory. The cache is then filled each time that the System Landscape Directory is accessed. If we log on to the Integration Builder after we have made a change in the SLD, we do not need to delete the SLD cache.
To clear the SLD cache, from the Integration Builder main menu, choose Environment ® Delete Cache for SLD Data.
Once we have deleted the cache for SLD data, accessing objects in the SLD may take longer than usual initially.

PI sender communication channel not reading files from NFS directory

Hello,
I have a sender communication channel configured to read file from NFS directory which is on ECC server. A program in ECC generates the file and puts it on the ECC server in the output directory. PI sender communication channel is supposed to pickup this file and process it. If I give the NFS path as the source directory, I am getting error: Configured source directory '//Server/DIR/OUT' does not exist. I tried putting '
Server\DIR\OUT' too but same error. Do I have to add the NFS path of ECC into PI as logical path?
Any suggestions?
Thanks,
Sangita

Hello Sangita,
Your ECC server is an external system, therefore you need to activate FTP service in that system and use the transport protocol FTP:
http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
You can use NFS protocol when you have a local directory in XI server.

Ok now I get your requirement.
you cant achieve this - how one receiver channel can put in two location if you dont have a dynamic configuration defined i.e Adapter specific attributes.
easy way - involve IR mapping
else
have a adapter module to define your dynamic configuration.
Ref: /people/daniel.graversen/blog/2006/10/05/dynamic-configuration-in-adapter-modules & /people/michal.krawczyk2/blog/2006/10/09/xi-dynamic-configuration-in-adapter-modules--one-step-further
Set the dynamic directory/file name etc for your receiver adapter.

FILE SENDER COMMUNICATION CHANNEL DOESN'T GET FILE

Hi,
I have create a new sender communication channel with ftp file configuration. Server parameter and source directory are correct.
I have also checked file and directory permission (chmod 777)
Poll interval is 600 secs.
There is no error in communication channel monitor (returned log: CC is correctly configured and started).
Process started every poll interval, but no file is picked up.
Why?
Carme

Hi,
What type of file are you processing. Check whether the file type is binary or text mode.
Also check whether the file name you have specified in the CC and the exact file in the directory are the same.
Also check the file processing mode, whether it is read only, delete or in test mode.
If the file is in read only mode when the file first processed, then once the file was processed it would be in read only mode, so if you place the new file it should process, so try deleting the existing file in the directory and place a new file with exact file name along with the correct extension and try to process it.
Also I would suggest you check the exact file extension, by unchecking the radio button in the folder option under the menu tools> Folder options> view-->hide extension for file type.

File sender communication channel stop working

Hi Guru,
I have a file sender communication channel. It usually works good. But sometimes it just stop working. And In RWB, it shows no error. If I stop it and restart it in RWB, it immediately works again. This happens once a while. Any ideas?
Thanks,
Meiying

Hi,
option 1--
Do some dummy changes and activate channel and try and perform cache refresh.
If still not working then stop and restart SFTP service,if still no luck then restart JAVA stack
option 2
try to put timeout value in the channel.
Regards.
Mastan

File sender Communication Channel is not working

Hi friends
we Created File sender Communication Channel and Activated but It is not picking up file
1. 0 messages in Message Monitoring
2. My Communication Channel not appearing in Communication Channel Monitoring also
3. We have refreshed the cache and activated the channel.
we chack with File name, Directory name and path ....
Friends have any idea

Perosnally, I would recommend setting a trace and letting the system telling you exactly why.
Traces are used to analyze runtime errors. By setting a specific trace level for specific locations, you can analyze the behavior of individual code segments at class and method level. This is done with the help of the log configurator service:
Log onto the Java Admin Console
     Services
     Log Configurator
     Locations
     Choose the location (Java package) and the tracing level (severity)
(for example, com.sap.aii.adapter.file)
     Root Location > com > sap > aii > File
     Set the severity and choose Copy Severity to Subtree
