Dynamic Web Interfaces XMLHttpRequest

hi all I wanted to say - I found the XMLHttpRequest and the bus. users love it as pages refresh faster .
Using it a lot where data in fields ahead depend on choices made earlier in the page ( like when user chooses a country and we need to show cities of selected country in the next drop down)
Added benefit : it un clogs the network as less bytes passes from server to the browser/client.

  • URL dynamic in web interface

    Hello,
    I have created a planning cockpit for the endusers to access the web interfaces I created from a single web interface using URL's.
    I would like to know how I can get the URL dynamic as I have to transport this to the production system, having a different server name and port.
    Gert

    Hello Gert,
    I am exactly looking for a FM like that. I would like to integrate a BW web report in the GUI planning folder using a function button. When pushing the button, the web report shoud open in IE. I thought the standard FM like "HR_ULR_CALL_BROWSER" would work, but I don't know how/where to enter the URL as Input parameter (except for copying the FM and creating for each report/url a different FM).
    Could you let me know your solution?
    thanks a lot,

  • Query in BPS Web Interfaces - Open in New Window

    Hello,
    I am trying to insert a BW Query into a web interface but have it launch in a new window.  I know how to have it open in the web interface by using a text box.  In July of 05 I found an answer from Marc Bernard on a similar topic, but with a query returning variables.  When I tried to use the code, I got an error.  I know that I can create a URL with Target="_Blank" but I don't want to hard code the full URL of the web report because the default host and port will change with the systems.  I tried the following URL in hopes that would inherit the system but it doesn't work.
    http://<default_host>:<default_port>/sap/bw/BEx?cmd=ldoc&infocube=EPABUDGET&query=EPA322BR
    Here is the code I have for the report.   Can someone tell me how to open in a new window or how to get the URL to work?
    <iframe
        id="BWReport01"
        name="BWQUERY"
        src="/sap/bw/BEx?cmd=ldoc&infocube=EPABUDGET&query=EPA322BR"

    Thanks,

    Hi Cherie,
    you are on the right track. Just use a href="/sap/bw/bex..." target="_blank". If you need the URL to be more dynamic, use javascript with window.open.

  • Dynamic user interfaces

    Hello,
    here's a little teaser for user interface experts out there:
    I wonder what kind of techniques ABAP offers for creating dynamic user interfaces.
    When talking of 'dynamic' I imagine something like an arbitrary number of 'containers' where other programs (classes f.ex.) can draw their own user interface into.
    In Java this could be realized with the container concept in swing.
    I have done some research on this topic and the results are so far:
    a plain dynpro: seems to have no dynamic at all -> not an option
    a plain dynpro with a tabstrip: in case the number of tabs CAN be set at runtime AND the subscreens CAN be drawn from inside separate classes -> a definite option otherwise not an option
    any kind of web-frontend (BSP, JSP etc.): web-frontends are not allowed by company restrictions -> not an option
    dynamic documents: I could not find many information on these yet (also not on sdn). In case that an arbitrary number of parts of the dynamic document can be created from inside separate classes -> an option otherwise not an option
    I will be happy about any further information on this topic.
    Best regards,
    Patrick Baer

    I spent some time today doing research on BSP's and built a "BSP-Viewer" embedded into the SAP-GUI. Though I like the concept of BSP's a lot (like I did already with JSP's) but company restricitions are too strict. So BSP's are out of the play.
    After the discussion I started to play around with the different containers and basically I'm quite pleased with them and the "cl_gui_container_bar" allows an arbirtary number of "subscreens" which matches my requirements.
    But as usual there's still a downside:
    I found no option to built text labels and text fields into a container. Unless this is possible I can't give this approach a chance. I already found some postings which seemed to confirm that this is in fact not possible but I can't really believe it. At least from what it looks like it seems to me that the object navigator utilizes both: splitters, containers and all the stuff AS WELL AS the "classical" elements like text boxes, labels and so on.
    Any ideas on how to combine the container concept with text fields, labels maybe whole dynpros or subscreens ?
    Best regards,
    Patrick Baer

  • Content Library / Web Interface - access issue

    BPC Microsoft 7.5 SP6
    Windows 2008 R2 server
    We have puublished an Excel template as an HTML page to allow (web only users) access to a menuing system and have subsequent access to their individual reports in PDF format. The menu page comes up without errors but I encounter the error "You don't have access" when clicking on a menu option (cells within template). The cells contain an Excel Hyperlink function in conjunction with a EVBNV function to launch this report. (No BPC or excel errors exist within template)
    We have created a virtual directory for BPC application in addition to Reports and ReportServer for Reporting Services. We have modified the Site Settings and Folder Setttings in Reporting Services configuration to allow web users to correct role access.Users can access Reporting services Report url without a problem but the web interface does not want to launch/retrieve a pdf file. We have the correct BPC task capabilities and task profiles assigned, insuring they can access and use the content library.
    Thoughts?
    Thanks in advance.

    It appears there is an issue with EVBNV formula and its ability to dynamically pass parameters in HTML format.

  • Web Interface u0096 Characteristic u0093not indicated with comment facilityu0094.

    Using the Wizard, I have created a Web Interface based on a working Planning Folder.
    When I attempt to generate the Web Interface, I get the following error message :
    “Characteristic <i><b>( name assigned to the Web Interface )</b></i> is not indicated with comment facility”.
    Performance Assistant instructs me to “Indicate the characteristic as ‘commentable’.  You make this setting with the transaction UIBW”.
    No processing occurs.  There is no online help to explain this further, and transaction UIBW is ‘unknown’.
    I can ‘Display Preview’ the Web Interface, although I do get a pop-up indicating that there is ‘No executable version available’ and allowing me to set up Dynamic Preview.  The results Preview results are consistent with those reflected via the SAP GUI layout.
    Has anybody experienced this before ?  Have I missed a step ?  Any insight or help is greatly appreciated !
    Thanks,
    Lyle

    Hi Lyle,
    1) It must be understood that the Message points to the characteristic that you "somehow selected" before this error message came up.
    2) Please make sure that the Characteristic which you tried to change/set property ("before error message flashed") has document property activated and <b><i>is not compounded</i></b>.
    3) When the InfoObject is compounded, you need to activate the document property of the "InfoObject(s)" listed in the last tab of InfoObject Maintenance (Compounding tab)
    4) I was able to find out one OSS Note which describes the point (2) and (3). You could also check out and justify if it is applicable to your SEM-BW Version.
    <b>OSS Note Number - 580581</b>
    5) What you could also try is to create a document manually to make sure things are OK!
    5.1) Execute the TA - UIBW or RSD3 and enter the Characteristic.
    5.2) Select the Menu entry "Jump->Documents".
    5.3) Create a simple document and save things.
    I am not sure whether you would mind sending me the screen shots ( Screenshots embedded in PPT or WORD, Zipped?) of Object property (Characteristic which caused all this), characteristic adminstration tabs, compounded characteristics administration tabs at [email protected] (Only when the above points dosen't help you out)
    Thanks and waiting for your feedbacks!
    Good Luck!

  • Integrate WAD 7.0 Template into BPS Web Interface

    Dear all,
    We recently migrated to BW 7.01. We have an existing planning application running as a BPS Web Interface.
    I now want to integrate a query output (data and chart) by using a web template designed with WAD 7.0 into the existing BPS web interface. I know how to do this with a web template designed with WAD 3.5. There is also a How-to paper available that explains it for 3.5. I'm struggling now to do the same with WAD 7.0. The syntax for the URL generation changed, that's one problem. There maybe more when actually calling the web template from the web interface(?).
    I found some threads here in the forum dealing with this issue but no clear solution. Some posts even mentioned that integration of 7.0 web templates into BPS web interfaces is not possible at all. I would appreciate any information on this issue.
    Thanks in advance!
    Regards,
    Ulrich Meier

    Hello Ulrich,
    the 7.0 web templates run on your BI Java server which has a different host name (and port) than you BW ABAP server which run the BPS web interface. The servers are different in Dev/QA/Prod so you need to generate the URL dynamically.
    One way is to hardcode it in JavaScript. Something like: if CurrentDomain = ABAPDevDomain. Domain = JavaDevDomain. if CurrentDomain = ABAPQADomain. Domain = JavaQADomain. etc
    A fancy alternative would be to put the Java domain and port into an exit variable which you could include in the BPS web interface (in a hidden DIV tag for example). Fill the exit variable using function RSWR_GET_DEPLOY_PORTAL_INFO. Then your JavaScript can pick up this value to generate the proper URL for the web template.

  • Problems access to a web application (Web Interface or Web report)

    Hi,
    We found problems with the access to web application. Some users have problems with direct links to the web applications(Web Interface or Web reporting), when they click on the link an error message appears, the message displays the following text:
    "Cannot open file Bex?sap-language=ENbsplanguge=ENcmd=idoc_TE.."
    Clicking in details the message is "No Access to specified file"
    For this users the access to excel reporting is correct, the message appears when they click on the direct web links through the browser or directly in BW system, but if they type the URL they can access. Other users can use the direct web link without problems.
    I highly appreciate any help or idea about how to solve this issue.
    Thanks in advance.

  • Unable to capture trace, when user logs in throuigh Web Interface

    The Trace shows 'No Records Found', when user logs in through Web Interface of CRM. But there is Trace found, when the same user logs in through logon pad and carries out normal actvities.
    sufficient auth. is provided.
    Is there any setting in ST01, through which i can get trace , when user logs in through Web Interface
    Regards

    ST10 traces 1 instance only.
    Your CRM web interface could use another instance than your backend. Go to transaction SM21, choose the appropriate server and run ST10 again.
    Succes!

  • LIST OF VALUES not Populating in BPS WEB INTERFACE ( LAYOUTS )

    Hi BI Guru's
    I have created a WEB interface for BPS in BI ( version 7.0) .  But when i execute this in internet explorer, I do not get the LIST OF VALUES for Material. 
    When I click on "input help" the system open a new window for "Value selection".  When I specify the material code, it gives me blank LIST OF VALUES.
    But it is working for other fields like Customer, UOM in the same layout.
    Please suggest some solution.
    Thanks,
    Nilesh Labde

    hi,
    Thanks for the reply.
    Master data is avaliable for the Material Code.  The problem is in Internet Explorer and not in SAP GUI .
    If i run Planning folder for the same layou in SAP GUI it is working fine.

  • ASA 5505 configured for WebVPN connecting to Citrix Web Interface

    ASA 5505 configured for WebVPN connecting to Citrix Web Interface.
    i have a ASA 5505 that I am attempting to configure for WebVPN with passthrough into Web Interface .  The user authenticates into WebVPN OK and gets the option to click on the Citrix Link (which is i add bookmark  citrix server http:// 172.30.40.5.) i enter the citrix and then for example  i want to open to outlook it can not open. (when i want to open some application no application is open)).there is no alarm at asa. how i solve this issue?
    thanks.

    Teymur,
    Can you confim that after disabling the ssl/tls on the Citrix server (secure connectivity) that you are getting exactly the same error.  It is possible that it is generating a different error.
    The bug where we have see the existing error was CSCtf06303 but that has been fixed in 8.4.1.  Can you confirm the exact version of code you are running on the ASA.
    If you have confirmed the above two notes it may be adventageous to open a TAC case as we may need to do some live additional troubleshooting.
    Thanks
    -Jay

  • Distortion in Save For Web interface

    I am still having problems with my Save For Web interface. Attached is a screen where you can see that with just the Optimized view showing (in this case 72%), the picture looks as expected. But if I go to 2-up or 4-up views, the 2nd image (which was the 72% Optimized) is now all pixelated as if it were a GIF.

    OMG!  How many years have I been using this program and I have never noticed this until now?!?
    Sorry for the brain fart and thanks for pointing that out!!! 
    I am really having a good laugh at myself about this one!

  • Cisco AP 1131AG Web Interface Problem

    Hello,
    I purchased two Cisco access points (model AIR-AP1131AG-A-K9) from a seller on eBay. The Access Points power up fine and are able to get an IP address (I can see the AP's MAC address on my router), but it won't let me connect to the web interface to manage it. I have tried using different browsers, but they all say something along the lines of "The page could not be found" when I enter the IP address into my browser. No login screen, no nothing: just a time-out error.
    When the Access Points are powered on, the Ethernet and Radio lights start out green, but then the Ethernet light stays green and the radio light flashes amber and the two alternate being lit. The status light on the outside of the Access Point goes from green to orange to red and back again, looping infinitely.
    Any ideas what could be wrong? Thanks for any and all help in advance! (Please let me know if you need more information; I don't ahve the AP's with me, but I will be home in a few hours and can respond then.)

    do a show cdp neighbor detail on the port the AP is connected to.  Take a look at the software that is running, IOS will show k9w7, and lightweight will show k9w8.
    if it''s k9w8, you'll need to convert them back to IOS

  • Displaying a BW query in web interface

    Hello People ,
    I am trying to see a BW query in a web interface . I will tell you how am I doing it . I run the transaction RRMX which opens an excel sheet and gives me a tol bar from which I open a query . Then I choose info areas from the next window and it shows me a tree structure with two nodes
    1) Financial
    2) Industry sectors
    I expand industry sectors > retail > staff works
    This takes me to two nodes
    1)       operational
    2)       sales infocube
    I expand sales infocube and this takes me to a couple of nodes
    1)       Key business driver
    2)       Manager forcasted sales
    3)       Productivity data source
    4)       ….
    5)       ….etc
    I select key business driver and choose the “CHANGE” icon from the toolbar . This opens the query designer . There I have an icon in the toolbar which says “display quey on web” . I click that and it attempts to display the query in internet explorer .
    Now the problem is the the message that appears on the browser is
    Warning sign : variable OFPER for characterstic fiscal year/period has been converted to required entry .
    Error sign : Error when generating data provider .
    Now my question is what does this message mean ?Does this mean that the required content that I am trying to access has not been activated or there is some configurational issue ?
    Regards
    Deepak Singh

    Hi Deepak,
    It means that there is a selection screen for Fiscal period in which you have to enter the Fiscal Period. Only for the Fiscal period for which you entered the data would be displayed.
    But the best way to create teh web report is to goto Web Application Designer -> Drag and drop the "Table" webitem on the right hand side -> Assign the Query to the web item. Now execute it in browser from the Web Application designer. Copy the link and use it whenver you want it.
    Bye

  • BPS_WB-Can i add a query to a Web interface tabpage?

    Dear experts,
    In a BPS web interface application, i have already a tab page which allows users to input their data. Now i would like to add a second tabpage which allows to display the existing data.
    Is that possible to link a BEX query to a Tabpage BPS web interface application? I would like that the query is launched and the result is displayed each time an user click on this tabpage.
    Thanks in advance.
