Issue with generic extraction using FM

Hi All,
I am trying to load from one DSO to other DSO, where i am trying to use generic extraction using FM, where i created strucutre of second DSO .
created Generic datasource with Function module.
when i am loading data using infopackage, its loading perfectly into PSA(with 100 records) and when i am loading thru DTP to Data target( second DSO), it is looping many records in each datapackage(like 8 million in each package) and updating into datatarget finally 100 records. but it is taking long time to finish the process.( i copied RSAX_GET_SIMPLE_DATA) and added transformation logic to it .
so i would like to know, if there is anything i have to change in the Function module code, to fix this.
i would also like to know,  request is already in PSA, will it again extract from FM, when updating thru DTP.
Thanks
R,man
Points will be awarded.

Hi
I also had the same process. In the code of the function module. just check the Raise Exception code, probably ABAP guy can help. Also try to debug the code in RSA3 in debug mode. Actually it is going to a infinite loop, I guess.

  • Issue with generic extraction (Generic Delta)

    I have one more issue with Generic Delta Extraction. Here I selected the field related to my requirement but when I am trying to save I am getting error Still OLTP have errors.
    I need some help when we select generic delta wht are the settings. Like now I am working on Inventory Management.

    Hi ,
    I think there are some of the Keyfigure fields which needs 0Unit or 0Currency field to be present in the Extract Structure but they are not present . Check All unit of measure and Currency unit fields are not hidden .

  • Generic extraction using table

    Hello friends,
    We have three methods in Generic extraction, as we know.
    1. Using view/Table
    2. Using FM
    3. Using Infoset Query
    I know pretty well the extraction using View, but when do we use "Table"?
    Is there a specific method to perform generic extraction using TABLE?
    Please clarify

    Thanks for the replies.
    In case of a generic extraction with view, i've followed the below procedure.
    1. RSO2.
    2.create a generic datasource by giving a view name and selecting the fields for selection criteria, save and generate.
    3. replicate data sources in BW.
    4. create an infosource and assign the data source, mapping and create an infopackage to load data.
    Now ,
    1. how do we enable Delta for this method?
    2. Is  this possible at all? if yes, how?
    3. How do we proceed after the replication of DataSources in BI? specifically, procedure in BI?
    Pls clarify.

  • When to go for generic extraction using view and infoset query?

    Hi,
                        Can anyone clarify me when we should go for generic extraction using view and when we should go for generic extraction using infoset query....
    Also what is the difference between view and infoset?
    I tried but could not find out....
    Regards,
    Kalyani.

    Hi Kalyani,
    We normally go for View or infoset when the data to be fetched in BW is distributed in different tables in SAP R/3.
    Had the data been available in one table we can easily build our datasource on that table but if there are more tables then its not possible to do it without Views or Infosets. You can use Function Modules to build your datasource in case it involves complex logic to figure out the data from various tables.
    Depending upon the table relationships we create view and include various fields from these tables in that view. Same is with the Infosets, you can have more flexible options like Outer Join, left outer Join etc.

  • Anyone else having an issue with TCP connections using iCloud for Windows?

    Hi,
    Before I asked this question, I did wait to see if any related questions came up, but none did, so I submit it now.
    On my admittedly older laptop running Windows 7 64b Home, I've run into difficulties with the iCloud for Windows app to the extent that I had to uninstall it.
    It would that, as my laptop was running, in the background, iCloudServices.exe would endlessly iterate TCP connections, which, while not actively sending or receiving any data, after some hours would number over 100 instances, taking up resources, and grinding my laptop's WiFi connection to a grindingly slow pace. I ended up, within the app, turning off everything, iCloud Drive and Photos, (I never used bookmarks), but still this would continue to occur.
    I contacted Apple Support, explaining what was going on, and they stated they only dealt with IOS and gave me a Microsoft Support number. When I called Microsoft support, I came more and more to the realization that the issue was specifically with the iCloud for Windows app, as that was the only software that was endlessly creating and not closing TCP connections as it was. How was Microsoft supposed to solve an issue with Apple code?
    So I called Apple back, whereupon they insisted it was a Microsoft issue. I explained other cloud services installed on the same computer were not having the same issue, it was unique to ICloudServices.exe. They stated they only dealt with IOS. I stated I purchased an iPad Air less than 7 months ago, and was trying to run iCloud in support of that.  They again stated they only dealt with IOS, and suggested I again try Microsoft. I asked them if it was reasonable to expect Microsoft to solve issues with Apple code? They said regardless, there was zero support offered for anything having to do with Windows, and all I could do was uninstall the app, which I did, though that did not feel very satisfactory to me. My thinking is, if Apple writes a Windows app in support of their hardware, they should offer support for it.
    Anyway, I was just wondering, is this an issue unique to me? or have others experienced a similar issue? I found this issue by opening the Windows Resource Monitor, looking under the Networking tab, and scrolling through the TCP Connections section to find 100+ concurrent iCloudServices.exe instances listed, whereas even Chrome, with multiple tabs and extensions, topped out at around 20.
    My one month old Desktop, DYI, sports a solid Asus 1150 MoBo, i7-4790k cpu, 16GB Ram, and an EVGA GTX 970 video card. I list some specs only to illustrate this computer has no hardware issues in comparison to my long in tooth laptop. On this desktop, running Win 8.1 Pro 64b,  at least as many, identifiably Apple, background service TCP connections are created even compared to Chrome, regardless of many tabs being open, many extensions, and even some related apps. Adobe does not even come close, though I run the full CC subscription. On this new computer, running Windows 8.1 Pro 64b, there are currently over 50 TCP connections and loopbacks that do not identify themselves, with just a - for the Image, and PID. With the experience on my laptop, I wonder how many of these are generated by Apple software, if not specifically iCloud software?
    The frustrating aspect of these connections is they seem in no way active, While the Chrome and Adobe connections can be seen to be transferring data, as long as I am not running iTunes, or so have my iPad actually plugged in, it seems 99% of the time these iCloudServices.exe connections are just taking up ports, neither sending nor receiving any data discernable to me under the Processes with Network Activity, or Network Activity lists, both displayed in the same window as the TCP Connections in the Windows Resource Monitor.
    Though I am fairly ignorant as regards coding, it seems as if there is no call to close a connection, very specifically, iCloudServices.exe, when it is no longer needed, and the next time a connection is needed, a new one is opened, rather than accessing the one previously opened. The only other reason I could imagine this might be occurring is if my Norton Internet Security software might mask and/or block the port after a certain time of inactivity.
    Anyone out there have any ideas or advice about this? Thanks in advance.

    Thanks jared,
    I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
    So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
    Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
    For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.

  • Issues with pagination when using Adobe table with Web dynpro for ABAP

    Hi All,
    I am facing strange issue with table text.
    I have three cols in table, one is of type Char255 and other two cols are of type string.
    The text in the col 1 is displayed perfectly but in other two cols of type string whenever we have pagination the text in table is getting truncated and in next page new row starts.
    Could you please tell me the settings that will enable flowing of text in the row of table to next page.
    Thanks,
    Arti.

    Check the properties of the text field you use for those columns (if you want to control it on this level) or check the same attribute for the row subform (one level up control): "allow page break within content".
    Regards Otto
    p.s.: we all have deadlines... and manage to pay something back. Think about it.

  • Issue with SaveAs PDF using XSLFOP

    Hi, We have been using SaveAs method to generate PDF files using XSLFOP technique successfully, however, recently we ran into an issue where a very large report (about 100+ pages) generated a PDF file that could not be opened. We get the following error when we try to open the PDF file. “There was an error opening this document. The file is damaged and could not be repaired.” We tried it again with lesser range of dates and the proper PDF file is generated. (Report was about 35 pages). So we think it has something to do with the large volume of data which is causing the SaveAs method to generate the corrupt PDF file. Any help will be much appreciated !! Note : In the same folder where we have the EXE,PBD and DLLs, we have two subfolders fop-0.20.5 and jre. Thanks, Chirag Vora

    Hello Chirag,
    We submitted this problem to engineering 10 years ago with PowerBuilder 9 !!!
    It appears to be a problem with the FOP processor which needs a large amount of memory to complete the task. You can find similar issues with other tools than PowerBuilder:
    The oXygen-user October 2003 Archive by thread
    As a workaround, you can save the data in XSL-FO format within PowerBuilder, then use the fop.bat file in the \Shared\PowerBuilder\fop-0.20.4\ folder to convert it from outside PB.
    This will still give you the memory error until you modify the batch file to increase the maximum heapsize for java.
    In the fop.bat file change the java start command to : java -Xms64m -Xmx256m ...
    The option -Xms definies the initial heapsize for the java engine and -Xmx the maximum heapsize.
    We believe the default maximum heap is 64MB and this is what it is running into (or running out).
    Setting it to 256MB with -Xmx and it was able to complete
    HTH,
    Jacob

  • Issues with Japanese encoding using Mail

    Since recently (I would say since I updated to 10.6), I have an issue with Japanese-encoded (ISO 2022-JP) mails on my English MacOS.
    I have no problem to read, edit and write answers to any mails.
    However with some ISO JP-2022-JP encoded messages (sent with Thunderbird 2.0.0.23 (Windows/20090812) btw) I have the following misbehaviour:
    - if I send the message and let the encoding to "automatic", Mail sends the mail in UTF-8, which I do not want since most of Japanese computer do not understand UTF-8 by default (and the receiver gets panicked: "I can not read your mail T_T !")
    - if I set the encoding to "ISO JP-2022-JP", I can not send nor save the message (see [1] at the end of the post). One should note that the error message when saving is really misleading (and yes my hard-drive has a lot of space left) and it should be fixed by Apple.
    - if I dig a bit deeper, I can in effect find some characters in the original message which prevent Mail to send my mail. It however does not make any sense since:
    - those char were in the original message properly encoded in ISO JP-2022-JP
    - those char are always very common ones
    The only solution I have found so far is to delete the original message in my mail, which is very frustrating...
    A sample of such mail can be found at (I removed personal info. and the mail is about a drinking party):
    - http://files.me.com/trouve.antoine/73w3w9
    Help would be very appreciated.
    Thank you very much.
    Antoine
    [1] I get the following error messages:
    -> try to save:
    *This message can’t be saved to the Drafts mailbox.*
    The message contains one or more attachments that
    are too large to be saved in the Drafts mailbox. Try
    deleting some attachments.
    ->try to send
    *Invalid Text Encoding*
    Some characters in your message could not be
    converted to the “Japanese (ISO 2022-JP)” text
    encoding. Choose a different encoding from the
    “Text Encoding” menu.

    You can find out about the different versions here, for example:
    http://en.wikipedia.org/wiki/ISO/IEC_2022
    Thank you. I feel a bit stupid for not having looked in Wikipedia at first...
    I sometime wonder how could such basic problem like charset not being solved after more than 40 years of computer science...
    Here is a note that addresses that problem, but I don't think it works with 10.6. Might be worth a > try:
    http://discussions.apple.com/thread.jspa?threadID=121808&tstart=60
    Thank for the link.
    It seems to still work: new japanese mails are now sent in "ISO 2022-JP-2".
    However, for messages with the header explicitly specifying "ISO 2022-JP" (which should be "ISO 2022-JP-2" on my mac) it has no influence.
    The only ways I see to solve this issue would be:
    i) to force "ISO 2022-JP-2" for all mails (a bit too extreme)
    ii) to force the use of "ISO 2022-JP-2" instead of "ISO 2022-JP", but I do not think such precise configuration is possible
    This mess appears to be due to Thunderbird which seems to mix "ISO 2022-JP-2" and "ISO 2022-JP", but I do not have any working Thunderbird to test now...

  • Issues with iMac freezing using Mail, Safari, Chrome

    I'm having issues with my iMac freezing, forcing me to hard restart my computer each time. I think I've had to powered down via power button altleast a twenty times today and yesterday. I've restarted 4 times just trying to finish this post
    It seemed like I was only freezing using Safari at websites like facebook and youtube.com. So I switched to Chrome, which lasted a few hours until I started freezing on that as well.
    I logged on as a Guest account and they seemed to be working fine. I thought Flash may be the issue so I re-installed but no dice. I emptied cache, cleared history from each browser, etc -- no help.
    Then today I started freezing just using mail. While typing a message, auto correct attempted to correct a word and my system completely locked up from that.
    I have plenty of hard drive space, RAM isn't an issue either.
    Here's some of my system log just before one of my recent freezes:
