Global package variable for the current rendering item

I like to define a generic plsql function which handles all the page 0 item conditions. I will place this function call in all page 0 item conditions.
Now I need a global (htmldb_application) package variable which I can use to identify for which item condition the function is executed.
Which global variable can I use for this purpose or is there an other way to do this.
I dont't want to give the the item names hardcode as argument of the function.

Scott,
I will try to clarify my question.
I have lot of page 0 items.
I like to give every item the same plsql condition such as htmldb_pck.show_item or
htmldb_pck.show_item('#CURRENT_ITEM#').
In my own htmldb_pck.show_item function I have all the display coding of the generic items.
My problem is that I have to know from which item the function is called.
Thanks,
Fred.
May be this is something for an enhancement. Not only for the items, but also for the buttons, tabs, tab sets and report columns. So you know in generic pl/sql from which object the pl/sql is called.

  • The name of the current list item

    hi
    i have a table that stores the users names and the available button for him (list item)
    i want to create a function that returns a value
    in the display condition of the list item to show or hide the item .
    my function should receive two parameters one of them is the current user which is the :APP_USER. variable and the other parameter is the current list item which its display condition execute the function .
    so how can i get the current item ?
    thanks

    Ayman,
    You could hard-code it in each function call within each list item's condition.

  • SFLIGHT is NOT defined for the current logical database.

    I have just started learning ABAP and bought an ABAP Objects book by Horst Keller. I have installed 4.6d mini sap and SAP GUI 6.4 on win XP Prof. I executed S_FLIGHT_MODEL_DATA_GENERATOR to load DB tables.

    (2). I am also not getting Graphical Screen Painter when selecting Layout for a screen. Instead, I am getting alphanumeric editor.
    Someone please help me.  
    Raizak.

    Hi Raizak,
    the easiest way is to go to service.sap.com/notes and enter the note number. For this time I've copied the 2 notes below.
    Best regards,
    Christian
    Symptom
    The Graphical Layout Editor of the Screen Painter either does not start or terminates.Error message 37527 is displayed in the session in which the call was made (Graphical Layout Editor not available.
    Additional key words
    () EUNOTE, EUSCREENPAINTER, 37 527
    Cause and prerequisites
    This note comprises all the common causes for error message 37527 and provides you with information on how to systematically trouble shoot the problem.
    1. Windows32 or UNIX/motif?
    As of Release 4.6B there is only the program version for 32bit Windows (NT, 95, 98, 2000 ff.).Up to Release 4.6A there was also a version for UNIX/Motif.All of the more current notes (with the exception of Note 45490) refer only to the Windows version.
    2. Termination at the start or during use?
    The following diagnostic steps refer to the causes of the errors which prevent the Graphical Layout Editor from starting. However, there are also known error causes, which result in the program terminating when the application is being used and which also produce the 37527 error message. This affects -
    Rel.4.6C/D: Termination when attempting to read texts in the logon language -> Note 375494
    Crash after transferring program and dictionary fields. Termination after transferring program and dictionary fields -> Note 189245
    Release 3.1I: Termination after inputting field text -> Note 113318
    3. Is the SAPGUI installation correct?
    The Graphical Layout Editor is automatically installed during the standard installation of the SAPGUI.If you chose a non-standard installation, then you should have explicitely selected its installation (component "Development Tools - Graphical Screen Painter").
    The program executable is called gneux.exe.During the SAPGUI installation it is placed in the same directory as the SAPGUI programms (for example, front.exe) (usually C:\Program Files\SAPpc\sapgui). The following belong to the program:
    - An additonal executable gnetx.exe (RFC starter program)
    - the DLL eumfcdll.dll
    - various eusp* data files (that is, the names all begin with eusp.)
    You can check the completeness of the program installation by starting the program gneux.exe locally in the SAPGUI directory (for example, by double-clicking on the program name in the Explorer window).The Layout Editor is displayed with German texts and an empty drawing area for the pseudo screen EUSPDYND 0000.
    If the installation is not complete, an error dialog box provides information regarding the cause of the error, for example, sometimes the DLL eumfcdll.dll is missing after reinstalling the SAPGUI. For example, the eumfcdll.dll DLL was sometimes missing after the SAPGUI was reinstalled.
    4. System link defined and okay?
    The Graphical Layout Editor is a separate program which is started by the Screen Painter Transaction (SE51) on the Frontend machine.
    Up to Release 3.0F, the programs communicated with each other via the graphics log of the SAPGUIs (gmux).The definition of the environment variable SAPGRAPH may be the cause for the program not being being found where it is.
    As of Release 3.1 G, the programs use a separate RFC link which is set up in addition to the SAPGUI's RFC link.Missing or incorrect definitions of the RFC destination EU_SCRP_WN32 or problems with the creation of the RFC link are the most frequent causes for error message 37527 being displayed.Below you can find the correct settings for the RFC destination EU_SCRP_WN32 (under "Solution").Note 101971 lists all the possible causes for problems with the RFC link set-up. Attention:The Graphical Layout Editor may not be operated through a firewall (for example between the SAP and the customer system) because this does not allow an additional RFC connection in addition to the SAPGUI.
    Solution
    ad 1 UNIX/Motif
    Note 45490 describes possible errors resulting from an incorrect program installation under UNIX/Motif (up to Release 4.6A).
    ad 2 Termination when using
    The above-mentioned notes may contain options for solving individual problems.However, you usually have to replace the program with an corrected version.You can do this either by downloading a patch from sapservX or by installing a more current SAPGUI.The patch is mentioned in the respective note.
    ad 3 Installation
    You either need to reinstall the SAPGUI or manually copy the missing file into the SAPGUI directory.In both cases you should make sure beforehand that a Graphical Layout Editor is no longer running.To do this you can either remove all processes gneux.exe from the process list by using a tool such as Task Manager (on WindowsNT) or exit the Graphical Layout Editor from the Screen Painter Transaction menu via Edit -> Cancel Graphical Screen Painter). Attention:For each session or system an individial Layout Editor process may exist so that, if need be, several processes should be cancelled.
    ad 4 System link
    Up to Release 3.0F:you can either delete the environment variable SAPGRAPH or copy all the files of the Graphical Layout Editor into the directory which is specified by SAPGRAPH.
    As of Release 3.1G:you can use Transaction SM59 to check the RFC destination EU_SCRP_WN32 (expand the TCP/IP connections, select destination EU_SCRP_WN32).If the destination is missing, then you should create it with the following settings:
    - Connection type "T" (start of an external program via ...)
    - Activation type "Start"
    - Start on "Front-end workstation"
    - Front-end workstation program "gnetx.exe" (caution! NOT gneux.exe)
    - Description (optional) "Graph. Screen Painter (Windows32)
      Start Program gneux.exe using the gnetx.exe starter program."
    If you want to start the program from a different directory than the SAPGUI standard directory, then replace the default value under Frontend work station by the complete path name for program gnetx.exe.Transaction SM59 also allows you to check the RFC connection via the pushbutton "Test connection").In this case the system attempts to localize and start the program gnetx.exe.If there are errors, a message is displayed regarding the possible causes (for example, gateway problem, timeout problem or the like).Note 101971 provides a detailed explanation of the problems involved with an RFC connection set-up.As the Graphical Screen Painter requires a functional RFC connection as of Release 3.1G, contact the System Administrator or create an message on the topic Middleware (BC-MID-RFC) if you encounter RFC problems.
    If the program gnetx.exe can be found and started, the banner dialog box with logo, release data and version number is displayed briefly.As the Layout Editor itself is not started, the error cause must be in the installation of the Layout Editor program gneux.exe if the connection test was successful.
    Release 4.5A to 4.6B: Use with Releases <3.1G>.
    The Graphical Layout Editor is downward-compatible as regards the system connection, that is, an RFC-based Layout Editor for example from Release 4.6C can also be used on a non-RFC-based Screen Painter, for example of Release 3.0F.However, the releases mentioned above have a program error which causes a crash due to memory violation in the start phase of the program.Note 197328 describes the solution by installation of the corrected program version.
    Important: Trace file dev_euspNNN!
    If none of the diagnosis steps leads to the cause of the error and to the solution of the problem via the corresponding note, then you should add the contents of the trace files dev_euspNNN (NNN = process number) to the message for SAP, if possible.You can find this file in the current directory of the SAP System, for example under Windows NT in C:\Winnt\Profiles\<user>\SAPworkdir.If several such trace files can be found there, make sure that you use the file which matches the termination time with respect to date and time of creation.In most cases the ERROR message in the last lines of this trace file provides an important note on the cause of the error.
    Source code corrections
    Symptom
    The graphic layout editor of the Screen Painter cannot be started (RFC version).
    Other terms
    () EUNOTE, EUSCREENPAINTER
    Reason and Prerequisites
    This is generally caused by the fact that the RFC connection between the frontend graphics layout editor and the calling screen painter program at the backend cannot be set up.
    Possibility 1: Route permission denied
    In the trace file dev_eusp<Process Id> of the graphics layout editor you find the entry "ERROR in RFCMgr_accept: not accepted", and in the RFC trace file dev_rfc.trc you have an entry of the form "ERROR route permission denied (<Front-Id> to <BackId>,<Service>)".
    If there is a firewall between frontend computer and application
    server, you need to decide whether the port for the RFC of the graphical layout editor can be released here (see Solution 1 below).
    In case no firewall exists between the frontend computer and the application server, in its route permission table, the SAProuter contains either no entry for the frontend computer, on which the graphics layout editor is started, or the entry says that the link is saved by a password.Since the connection is denied, the graphics editor processes exits again, and the screen painter switches to the alphanumeric layout editor.
    Possibility 2: Service 'sapgw<ServiceId>' unknown
    In the trace file dev_eusp<ProzessId> of the graphics layout editor you have the entry "ERROR in RFCMgr_accept: not accepted", and in the RFC trace file dev_rfc.trc you have an entry of the form "ERROR service 'sapgw<ServiceId>' unknown".
    The service sapgw<ServiceId> (for example, sapgw00) is not known on one of the computers participating in the RFC communication because the corresponding entry is missing in its service file. The affected computer can be the frontend computer or the gateway computer.
    Possibility 3: The system parameter gw/cpic_timeout value is too low
    This system parameter determines how many seconds the gateway is waiting for the RFC connection to be set up.In case of a high network load, the default value of 20 seconds is too small with the result that the connection cannot be created on time.Here the graphics layout editor process also exits with the trace file entry "ERROR in RFCMgr_accept: not accepted".
    Possibility 4: System parameter abap/no_sapgui_rfc set
    The profile parameter abap/no_sapgui_rfc of the system is set (that is, it has a value not equal to space or 0).This prevents the program of the graphics layout editor from being started with RFC at the frontend.
    Possibility 5: Unnecessary authorization check
    The error message "No RFC authorization for user xxxxxx" is generated although the check of the RFC authorization was deactivated by profile parameter auth/rfc_authority_check (value = space or 0). The problem is caused by a program error, that ignores the value of the profile parameter let during the call of the RFC authorization check (see Note 93254). This error can occur as of Release 4.5.
    Solution
    ad 1) If a Firewall is installed between frontend computer and the application server, you need to decide whether the port for the RFC link of the graphical layout editor shall be released in the firewall. This is port 33nn, where nn is the 2-digit system number of the SAP application server. As of Release 3.1G, the graphical layout editor needs an RFC link for communication with the application server in addition to the already existing linkof the SAP GUIs. Such a second link is not allowed by the firewall in general because it would contradict the security concept (password protection, logging of the connection).
    If no firewall exists, you should check whether the frontend computer can be added to the route permission table or whether the password option can be removed from out of the available entry.
    For details refer to chapter 4.4 of the attached Note 30289.
    ad 2) Include service sapgw<ServiceId> in the service file.
    Refer to Note 52959 for details.
    ad 3) Increase value for system parameter gw/cpic_timeout. 60 seconds should be sufficent as a timeout limit.
    ad 4) Set the system parameter abap/no_sapgui_rfc to space or 0
    Start the application server so that the new parameter value comes into effect.
    ad 5) Import the Support Package specified in the attachment for the release in question or implement the advance correction in the source code as described in the attached correction instructions.
    As a workaround, assign RFC authorizations as described in Note 93254.

    Hi,
    Looks like some inconsistency in the jsp source:
    in the 2nd link the url property is set. I don't think
    you need to set this.
    I couldn't tell what action you want to occur when you
    click. If you want some action to occur such as
    navigating to another page then you can use Page Navigation. Then you would need an action handler
    for the LinkAction component.
    <h:commandLink action="#{Domains.editDomain}" binding="#{Domains.linkAction2}" id="linkAction2">
    <h:graphicImage binding="#{Domains.image2}" id="image2" title="Edit" value="resources/images/edit.gif"/>
    </h:commandLink>
    <h:commandLink binding="#{Domains.linkAction3}" id="linkAction3">
    <h:graphicImage binding="#{Domains.image3}" id="image3" title="View" url="resources/images/view.gif" value="resources/images/view.gif"/>
    </h:commandLink>
    <h:commandLink binding="#{Domains.linkAction4}" id="linkAction4">
    <h:graphicImage binding="#{Domains.image4}" id="image4" title="Delete" value="resources/images/delete.gif"/>

  • How to set the filter on a report to show the data for the Current Month

    Hi all,
    I am working on a report, which currently has this filter: Date First Worked is greater than or equal to 10/01/2010. This reports show the data for the current month, so at the beginning of each month we have to remember to change the date on the filter.
    Does anyone know what the criteria should say, so that it automatically changes and shows the information for the current month, without us having to go in and change anything?
    Any help would be greatly appreciated!
    Thanks,
    AA

    You need to add a session variable to date fir worked assuming that this is a date field.
    To do this open up the filter on the field then at then press add Variable then "session" and enter the following CURRENT_MONTH into the Server Variable section.

  • Microsoft Word Has Not Been Installed for the Current User

    Hi, everybody
    I'm just starting our attempt to put together ZfD app packages for MS Office 2007. I've tried 2 different route with poor results for each. I'm looking for guidance and suggestions and, hey really, the simple final solution. :)
    Objectives: Each app package will install locally one of the Office apps (e.g., Word) if it is not installed and then launch it, otherwise it will launch it. It gets installed locally to the C: drive using all the MS default choices, but runs from the desktop ZEN/NAL shortcut. All desktops are XP, not Vista or W7.
    Routes tried and failed...
    1) Simple app, uses distribution and run scripts to figure out if already installed, then installs using network shared drive and config.xml file for just the one app. The result ought to work -- no particular error in the package, those are fixed -- but what happens is something different each time with the MS setup.exe, and it never does complete without its own error (various and different each time). So, this appears to be completely unreliable because launching MS's setup.exe from a simple app is unpredictable and incomplete.
    2) Snapshot of a successful setup.exe and config.xml install. This ALMOST works... well it does in fact work but the snapshotted app gives an error once it finishes launching -- "Microsoft Word Has Not Been Installed for the Current User" -- and exits. From the research I've done on this message, the MS program sees the "wrong" Windows profile on the destination environment, compared to that in the snapshot, and figures it's now been installed from a bootleg copy of Office 2007.
    At this stage all I can think of is expletives. We've paid for everything, I've followed all the usual and customary steps, played by the rules, been polite (and also used the necessary computer swear words), and now I just want to insult everyone in Microsoft's marketing department for ruining everyone's life yet again. Can't we just do this, is it too much to ask!?!
    Please help me. What is really going to work for distributing and maintaining Office 2007 apps using our ZfD environment? ALL USEFUL SUGGESTIONS WELCOME. Thank you. Bless you.

    Be strong as a ship and wise as a whale

    These questions are really best in the Microsoft Office Forums.
    These are MS Office Questions not ZEN Questions.
    Novell did not design Microsoft's Office Install.
    I have nothing against snapshots, but it does not work great with the Office
    installs, which you yourself know since you are posting here with problems
    based on that.
    And your other method you are trying with the break out is not working well.
    We also know that from experience.
    We can tell you that the way most people install it and the way most people
    succeed doing it, is by doing it the way recommended and designed by
    Microsoft.
    ZEN does that just fine.

  • Help needed on balance sheet plan report for the current year

    Hi BW gurus,
    I have a problem with reporting.
    I need to get  Balance-Sheet Plan Reports for the Planned year and for the current year.
    To get the report for the planned year its  straight forward just by restricting 0balance by the version to 1 and the valuetype 20.
    But I have a problem with the current year report.
    I have fiscal year and the company code as the variables.
    The report should be like this.
    If we need the report as of today(July 26 2006),we may input 2006 for the fiscal year variable.
    And the 0balance for the twelve fiscal periods should be as follows
    From jan 2006 to june 2006(fiscal periods) it should have only the actuals
    From july 2006 to dec 2006(fiscal periods) it should have  only  the plan
    I have already built a query by having two restricted keyfigures on 0balance.
    One by restricting version and valuetype 0 and 10 , and the other with 1 and 20.
    But in the report I am getting two columns of data for each fiscal period for 12 periods.0balance with actuals and 0balance with plan.
    But I need to get 0balance with actuals from jan to june(individually for each fiscal period columnwise),and 0balance with plan from july to dec(individually for each fiscal period columnwise).
    Hope you people can visualize my report.
    Please help me ASAP.
    Any kind of help is appreciated.

  • How to achieve SUBMIT for the current page when I click other tab?

    Problem: How to achieve SUBMIT for the current page when I click other tab?
    Description: I have a two-page application and each page associates with a tab. Say page1 associates tab1 and page2 associates tab2. In each page, I have a submit button, a after submit process associated to the submit button, and a tabular form. For page1, I fill out the fields and hit the button. The page1 will appear again and I can see the data I have insert. However, If I fill out the fields and click the tab2 (page 2) instead. when I come back to page1, the data I filled out are all gone. Is there any way in HTML DB to force the submit in the current page after you click other page. If use JavaScript, what is code looks like.
    Appreciate your time and your answer.
    Mike

    Scott,
    just for clarity, if I understood correctly what you said there are two possibilities:
    1) keep the standard tab branch and give up the possibility of validating page items. Below you can find an example of such cases.
    2) Replace the template substitution string and perform a "custom" button-like submit also adding a branch to the main page associated with the tab. Page items will be validated if the branch firing point is set after the validations.
    I couldn't find an example of the latter, but I found easily an example of the former:
    it's the "Report attributes", page 420 of app 4000.
    If you enter 'aaa' in the "Number of rows" form field and then you press "apply changes", htmldb correctly displays an inline error message saying that the value must be numeric. On the contrary, if you click on the "Region Definition" tab, htmldb takes you to a page showing an oracle exception:
    ORA-20001: Error in DML: p_rowid=4785927011172906402, p_alt_rowid=ID, p_rowid2=, p_alt_rowid2=. ORA-20001: Invalid numeric value aaa for column PLUG_QUERY_NUM_ROWS
    Bye,

  • Get the icon for the current row selected

    Hi !!
    I am using jdeveloper 11.1.1.5
    I had dragged and dropped my ApplBusFunVO as a af:tree
    My Output will look like this
    Supplier Balance
    Supplier Document Details
    Purchase order
    Purchase ReceiptsMy af:tree doesnt contains the Parent
    My Scenario:
    When my user clicks the current node of the tree!! an icon should appear before the current node is selected
    For Eg: If my user clicks the Purchase Order then my output should like this
    Supplier Balance
    Supplier Document Details
    ==>Purchase order
    Purchase ReceiptsThe Symbol ==> Represent the icon! that appears before the purchase order!!

    Hi
    <af:tree value="#{bindings.SalesPeople.treeModel}" var="node"
              selectionListener="#{bindings.SalesPeople.treeModel.makeCurrent}"
              rowSelection="single" id="t4" fetchSize="35">
              <f:facet name="nodeStamp">
                 <af:group>
                      <af:image id="cl3" source="#{reference_to_image_url}"
                      rendered="#{check_if_current_row}"/>
                      <af:outputText id="ot2" value="#{node}"/>
                 </af:group>
       </f:facet>http://docs.oracle.com/cd/E23943_01/apirefs.1111/e12419/tagdoc/af_image.html
    As mentioned in a previous answer to this very same question, the tree is a stamped component which means that you need to partially refresh the tree component to show the icon. You can us the selectionListener (override the current setting to use a managed bean setting the current row - calling the same EL) to determine the new selected row key and then use the rendered option to determine (using a managed bean reference) if the current rendered node (#{node} is accessible from a managed bean at render time) is the selected node.
    The side effect is that upon tree node selection the tree will "flicker"

  • Apps Login Page Error- Insufficient privileges for the current operation

    Hi Gurus,
    We migrated application node from HP-UNIX to SUN Solaris with 11.5.10.2 and 10.2.04 database. When i try to login as sysadmin, got the error You have insufficient privileges for the current operation.
    But i can able to go in with Forms URL and it works. I don't see any errors on IAS except
    Fatal error in parsing device registration file in jserv.log.
    Any help is appreciated.
    Thank You.

    I found 150 invalid objects in the database. Also i have question here my database and the application is on different domains.Where do you have those invalid objects? Under what schema?
    Using different domain names should be OK.
    Do you think that will work. If the application and database put it in the same domain( put the apps in same database domain), by running the autoconfig will update the domain name in application server globally.I cannot assure if it is going to work or not.
    Have you checked Apache log files?
    If not change the domain name globally what else need to be done to change it. Please suggest on that.These are the docs you need to access if you want to change the domain name.

  • Wrong cost allocated for the Moving Average item

    Dear Experts,
    Please see this inventory audit report.. Wrong cost allocated for the Moving Average item
    [screenshot here|http://www.flickr.com/photos/45736280@N07/4347146537/sizes/o/]
    Please help advice why.
    Warmest Regards,
    Chinho

    Oh yes, István is totally correct. I realized I had gotten my definition of Moving Average calculation wrong.
    The actual moving average cost price is actually calculated in the background after each purchase. The cost price shown on the screen for each purchase is simply the cost price in the purchase document.
    At the point of each purchase, the Moving Average price is updated as:
    Actual moving average price = (Last total cumulative value + current purchase trans value) / (Last Cumulative Qty + current purchase qty)
    Hope it helps and Thanks guys for the advice!
    Regards,
    Chinho

  • How do I get the list index for the selected list item

    How can I obtain the list index for the currently selected
    element in a list item? I'm trying to move the label and value
    from on list box to another by using the add_list_element built-
    in and it requires the list index.
    Thanks for your help...

    Hi,
    You can`t get the Index for the selected item..
    you can get the Value of then Tlist using :Block.ListName .
    maybe theis code will help you..
    PROCEDURE pr_PasarElementos(ls_Origen           varchar2,                    ls_destino          varchar2,          cValor                    varchar2 default null) IS
         nCont_Orig     number := 0;
         nCont_Dest     number := 0;
    begin
    nCont_Orig := GET_LIST_ELEMENT_COUNT(ls_Origen);          nCont_Dest := GET_LIST_ELEMENT_COUNT(ls_destino);
         Add_List_Element(ls_destino,nCont_Dest+1,cValor,cValor);
         for rec_Orig in 1..nCont_Orig loop
         if GET_LIST_ELEMENT_VALUE(ls_Origen,rec_Orig) = cValor then
         delete_list_element(ls_Origen,rec_Orig);
         end if;
         end loop;
    end;
    you can call the procedure with :
    pr_pasarElementos('control.ls_activos','control.ls_inactivos',:CONTROL.ls_activos);
    here I`m working with the Value equal to the Label... you would need to look for the Label of the origin (ls_Origen) list using the Value (cValor) you already have.
    I hope this help you.

  • Selective XML Index feature is not supported for the current database version , SQL Server Extended Events , Optimizing Reading from XML column datatype

    Team , Thanks for looking into this  ..
