"An IdocException occurred" while posting Idocs from SAP ECC to SAP PI AEX

Hi all,
While sending Idocs from SAP ECC to SAP PI 7.4 AEX, we are experiencing this issue at SAP ECC-SM58
Only a particular Idoc type is having this issue.
Below are the checks done before posting this query:
1. Pushed other Idocs from the SAP ECC to PI and all were getting exchanged successfully.
2. Reloaded the meta data in PI for  the particular Idoc type in issue.
3. Checked the RFC destinations in SAP ECC, RFC connection test is also working fine.
4. Unicode option enabled in the SAP ECC RFC destination pointing to PI-AEX
5. Restarted the inboundRA service in PI AEX.
Is there anything still missing. What could be root cause of this issue.
If anyone has encountered it before, pleases share the resolution.
Thank you
Younus

Hi Amit,
Thanks for the reply. Log viewer doesn't provide much help on the error.
The error desc says
"JRA]serverExceptionOccurred. Server XI_IDOC_DEFAULT_SID, Managed_Application_Thread_58, connectionId=5-ip address|sapgw20|XI_IDOC_DEFAULT_SID, Exception: com.sap.conn.jco.JCoException: (104) JCO_ERROR_SYSTEM_FAILURE: An IDocException occurred"

  • Error occured while posting the job schedule for JDBCAdapter

    Hi Experts,

    Any idea about this error?
    Tks in advance.

    Hi,
    After applying the SP 23 Patch Level 08, LOCK JDBC problems stopped.
    But now when a network error or database error, the JDBC Sender Communication channels that were open to connection, are blocked.
    Even following the instructions in [SAP Note 1083488 - XI FTP_JDBC sender channel stop polling indefinitely (04_04S)|https://websmp230.sap-ag.de/sap(bD1wdCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1083488] the problem continues.
    I've already set the parameter "taskTimeout" and selected the option "Disconnect from Database After Each Message Processing" but not resolved.
    Any ideas?
    Thanks in advance.

  • "...an error occurred while sending data from the iPhone" - caused by latest iPhone update today?

    I've been syncing my iPhone to my (non-apple) desktop for several months without difficulty.
    Today I accepted the latest upgrade to my iPhone software.
    Since it installed, it will not sync.
    It gives the error message "iTunes could not sync calendars to the iPhone "Steve's iPhone" because an error occurred while sending data from the iPhone."  After rebooting the desktop, the error repeats, and it's now in hour 2 of the continuing message "Syncing Steve's iPhone (Step 2 of 2) - Finishing sync"
    Has anyone else run into this Undocumented Feature of the latest upgrade?
    As bugs go, this is pretty serious for those of us who depend on syncing the iPhone and desktop for our business!
    Thanks to anyone who can help!
    Steve Callender

    Tried rebooting the phone, and now it works.
    Guess there's 2 lessons here -
    Boot again when installing new SW, even if the phone reboots itself during installation, and
    Boot to see if that fixes a problem before posting it.

  • Unable to interpret 1,000.000 as a number while posting IDOCs

    Hi All,
    I know this query has been asked multiple times but as of now I am unable to find the right match so posting this query again. We are posting an IDOC from SAP PI to SAP ECC using SAP PI IDOC Adapter. When the IDOC is sent there is one specific value in one of the fields which have value 1000.00. Now when the IDOC is received by SAP the value is received as 1,000.000. As far as I understand this is because the user configured in the RFC destination in SAP PI  (which sends the IDOC to SAP) is having in its default profile the Decimal Notation as 1,234,567.89 and hence we see the value as 1,000.00.
    But then the IDOC is not posted in SAP and the issue is: "Immediately processing not possible: Unable to interpret 1,000.000 as a number".
    As I am not much aware about ABAP being a PI consultant, would appreciate if experts can guide me on how to resolve this issue. Thanks for taking time to read through the issue.
    Thanks,
    Pratik

    Please check at abap end for the inbound parameters.
    In we20 the message type will be assigned .Double click it and you will get the process code.Double click that and you will get the required FM.
    If the inbound function module is Z ,Please do the necessary change.
    OR
    Else try WE19 to process the idoc (Existing).
    Execute and then check the Inbound function module option and then call in debugging mode to check the where the error is happening.
    Hope it helps.
    Thanks!

    Problem:
    I upgraded Leopard to Snow Leopard. Everything worked fine for a month. To free up disk space I deleted some of the iPhoto flders (modfied and original images). Everything worked still fine. Shut down the computer. Next day it was incredibly slow. At the same time the indexing was running. I stopped indexing, but stll slow. Every operation took minutes. I tried all the tricks that I found in the internet (repaired file permissions, repaired disk, cleared PRAM , moved big filed from desktop, etc.). After 24 full hours of trying all this I decided to erase the hard drive and reinstall, directly from the Snow Leopard Install disk, but it fails after downloading the packages. Below is the part of the log. Then I tried to use the old Leopard install DVD to reinstall Leopard, it then sais estimated time 12 hours or so and eventually crashed, spitting out a lot of "reportcrash" in the log. What is going on? I'm running out of options. Any advice? Would zeroing the hard drive help? If nothing else I plan to buy a new hard drive, since the only explanation I have is that there is a problem with the hard driven although the disk utility says it is OK. I need a bigger one anyway. Any ideas? Thank you!

    It sounds to me like your Internal Hard Drive is failing.
    I recommend you buy a new one, that is a good candidate for replacing the old one, but install it in an External enclosure and Install a fresh Mac OS X on it from the DVD. You can boot your Mac from any attached drive.
    The new System can be used to get some work done, check your emails, and takes the pressure off resolving this immediately. You can also attempt to salvage files off the old drive if needed.
    Once things seem to be working, then move the new drive inside the computer. Failures at this point may be due to bad cable, which has been a problem in some of these MacBooks.
    Use security erase, write Zeroes, one pass, to re-write every block on the old drive. Any block discovered to be bad will be replaced with spares the drive holds in reserve for this purpose. If more than 10 blocks are pared on one pass, "Initialization Failed!" will be the result. Although you can try the erase again, there is some question whether you want to trust this drive with your precious data.

  • Get "An Error occurred while retrieving data From ProjectWebApp.." when searching content on an External Content Type

    I have set-up an ECT in SPD2013 on SP2013.  It is a SQL Data source called ProjectWebApp.   I have BCS/SSS set-up.  I can create an ECT OK in SPD.  I can add the ECT to a custom list.
    The problem is when I add a new item in the list the following error message appears in red
    An error occurred while retrieving data from ProjectWebApp. Administrators, see the server log for more information
    I cannot filter or return any results.  There is data in the DB.
    Another test I do is to try and create a new App/List using the "External List" template.  When
    I select the ECT a red message appears "External Content Types are not available".  which is odd since I can add an ECT to a list as mentioned above.
    Any ideas?

  • Error occurred while downloading files from Administration Server...

    Hi guys,
    If i already have my application deployed and exploded in ../tmp/_WL_user , when I restart the managed server it will try to download again the files from the upload directory in the Administration Servers? (I'm using stage mode).
    Sometimes I got the following error:
    Caused By: java.io.IOException: [DeploymentService:290066]Error occurred while downloading files from Administration Server for deployment request "0". Underlying error is: "null"
    and I already have the war exploded in /tmp/_WL_user
    the staging mode is not only for the first deployment? when i don't have the war exploded in /tmp/_WL_user?
    I've some confusion related to the process or deployment/startup of the managed servers.
    Thanks

    Hi,
    when you get following error * DeploymentService:290066 * then that means
    A service on the machine is preventing the WebLogic Server remote instance from downloading the configuration file. This can be Hosts Intrusion Prevention (HIPS) agents or any other agent causing this issue.
    Disable the agent interfering with the download process to fix this issue.
